Class SchemaManager

java.lang.Object
net.sf.saxon.s9api.SchemaManager
Direct Known Subclasses:
SchemaManagerImpl
public abstract class SchemaManager extends Object
The SchemaManager is used to load schema documents, and to set options for the way in which they are loaded. At present all the resulting schema components are held in a single pool owned by the Processor object.

To obtain a SchemaManager, use the method Processor.getSchemaManager().

In a schema-aware Processor there is exactly one SchemaManager (in a non-schema-aware Processor there is none).

The cache of compiled schema definitions can include only one schema component (for example a type, or an element declaration) with any given name. An attempt to compile two different schemas in the same namespace will usually therefore fail.

As soon as a type definition or element declaration is used for the first time in a validation episode, it is marked as being "sealed": this prevents subsequent modifications to the component. Examples of modifications that are thereby disallowed include adding to the substitution group of an existing element declaration, adding subtypes to an existing type, or redefining components using <xs:redefine>

    • setXsdVersion

      public abstract void setXsdVersion(String version)
      Set the version of XSD in use. The value must be "1.0" or "1.1". The default is currently "1.0", but this may change in a future release.
      Parameters:
      version - the version of the XSD specification/language: either "1.0" or "1.1".

    • getXsdVersion

      public abstract String getXsdVersion()
      Get the version of XSD in use. The value will be "1.0" or "1.1"
      Returns:
      the version of XSD in use.

    • setErrorListener

      @Deprecated public abstract void setErrorListener(ErrorListener listener)
      Deprecated.
      since 10.0. Use setErrorReporter(ErrorReporter).
      Set the ErrorListener to be used while loading and validating schema documents
      Parameters:
      listener - The error listener to be used. This is notified of all errors detected during the compilation. May be set to null to revert to the default ErrorListener.

    • getErrorListener

      @Deprecated public abstract ErrorListener getErrorListener()
      Deprecated.
      since 10.0. Use getErrorReporter()
      Get the ErrorListener being used while loading and validating schema documents
      Returns:
      listener The error listener in use. This is notified of all errors detected during the compilation. Returns null if no user-supplied ErrorListener has been set.

    • setErrorReporter

      public abstract void setErrorReporter(ErrorReporter reporter)

    • getErrorReporter

      public abstract ErrorReporter getErrorReporter()

    • setSchemaURIResolver

      public abstract void setSchemaURIResolver(SchemaURIResolver resolver)
      Set the SchemaURIResolver to be used during schema loading. This SchemaURIResolver, despite its name, is not used for resolving relative URIs against a base URI; it is used for dereferencing an absolute URI (after resolution) to return a Source representing the location where a schema document can be found.

      This SchemaURIResolver is used to dereference the URIs appearing in xs:import, xs:include, and xs:redefine declarations.

      Parameters:
      resolver - the SchemaURIResolver to be used during schema loading.

    • getSchemaURIResolver

      public abstract SchemaURIResolver getSchemaURIResolver()
      Get the SchemaURIResolver to be used during schema loading.
      Returns:
      the URIResolver used during stylesheet compilation. Returns null if no user-supplied URIResolver has been set.

    • load

      public abstract void load(Source source) throws SaxonApiException
      Load a schema document from a given Source. The schema components derived from this schema document are added to the cache of schema components maintained by this SchemaManager
      Parameters:
      source - the document containing the schema. The getSystemId() method applied to this Source must return a base URI suitable for resolving xs:include and xs:import directives. The document may be either a schema document in source XSD format, or a compiled schema in Saxon-defined SCM format (as produced using the -export option)
      Throws:
      SaxonApiException - if the schema document is not valid, or if its contents are inconsistent with the schema components already held by this SchemaManager.

    • load

      public void load(File file) throws SaxonApiException
      Load a schema document from a given File. The schema components derived from this schema document are added to the cache of schema components maintained by this SchemaManager
      Parameters:
      file - the document containing the schema. The getSystemId() method applied to this Source must return a base URI suitable for resolving xs:include and xs:import directives. The document may be either a schema document in source XSD format, or a compiled schema in Saxon-defined SCM format (as produced using the -export option)
      Throws:
      SaxonApiException - if the schema document is not valid, or if its contents are inconsistent with the schema components already held by this SchemaManager.
      Since:
      12.0

    • importComponents

      public abstract void importComponents(Source source) throws SaxonApiException
      Import a precompiled Schema Component Model from a given Source. The schema components derived from this schema document are added to the cache of schema components maintained by this SchemaManager
      Parameters:
      source - the XML file containing the schema component model, as generated by a previous call on exportComponents(net.sf.saxon.s9api.Destination)
      Throws:
      SaxonApiException - if a failure occurs loading the schema from the supplied source

    • exportComponents

      public abstract void exportComponents(Destination destination) throws SaxonApiException
      Export a precompiled Schema Component Model containing all the components (except built-in components) that have been loaded into this Processor.
      Parameters:
      destination - the destination to recieve the precompiled Schema Component Model in the form of an XML document
      Throws:
      SaxonApiException - if a failure occurs writing the schema components to the supplied destination

    • newSchemaValidator

      public abstract SchemaValidator newSchemaValidator()
      Create a SchemaValidator which can be used to validate instance documents against the schema held by this SchemaManager
      Returns:
      a new SchemaValidator
