Class Configuration

java.lang.Object
net.sf.saxon.Configuration
All Implemented Interfaces:
SourceResolver, NotationSet
Direct Known Subclasses:
ProfessionalConfiguration
public class Configuration extends Object implements SourceResolver, NotationSet
This class holds details of user-selected configuration options for a set of transformations and/or queries. When running XSLT, the preferred way of setting configuration options is via the JAXP TransformerFactory interface, but the Configuration object provides a finer level of control. As yet there is no standard API for XQuery, so the only way of setting Configuration information is to use the methods on this class directly.

As well as holding configuration settings, this class acts as a factory for classes providing service in particular areas: error handling, URI resolution, and the like. Some of these services are chosen on the basis of the current platform (Java or .NET), some vary depending whether the environment is schema-aware or not.

The Configuration provides access to a NamePool which is used to manage all the names used in stylesheets, queries, schemas, and source and documents: the NamePool allocates integer codes to these names allowing efficient storage and comparison. Normally there will be a one-to-one relationship between a NamePool and a Configuration. It is possible, however, for several Configuration objects to share the same NamePool. Until Saxon 8.9, by default all Configuration objects shared a single NamePool unless configured otherwise; this changed in 8.9 so that the default is to allocate a new NamePool for each Configuration.

The Configuration establishes the scope within which node identity is managed. Every document belongs to a Configuration, and every node has a distinct identity within that Configuration. In consequence, it is not possible for any query or transformation to manipulate multiple documents unless they all belong to the same Configuration.

Saxon-EE has a subclass of the Configuration class which provides the additional services needed for schema-aware processing. The EnterpriseConfiguration also holds a cache of loaded schema components used for compiling schema-aware transformations and queries, and for validating instance documents.

Since Saxon 8.4, the JavaDoc documentation for Saxon attempts to identify interfaces that are considered stable, and will only be changed in a backwards-incompatible way if there is an overriding reason to do so. These interfaces and methods are labelled with the JavaDoc "since" tag. The value 8.n indicates a method in this category that was introduced in Saxon version 8.n: or in the case of 8.4, that was present in Saxon 8.4 and possibly in earlier releases. (In some cases, these methods have been unchanged for a long time.) Methods without a "since" tag, although public, are provided for internal use or for use by advanced users, and are subject to change from one release to the next. The presence of a "since" tag on a class or interface indicates that there are one or more methods in the class that are considered stable; it does not mean that all methods are stable.

Since:
8.4

      This method fails if the specified configuration class cannot be loaded, but it does not check whether there is a license available.

      Parameters:
      classLoader - - the class loader to be used. If null, the context class loader for the current thread is used.
      className - - the name of the configuration class. Defaults to "com.saxonica.config.ProfessionalConfiguration" if null is supplied. This allows an assembly qualified name to be supplied under .NET. The class, once instantiated, must be an instance of Configuration.
      Returns:
      the new ProfessionalConfiguration or EnterpriseConfiguration
      Throws:
      RuntimeException - if the required Saxon edition cannot be loaded
      Since:

      public void importLicenseDetails(Configuration config)

    • getEditionCode

      public String getEditionCode()
      Get the edition code identifying this configuration: "HE", "PE" or "EE"
      Returns:
      the code identifying the Saxon edition associated with this configuration

    • setProcessor

      public void setProcessor(Configuration.ApiProvider processor)
      Save the ApiProvider object that owns this Configuration in the relevant API.

      Note: it is possible to use multiple APIs over the same Configuration. This mechanism is only capable of holding one of these, and is therefore only really useful in cases where the API in use is homogeneous.

      Parameters:
      processor - This can be any ApiProvider, but it is typically one of the following:
      • When using the Java s9api interface, the net.sf.saxon.s9api.Processor
      • When using the .NET interface, the Saxon.Api.Processor
      • When using the JAXP transformation interface, the JAXP TransformerFactory
      • When using the JAXP XPath interface, the JAXP XPathFactory
      • When using the JAXP Schema interface, the JAXP SchemaFactory
      • When using XQJ, the XQDataSource
      Since:
      9.2. Changed in 9.9 to require an Configuration.ApiProvider rather than any Object.

    • getProcessor

      public Configuration.ApiProvider getProcessor()
      Get the Processor object that created this Configuration in the relevant API.

      The main purpose of this interface is to allow extension functions called from a stylesheet or query to get access to the originating processor. This is particularly useful when methods are static as there is then limited scope for passing data from the calling application to the code of the extension function.

      Returns:
      the processor that was supplied to the setProcessor(ApiProvider) method, or null if this method has not been called. In practice this property is used to hold one of the following:
      • When using the Java s9api interface, the net.sf.saxon.s9api.Processor
      • When using the .NET interface, the Saxon.Api.Processor
      • When using the JAXP transformation interface, the JAXP TransformerFactory
      • When using the JAXP XPath interface, the JAXP XPathFactory
      • When using the JAXP Schema interface, the JAXP SchemaFactory
      • When using XQJ, the XQDataSource
      Since:
      9.2. Changed in 9.9 to return an Configuration.ApiProvider rather than any Object.

    • getProductTitle

      public String getProductTitle()
      Get a message used to identify this product when a transformation is run using the -t option
      Returns:
      A string containing both the product name and the product version
      Since:

      name - the name of the feature for use in diagnostics
      localLicenseId - identifies an embedded license, or -1 if not applicable
      Throws:
      LicenseException - if the feature is not licensed. This is a RunTimeException, so it will normally be fatal.

    • disableLicensing

      public void disableLicensing()
      Instruct Saxon to run as if no license is available. This method is provided for testing purposes, so that tests with and without a license can be run without making changes to the classpath.

    • isFeatureAllowedBySecondaryLicense

      public boolean isFeatureAllowedBySecondaryLicense(int localLicenseId, int feature)
      Ask whether a particular feature is enabled by an embedded license (embedded in a SEF file)
      Parameters:

    • requireProfessionalLicense

      public void requireProfessionalLicense(String featureName) throws LicenseException
      Assert that a PE license is required, and fail if none is available
      Parameters:
      featureName - name of the required feature, to include in the error message. This can be any name (for example "XQuery Update"), it does not have to correspond with a particular property held in the license file.
      Throws:
      LicenseException - if no license key is available

    • getLicenseFeature

      public String getLicenseFeature(String name)
      Get the value of a named license feature
      Parameters:
      name - the name of the feature. This is one of the properties explicitly recorded in the license file, for example "Licensor", "Licensee", "Email", "Issued", "Serial".
      Returns:
      the value of the feature if present, or null otherwise

    • getLicenseFeatures

      public Properties getLicenseFeatures()
      Get all license features, as a Properties object mapping feature names to feature values.
      Returns:
      a map containing all license features as name-value pairs. The names and values are those explicitly recorded in the license file, for example "Issued":"2022-11-25". If there is no license, the method returns null.

      Returns:
      the DynamicLoader in use - either a user-supplied DynamicLoader, or the standard one supplied by the system.

    • getClass

      public Class<?> getClass(String className, boolean tracing) throws XPathException
      Load a class using the class name provided. Note that the method does not check that the object is of the right class.

      This method is intended for internal use only. The call is delegated to the DynamicLoader, which may be overridden by a user-defined DynamicLoader.

      Parameters:
      className - A string containing the name of the class, for example "com.microstar.sax.LarkDriver"
      tracing - true if diagnostic tracing is required
      Returns:
      an instance of the class named, or null if it is not loadable.
      Throws:
      XPathException - if the class cannot be loaded.

    • getInstance

      public Object getInstance(String className) throws XPathException
      Instantiate a class using the class name provided. Note that the method does not check that the object is of the right class.

      This method is intended for internal use only. The call is delegated to the DynamicLoader, which may be overridden by a user-defined DynamicLoader.

      Diagnostic output is produced if the option "isTiming" is set (corresponding to the -t option on the command line).

      Parameters:
      className - A string containing the name of the class, for example "com.microstar.sax.LarkDriver"
      Returns:
      an instance of the class named, or null if it is not loadable.
      Throws:
      XPathException - if the class cannot be loaded.

    • getResourceResolver

      public ResourceResolver getResourceResolver()
      Returns the current resource resolver. If the configuration does not have a resolver when this method is called, a default CatalogResourceResolver will be constructed and returned.
      Returns:
      The resolver.

    • setResourceResolver

      public void setResourceResolver(ResourceResolver resolver)
      Set the ResourceResolver to be used in this configuration. This is used as a fallback whenever the local ResourceResolver for a particular task (for example the XsltCompiler or the XQueryEvaluator) either (a) has not been set, or (b) has been called and returns null.

      If a user-written ResourceResolver is supplied then it must be able to handle a wide range of requests, not just for XML source documents and stylesheets, but also for schemas, unparsed text resources, and external entities. One way to achieve this by inheriting from the CatalogResourceResolver, only overriding those methods that need to change. Another method is to construct a ChainedResourceResolver that first handles specific cases, and then passes control to the standard ResourceResolver.

      In cases where the request is for a non-XML resource, the object delivered by the ResourceResolver must be a StreamSource.

      The ResourceResolver may return null to indicate that the URI is to be resolved by the fallback DirectResourceResolver.

      Parameters:
      resolver - The ResourceResolver to be used.
      Since:
      11.1. Replaces setURIResolver()

    • setParameterizedURIResolver

      @Deprecated public void setParameterizedURIResolver()
      Deprecated.
      since 11.1 - use setBooleanProperty(Feature.RECOGNIZE_URI_QUERY_PARAMETERS, true);
      Set the URIResolver to a URI resolver that allows query parameters after the URI

    • getProtocolRestrictor

      public ProtocolRestrictor getProtocolRestrictor()
      Get the ProtocolRestrictor in use. This restricts the URI schemes that may be used when dereferencing a resource. The ProtocolRestrictor can be set by setting the property Feature.ALLOWED_PROTOCOLS to a comma-separated list of permitted protocols.
      Returns:
      the ProtocolRestrictor in use

    • makeResourceResolver

      public ResourceResolver makeResourceResolver(String className) throws XPathException
      Create an instance of a URIResolver with a specified class name. Note that this method does not register the URIResolver with this Configuration.
      Parameters:
      className - The fully-qualified name of the URIResolver class
      Returns:
      The newly created URIResolver
      Throws:
      XPathException - if the requested class does not implement the ResourceResolver interface

      Parameters:
      err - the exception to be reported

    • setStandardErrorOutput

      public void setStandardErrorOutput(PrintStream out)
      Set the standard error output to be used in all cases where no more specific destination is defined. This defaults to System.err.

      The method has no effect unless the getLogger() object is an instance of StandardLogger. In that case it calls StandardLogger.setPrintStream(PrintStream)

      Parameters:
      out - the stream to be used for error output where no more specific destination has been supplied. The caller is responsible for closing this stream after use (if necessary).
      Since:
      9.3

    • setLogger

      public void setLogger(Logger logger)
      Register a new logger to be used in the Saxon event logging mechanism
      Parameters:
      logger - the Logger to be used as default. The caller is responsible for ensuring that this is closed after use (if necessary), which can be achieved by calling either Logger.close() or close();
      Since:
      9.6

    • setXMLVersion

      public void setXMLVersion(int version)
      Set the XML version to be used by default for validating characters and names. Note that source documents specifying xml version="1.0" or "1.1" are accepted regardless of this setting. The effect of this switch is to change the validation rules for types such as Name and NCName, to change the meaning of \i and \c in regular expressions, and to determine whether the serializer allows XML 1.1 documents to be constructed.
      Parameters:
      version - one of the constants XML10 or XML11
      Since:
      8.6

    • getParseOptions

      public ParseOptions getParseOptions()
      Get the parsing and document building options defined in this configuration
      Returns:
      the parsing and document building options. Note that any changes to this ParseOptions object will be reflected back in the Configuration; if changes are to be made locally, the caller should create a copy.
      Since:
      9.2. From 12.x the ParseOptions object is immutable, which means any changes must be written back using setParseOptions(net.sf.saxon.lib.ParseOptions)

    • setParseOptions

      public void setParseOptions(ParseOptions options)
      Set the parsing and document building options to be used in this configuration.

    • setMediaQueryEvaluator

      public void setMediaQueryEvaluator(Comparator<String> comparator)
      Set a comparator which can be used to assess whether the media pseudo-attribute in an xml-stylesheet processing instruction matches the media requested in the API for the transformation
      Parameters:
      comparator - a comparator which returns 0 (equals) when the first argument of the compare method is the value of the media attribute in the xml-stylesheet processing instruction, and the second argument is the value of the required media given in the calling API. The default implementation always returns 0, indicating that the media pseudo-attribute is ignored. An alternative implementation, consistent with previous Saxon releases, would be compare the strings for equality. A fully conformant implementation could implement the syntax and semantics of media queries as defined in CSS 3.

    • getMediaQueryEvaluator

      public Comparator<String> getMediaQueryEvaluator()
      Get a comparator which can be used to assess whether the media pseudo-attribute in an xml-stylesheet processing instruction matches the media requested in the API for the transformation

The default implementation always returns 0, indicating that the media pseudo-attribute is ignored. An alternative implementation, consistent with previous Saxon releases, would be to compare the strings for equality. A fully conformant implementation could implement the syntax and semantics of media queries as defined in CSS 3.

      public void setCollationURIResolver(CollationURIResolver resolver)
      Set a CollationURIResolver to be used to resolve collation URIs (that is, to take a URI identifying a collation, and return the corresponding collation). Note that Saxon attempts first to resolve a collation URI using the resolver registered with the Controller; if that returns null, it tries again using the resolver registered with the Configuration.

      Note that it is undefined whether collation URIs are resolved at compile time or at run-time. It is therefore inadvisable to change the CollationURIResolver after compiling a query or stylesheet and before running it.

      Parameters:
      resolver - the collation URI resolver to be used. This replaces any collation URI resolver previously registered.
      Since:
      8.5

      Parameters:
      collationName - the collation name as an absolute URI
      Returns:
      the StringCollator with this name if known, or null if not known
      Throws:
      XPathException - if the collation URI is recognized but is invalid; for example, if it is a URI that takes parameters, and the parameters are invalid. If a user-supplied collation URI resolver is in use, then any exception thrown by that resolver is passed on to the caller.

      Parameters:
      collationURI - the collation name as a relative or absolute URI
      baseURI - the base URI to be used to resolve the collationURI if it is relative
      Returns:
      the StringCollator with this name if known, or null if not known

      Parameters:
      collationURI - the collation name as a relative or absolute URI
      baseURI - the base URI to be used to resolve the collationURI if it is relative; may be null if the supplied collationURI is known to be absolute
      errorCode - the error to raise if the collation is not known
      Returns:
      the StringCollator with this name if known, or null if not known

      public String getSourceParserClass()
      Get the name of the class that will be instantiated to create an XML parser for parsing source documents (for example, documents loaded using the document() or doc() functions).

      This method is retained in Saxon for backwards compatibility, but the preferred way of choosing an XML parser is to use JAXP interfaces, for example by supplying a JAXP SAXSource object initialized with an appropriate implementation of org.xml.sax.XMLReader.

      Returns:
      the fully qualified name of the XML parser class

    • setDefaultSerializationProperties

      public void setDefaultSerializationProperties(Properties props)
      Set the default serialization properties.

      The method name is a misnomer, retained for backwards compatibility. A SerializationProperties object contains a set of Properties holding simple properties, together with an optional CharacterMap holding a character map. This method returns the simple properties only. In fact the default properties held in the Configuration only contain simple properties, and never a character map.

      Parameters:
      props - the default properties

    • getDefaultSerializationProperties

      public Properties getDefaultSerializationProperties()
      Get the default output properties. The returned value can be modified in-situ using methods such as Properties.setProperty(String, String) to change the defaults in force for the Configuration.

    • processResultDocument

      public void processResultDocument(ResultDocument instruction, PushEvaluator content, XPathContext context) throws XPathException
      Process an xsl:result-document instruction. The Saxon-HE version of this method simply executes the instruction. The Saxon-EE version starts a new thread, and executes the instruction in that thread.
      Parameters:
      instruction - the instruction to be executed
      content - the expression that defines the content of the new result document
      context - the evaluation context
      Throws:
      XPathException - if any dynamic error occurs

    • getMultithreadedItemMappingIterator

      public SequenceIterator getMultithreadedItemMappingIterator(SequenceIterator base, ItemMappingFunction action) throws XPathException
      Get an item mapping iterator suitable for multi-threaded execution, if this is permitted
      Parameters:
      base - iterator over the input sequence
      action - mapping function to be applied to each item in the input sequence.
      Returns:
      an iterator over the result sequence
      Throws:
      XPathException - if (for example) a dynamic error occurs while priming the queue

    • isTiming

      public boolean isTiming()
      Determine whether brief progress messages and timing information will be output.

      This method is provided largely for internal use. Progress messages are normally controlled directly from the command line interfaces, and are not normally used when driving Saxon from the Java API.

      Returns:
      true if these messages are to be output.

    • setTiming

      public void setTiming(boolean timing)
      Determine whether brief progress messages and timing information will be output.

      This method is provided largely for internal use. Progress messages are normally controlled directly from the command line interfaces, and are not normally used when running from a Java application.

      The name of the method is poorly chosen, since many of the progress messages that are output have little to do with timing or instrumentation.

      If enabled, the relevant messages will be sent either to the destination set using setLogger(Logger) or to the destination set using setStandardErrorOutput(PrintStream), depending on the message.

      Parameters:
      timing - true if these messages are to be output.

    • isVersionWarning

      @Deprecated public boolean isVersionWarning()
      Deprecated.
      since 10.0; the method has had no effect since Saxon 9.8
      Determine whether a warning is to be output when running against a stylesheet labelled as version="1.0". The XSLT specification requires such a warning unless the user disables it.
      Returns:
      always false.
      Since:
      8.4

    • setVersionWarning

      @Deprecated public void setVersionWarning(boolean warn)
      Deprecated.
      since 10.0; the method has had no effect since Saxon 9.8
      Determine whether a warning is to be output when the version attribute of the stylesheet does not match the XSLT processor version. (In the case where the stylesheet version is "1.0", the XSLT specification requires such a warning unless the user disables it.)
      Parameters:
      warn - ignored.
      Since:
      8.4

    • isValidation

      public boolean isValidation()
      Determine whether the XML parser for source documents will be asked to perform validation of source documents
      Returns:
      true if DTD validation is requested.
      Since:
      8.4

    • setValidation

      public void setValidation(boolean validation)
      Determine whether the XML parser for source documents will be asked to perform DTD validation of source documents
      Parameters:
      validation - true if DTD validation is to be requested.
      Since:
      8.4

    • makeDocumentProjector

      public FilterFactory makeDocumentProjector(PathMap.PathMapRoot map)
      Create a document projector for a given path map root. Document projection is available only in Saxon-EE, so the Saxon-HE version of this method throws an exception
      Parameters:
      map - a path map root in a path map. This might represent the call to the initial context item for a query, or it might represent a call on the doc() function. The path map contains information about the paths that the query uses within this document.
      Returns:
      a push filter that implements document projection
      Throws:
      UnsupportedOperationException - if this is not a schema-aware configuration, or if no Saxon-EE license is available

    • makeDocumentProjector

      public FilterFactory makeDocumentProjector(XQueryExpression exp)
      Create a document projector for the document supplied as the initial context item in a query. Document projection is available only in Saxon-EE, so the Saxon-HE version of this method throws an exception
      Parameters:
      exp - an XQuery expression. The document projector that is returned will be for the document supplied as the context item to this query.
      Returns:
      a push filter that implements document projection
      Throws:
      UnsupportedOperationException - if this is not a schema-aware configuration, or if no Saxon-EE license is available

    • getSchemaValidationMode

      public int getSchemaValidationMode()
      Ask whether source documents (supplied as a StreamSource or SAXSource) should be subjected to schema validation, and if so, in what validation mode
      Returns:
      the schema validation mode previously set using setSchemaValidationMode(), or the default mode Validation.STRIP otherwise.

    • setSchemaValidationMode

      public void setSchemaValidationMode(int validationMode)
      Say whether source documents (supplied as a StreamSource or SAXSource) should be subjected to schema validation, and if so, in what validation mode. This value may be overridden at the level of a Controller for an individual transformation or query.
      Parameters:
      validationMode - the validation (or construction) mode to be used for source documents. One of Validation.STRIP, Validation.PRESERVE, Validation.STRICT, Validation.LAX
      Since:
      8.4

    • setValidationWarnings

      public void setValidationWarnings(boolean warn)
      Indicate whether schema validation failures on result documents are to be treated as fatal errors or as warnings. Note that all validation errors are reported to the error() method of the ErrorListener, and processing always continues except when that method chooses to throw an exception. At the end of the document, a fatal error is thrown if (a) there have been any validation errors, and (b) this option is not set.
      Parameters:
      warn - true if schema validation failures are to be treated as warnings; false if they are to be treated as fatal errors.
      Since:
      8.4

    • isValidationWarnings

      public boolean isValidationWarnings()
      Determine whether schema validation failures on result documents are to be treated as fatal errors or as warnings. Note that all validation errors are reported to the error() method of the ErrorListener, and processing always continues except when that method chooses to throw an exception. At the end of the document, a fatal error is thrown if (a) there have been any validation errors, and (b) this option is not set.
      Returns:
      true if validation errors are to be treated as warnings (that is, the validation failure is reported but processing continues as normal); false if validation errors are fatal.
      Since:
      8.4

    • setExpandAttributeDefaults

      public void setExpandAttributeDefaults(boolean expand)
      Indicate whether attributes that have a fixed or default value are to be expanded when generating a final result tree. By default (and for conformance with the W3C specifications) it is required that fixed and default values should be expanded. However, there are use cases for example when generating XHTML when this serves no useful purpose and merely bloats the output.

      This option can be overridden at the level of a PipelineConfiguration

      Parameters:
      expand - true if fixed and default values are to be expanded as required by the W3C specifications; false if this action is to be disabled. Note that this only affects the validation of final result trees; it is not possible to suppress expansion of fixed or default values on input documents, as this would make the type annotations on input nodes unsound.
      Since:
      9.0

    • isExpandAttributeDefaults

      public boolean isExpandAttributeDefaults()
      Determine whether elements and attributes that have a fixed or default value are to be expanded. This option applies both to DTD-defined attribute defaults and to schema-defined defaults for elements and attributes. If an XML parser is used that does not report whether defaults have been used, this option is ignored.

      This option can be overridden at the level of a PipelineConfiguration

      Returns:
      true if elements and attributes that have a fixed or default value are to be expanded, false if defaults are not to be expanded. The default value is true. Note that the setting "false" is potentially non-conformant with the W3C specifications.
      Since:
      9.0

    • getNamePool

      public NamePool getNamePool()
      Get the target namepool to be used for stylesheets/queries and for source documents.
      Returns:
      the target name pool. If no NamePool has been specified explicitly, the default NamePool is returned.
      Since:
      8.4

    • setNamePool

      public void setNamePool(NamePool targetNamePool)
      Set the NamePool to be used for stylesheets/queries and for source documents.

      Using this method allows several Configurations to share the same NamePool. This was the normal default arrangement until Saxon 8.9, which changed the default so that each Configuration uses its own NamePool.

      Sharing a NamePool creates a potential bottleneck, since changes to the namepool are synchronized.

      Parameters:
      targetNamePool - The NamePool to be used.
      Since:
      8.4

    • getTypeHierarchy

      public TypeHierarchy getTypeHierarchy()

      Returns:
      the type hierarchy cache

    • getTypeChecker

      public TypeChecker getTypeChecker(boolean backwardsCompatible)
      Get an appropriate type-checker. The type-checker that is returned depends on whether backwards compatible (XPath 1.0) mode is enabled (which requires Saxon-PE or higher)
      Parameters:
      backwardsCompatible - set to true if XPath 1.0 compatibility mode is required
      Returns:
      a suitable TypeChecker

    • makeTypeAliasManager

      public TypeAliasManager makeTypeAliasManager()
      Make a TypeAliasManager appropriate to the type of Configuration
      Returns:
      a new TypeAliasManager

    • getDocumentNumberAllocator

      public DocumentNumberAllocator getDocumentNumberAllocator()
      Get the document number allocator.

      The document number allocator is used to allocate a unique number to each document built under this configuration. The document number forms the basis of all tests for node identity; it is therefore essential that when two documents are accessed in the same XPath expression, they have distinct document numbers. Normally this is ensured by building them under the same Configuration. Using this method together with setDocumentNumberAllocator(net.sf.saxon.tree.util.DocumentNumberAllocator), however, it is possible to have two different Configurations that share a single DocumentNumberAllocator

      Returns:
      the current DocumentNumberAllocator
      Since:
      9.0

    • setDocumentNumberAllocator

      public void setDocumentNumberAllocator(DocumentNumberAllocator allocator)
      Set the document number allocator.

      The document number allocator is used to allocate a unique number to each document built under this configuration. The document number forms the basis of all tests for node identity; it is therefore essential that when two documents are accessed in the same XPath expression, they have distinct document numbers. Normally this is ensured by building them under the same Configuration. Using this method together with getDocumentNumberAllocator(), however, it is possible to have two different Configurations that share a single DocumentNumberAllocator

      This method is for advanced applications only. Misuse of the method can cause problems with node identity. The method should not be used except while initializing a Configuration, and it should be used only to arrange for two different configurations to share the same DocumentNumberAllocators. In this case they should also share the same NamePool.

      Parameters:
      allocator - the DocumentNumberAllocator to be used
      Since:
      9.0

    • isCompatible

      public boolean isCompatible(Configuration other)
      Determine whether two Configurations are compatible. When queries, transformations, and path expressions are run, all the Configurations used to build the documents and to compile the queries and stylesheets must be compatible. Two Configurations are compatible if they share the same NamePool and the same DocumentNumberAllocator.
      Parameters:
      other - the other Configuration to be compared with this one
      Returns:
      true if the two configurations are compatible

    • getGlobalDocumentPool

      public DocumentPool getGlobalDocumentPool()
      Get the global document pool. This is used for documents preloaded during query or stylesheet compilation. The user application can preload documents into the global pool, where they will be found if any query or stylesheet requests the specified document using the doc() or document() function.
      Returns:
      the global document pool
      Since:
      9.1

    • isStripsAllWhiteSpace

      public boolean isStripsAllWhiteSpace()
      Determine whether whitespace-only text nodes are to be stripped unconditionally from source documents.
      Returns:
      true if the space stripping rules for the default parseOptions cause whitespace text nodes to be stripped from all elements.
      Since:
      8.4

    • getSourceParser

      public XMLReader getSourceParser() throws TransformerFactoryConfigurationError
      Get a parser for source documents. The parser is allocated from a pool if any are available from the pool: the client should ideally return the parser to the pool after use, so that it can be reused.

      This method is intended primarily for internal use.

      Returns:
      a parser, in which the namespace properties must be set as follows: namespaces=true; namespace-prefixes=false. The DTD validation feature of the parser will be set on or off depending on the setValidation(boolean) setting.
      Throws:
      TransformerFactoryConfigurationError - if a failure occurs configuring the parser for use.

    • reuseSourceParser

      public void reuseSourceParser(XMLReader parser)
      Return a source parser to the pool, for reuse
      Parameters:
      parser - The parser: the caller must not supply a parser that was obtained by any mechanism other than calling the getSourceParser() method. Must not be null.

      source - the Source to be used. This may be an AugmentedSource, allowing options to be specified for the way in which this document will be built. If an AugmentedSource is supplied then options set in the AugmentedSource take precedence over options set in the Configuration.

      If any error occurs reading or parsing the supplied Source, the error is notified to the ErrorListener registered with this Configuration.

      Returns:
      the constructed document as a TreeInfo
      Throws:
      XPathException - if any errors occur during document parsing or validation. Detailed errors occurring during schema validation will be written to the ErrorListener associated with the AugmentedSource, if supplied, or with the Configuration otherwise.
      Since:
      9.7; based on the original buildDocument(Source) method, but adapted to return the TreeInfo containing information about the constructed tree, including a reference to its root node.

    • buildDocumentTree

      public TreeInfo buildDocumentTree(Source source, ParseOptions parseOptions) throws XPathException
      Build a document, using specified options for parsing and building. This method always constructs a new tree, it never wraps an existing document (regardless of anything in the parseOptions)
      Parameters:
      source - the source of the document to be constructed. If this is an AugmentedSource, then any parser options contained in the AugmentedSource take precedence over options specified in the parseOptions argument.
      parseOptions - options for parsing and constructing the document. Any options that are not explicitly set in parseOptions default first to the values supplied in the source argument if it is an AugmentedSource, and then to the values set in this Configuration. The supplied parseOptions object is not modified.
      Returns:
      the constructed document as a TreeInfo
      Throws:
      XPathException - if parsing fails, or if the Source represents a node other than a document node
      Since:
      9.7; based on the original buildDocument(Source, ParseOptions) method, but adapted to return the TreeInfo containing information about the constructed tree, including a reference to its root node.

    • makeEmitter

      public Receiver makeEmitter(String eqName, Properties props) throws XPathException
      Load a named output emitter or SAX2 ContentHandler and check it is OK.
      Parameters:
      eqName - the EQName of the user-supplied ContentHandler (requested as a prefixed value of the method attribute in xsl:output, or anywhere that serialization parameters are allowed), encoded in EQName format as Q{uri}local
      props - the properties to be used in the case of a dynamically-loaded ContentHandler.
      Returns:
      a Receiver (despite the name, it is not required to be an Emitter)
      Throws:
      XPathException - if a failure occurs creating the Emitter

    • setConfigurationProperty

      public void setConfigurationProperty(String name, Object value)
      Set a property of the configuration. This method underpins the setAttribute() method of the TransformerFactory implementation, and is provided to enable setting of Configuration properties using URIs without instantiating a TransformerFactory: specifically, this may be useful when running XQuery, and it is also used by the Validator API.

      From Saxon 9.9, an alternative interface is available: setConfigurationProperty(Feature, Object). The new interface is more efficient because it avoids expensive string comparisons. The old interface is retained mainly for compatibility, and also because there are a few cases where it cannot easily be replaced, for example when using composite feature URIs to delegate configuration options to the XML parser.

      Parameters:
      name - the URI identifying the property to be set. See the class FeatureKeys for constants representing the property names that can be set.
      value - the value of the property. Note that boolean values may be supplied either as a Boolean, or as one of the strings "0", "1", "true", "false", "yes", "no", "on", or "off".
      Throws:
      IllegalArgumentException - if the property name is not recognized or if the value is not a valid value for the named property

    • setConfigurationProperty

      public <T> void setConfigurationProperty(Feature<T> feature, T value)
      Set a property of the configuration.

      This is the preferred way of setting configuration options from application code where it is known statically which feature is being set. Other methods are provided for use by wrapper APIs (such as the JAXP API) where the feature name is supplied dynamically as a string.

      Type Parameters:
      T - the type of value required for this particular feature
      Parameters:
      feature - the property to be set. See the class Feature for constants representing the property names that can be set.
      value - the value of the property. This must be of the correct type corresponding to the chosen Feature.
      Throws:
      IllegalArgumentException - if the property name is not recognized or if the value is not a valid value for the named property
