isSchemaLanguageSupported

public boolean isSchemaLanguageSupported(java.lang.String language)

setErrorHandler

public void setErrorHandler(org.xml.sax.ErrorHandler errorHandler)

getErrorHandler

public org.xml.sax.ErrorHandler getErrorHandler()

setResourceResolver

public void setResourceResolver(org.w3c.dom.ls.LSResourceResolver lsResourceResolver)

getResourceResolver

public org.w3c.dom.ls.LSResourceResolver getResourceResolver()

newSchema

public javax.xml.validation.Schema newSchema(javax.xml.transform.Source[] sources)
                                      throws org.xml.sax.SAXException

Parses the specified source(s) as a schema and returns it as a schema.

The callee will read all the Sources and combine them into a single schema. The exact semantics of the combination depends on the schema language that this SchemaFactory object is created for.

When an ErrorHandler is set, the callee will report all the errors found in sources to the handler. If the handler throws an exception, it will abort the schema compilation and the same exception will be thrown from this method. Also, after an error is reported to a handler, the callee is allowed to abort the further processing by throwing it. If an error handler is not set, the callee will throw the first error it finds in the sources.

W3C XML Schema 1.0

The resulting schema contains components from the specified sources. The same result would be achieved if all these sources were imported, using appropriate values for schemaLocation and namespace, into a single schema document with a different targetNamespace and no components of its own, if the import elements were given in the same order as the sources. Section 4.2.3 of the XML Schema recommendation describes the options processors have in this regard. While a processor should be consistent in its treatment of JAXP schema sources and XML Schema imports, the behaviour between JAXP-compliant parsers may vary; in particular, parsers may choose to ignore all but the first <import> for a given namespace, regardless of information provided in schemaLocation.

If the parsed set of schemas includes error(s) as specified in the section 5.1 of the XML Schema spec, then the error must be reported to the ErrorHandler.

RELAX NG

For RELAX NG, this method must throw UnsupportedOperationException if schemas.length!=1.

Parameters:

sources - inputs to be parsed as schema documents. The Saxon implementation recognizes not only the standard SAXSource, StreamSource, and DOMSource, but also any implementation of NodeInfo

Returns:

Always return a non-null valid Schema object. Note that when an error has been reported, there is no guarantee that the returned Schema object is meaningful.

Throws:

org.xml.sax.SAXException - If an error is found during processing the specified inputs. When an ErrorHandler is set, errors are reported to there first. See setErrorHandler(ErrorHandler).

java.lang.NullPointerException - If the schemas parameter itself is null or any item in the array is null.

java.lang.IllegalArgumentException - If any item in the array is not recognized by this method.

newSchema

public javax.xml.validation.Schema newSchema()

Returns the Schema object containing all the schema components that have been loaded using the newSchema(javax.xml.transform.Source[]) method. If no schema components have been loaded, the schema can still be used to validate source documents provided that they specify the location of the required schema components using the xsi:schemaLocation attribute.

The returned Schema object assumes that if documents refer to the same URL in the schema location hints, they will always resolve to the same schema document. This asusmption allows implementations to reuse parsed results of schema documents so that multiple validations against the same schema will run faster.

Note that the use of schema location hints introduces a vulnerability to denial-of-service attacks.

Returns:

Always return a non-null valid Schema object.

getProperty

public java.lang.Object getProperty(java.lang.String name)
                             throws org.xml.sax.SAXNotRecognizedException,
                                    org.xml.sax.SAXNotSupportedException

Look up the value of a property.

The property name is any fully-qualified URI. It is possible for a SchemaFactory to recognize a property name but temporarily be unable to return its value.

SchemaFactorys are not required to recognize any specific property names.

In the Saxon implementation, the property names that are recognized are the same as the attribute names recognised by a TransformerFactory. These are listed as constant fields in the class FeatureKeys

Parameters:

name - The property name, which is a non-null fully-qualified URI.

Returns:

The current value of the property.

Throws:

org.xml.sax.SAXNotRecognizedException - If the property value can't be assigned or retrieved.

org.xml.sax.SAXNotSupportedException - When the XMLReader recognizes the property name but cannot determine its value at this time.

java.lang.NullPointerException - if the name parameter is null.

setProperty

public void setProperty(java.lang.String name,
                        java.lang.Object object)
                 throws org.xml.sax.SAXNotRecognizedException,
                        org.xml.sax.SAXNotSupportedException

Set the value of a property.

The property name is any fully-qualified URI. It is possible for a SchemaFactory to recognize a property name but to be unable to change the current value.

In the Saxon implementation, the property names that are recognized are the same as the attribute names recognised by a TransformerFactory. These are listed as constant fields in the class FeatureKeys

Parameters:

name - The property name, which is a non-null fully-qualified URI.

object - The requested value for the property.

Throws:

org.xml.sax.SAXNotRecognizedException - If the property value can't be assigned or retrieved.

org.xml.sax.SAXNotSupportedException - When the SchemaFactory recognizes the property name but cannot set the requested value.

java.lang.NullPointerException - if the name parameter is null.

getConfiguration

public SchemaAwareConfiguration getConfiguration()

Get the underlying Saxon Configuration object
