Class Configuration

java.lang.Object
net.sf.saxon.Configuration
All Implemented Interfaces:
Serializable, SourceResolver

public class Configuration extends Object implements Serializable, SourceResolver
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-SA has a subclass of the Configuration class which provides the additional services needed for schema-aware processing. The com.saxonica.validate.SchemaAwareConfiguration 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.

8.4

    • makeConfiguration

      public static Configuration makeConfiguration(ClassLoader classLoader, String className)
      Factory method to create a Configuration. The resulting configuration will be schema-aware if Saxon-SA is installed and if a license is available; otherwise it will be non-schema-aware. Note that the license might not permit all processing options.
      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 schema aware configuration class. Defaults to "com.saxonica.validate.SchemaAwareConfiguration" 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, but despite the name of this method there is nothing that requires it to be schema-aware.
      Returns:
      a schema-aware configuration object if Saxon-SA can be loaded and a valid license is installed; otherwise, a non-schema-aware configuration object
      Since:
      9.0
    • init

      protected void init()
    • makeSchemaAwareConfiguration

      public static Configuration makeSchemaAwareConfiguration(ClassLoader classLoader, String className) throws RuntimeException
      Static method to instantiate a schema-aware configuration.

      On the .NET platform, this method should not be called unless it is known that the assembly saxon9sa.dll has already been loaded. This can be achieved by an appropriate call on Assembly.Load(): for an example, see the C# Configuration.cs class in the Saxon.Api namespace.

      This method fails if Saxon-SA cannot be loaded, but it does not fail if there is no license available. In that case it returns a schema-aware configuration object, but any attempt to use schema-aware processing will fail.

      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 schema aware configuration class. Defaults to "com.saxonica.validate.SchemaAwareConfiguration" 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, but despite the name of this method there is nothing that requires it to be schema-aware.
      Returns:
      the new SchemaAwareConfiguration
      Throws:
      RuntimeException - if the Saxon-SA product cannot be loaded
    • copy

      public Configuration copy()
      Copy an existing Configuration to create a new Configuration. This is a shallow copy. The new Configuration will share all the option settings of the old; it will also share the same NamePool, and the same DocumentNumberAllocator. If this configuration is schema-aware then the new one will also be schema-aware, and will share the same Schema manager and so on. (So any schema component loaded into one configuration will affect both).

      Note that creating a new SchemaAwareConfiguration using this method can be significantly cheaper than creating one from scratch, because it avoids the need to verify the Saxon-SA license key if this has already been done.

      Returns:
      a shallow copy of this Configuration
    • copyTo

      protected void copyTo(Configuration c)
    • 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:
      8.4
    • isSchemaAware

      public boolean isSchemaAware(int language)
      Determine if the configuration is schema-aware, for the given host language
      Parameters:
      language - the required host language: XSLT, XQUERY, or XML_SCHEMA
      Returns:
      true if the configuration is schema-aware
      Since:
      8.4
    • displayLicenseMessage

      public void displayLicenseMessage()
      Display a message about the license status
    • getHostLanguage

      public int getHostLanguage()
      Get the host language used in this configuration. The typical values are XSLT and XQUERY. The values XML_SCHEMA and JAVA_APPLICATION may also be encountered.

      This method is problematic because it is possible to run multiple transformations or queries within the same configuration. The method is therefore best avoided. Instead, use Container.getHostLanguage(). Internally its only use is in deciding (in Saxon-SA only) which error listener to use by default at compile time, and since the standard XSLT and XQuery listeners have no differences when used for static errors, the choice is immaterial.

      Returns:
      Configuration.XSLT or Configuration.XQUERY
    • setHostLanguage

      public void setHostLanguage(int hostLanguage)
      Set the host language used in this configuration. The possible values are XSLT and XQUERY.
      Parameters:
      hostLanguage - Configuration.XSLT or Configuration.XQUERY
    • getPlatform

      Get the Platform to be used for platform-dependent methods
      Returns:
      the platform to be used
    • setDynamicLoader

      public void setDynamicLoader(DynamicLoader dynamicLoader)
      Set the DynamicLoader to be used. By default an instance of DynamicLoader is used for all dynamic loading of Java classes. This method allows the actions of the standard DynamicLoader to be overridden
      Parameters:
      dynamicLoader - the DynamicLoader to be used by this Configuration
    • getDynamicLoader

      public DynamicLoader getDynamicLoader()
      Get the DynamicLoader used by this Configuration. By default the standard system-supplied dynamic loader is returned.
      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, ClassLoader classLoader) 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
      classLoader - The ClassLoader to be used to load the class, or null to use the ClassLoader selected by the DynamicLoader.
      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, ClassLoader classLoader) 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"
      classLoader - The ClassLoader to be used to load the class, or null to use the ClassLoader selected by the DynamicLoader.
      Returns:
      an instance of the class named, or null if it is not loadable.
      Throws:
      XPathException - if the class cannot be loaded.
    • getURIResolver

      public URIResolver getURIResolver()
      Get the URIResolver used in this configuration
      Returns:
      the URIResolver. If no URIResolver has been set explicitly, the default URIResolver is used.
      Since:
      8.4
    • setURIResolver

      public void setURIResolver(URIResolver resolver)
      Set the URIResolver to be used in this configuration. This will be used to resolve the URIs used statically (e.g. by xsl:include) and also the URIs used dynamically by functions such as document() and doc(). Note that the URIResolver does not resolve the URI in the sense of RFC 2396 (which is also the sense in which the resolve-uri() function uses the term): rather it dereferences an absolute URI to obtain an actual resource, which is returned as a Source object.
      Parameters:
      resolver - The URIResolver to be used.
      Since:
      8.4
    • setParameterizedURIResolver

      public void setParameterizedURIResolver()
      Set the URIResolver to a URI resolver that allows query parameters after the URI, and in the case of Saxon-SA, that inteprets the file extension .ptree
    • getSystemURIResolver

      public StandardURIResolver getSystemURIResolver()
      Get the system-defined URI Resolver. This is used when the user-defined URI resolver returns null as the result of the resolve() method
      Returns:
      the system-defined URI resolver
    • makeURIResolver

      public URIResolver makeURIResolver(String className) throws TransformerException
      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:
      TransformerException - if the requested class does not implement the javax.xml.transform.URIResolver interface
    • getErrorListener

      public ErrorListener getErrorListener()
      Get the ErrorListener used in this configuration. If no ErrorListener has been supplied explicitly, the default ErrorListener is used.

      Since:
      8.4
    • setErrorListener

      public void setErrorListener(ErrorListener listener)

    • 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

      public void setTraceListener(TraceListener traceListener)
      Set the TraceListener to be used for run-time tracing of instruction execution.

      Note: this method should not be used if the Configuration is multithreading. In that situation, use setCompileWithTracing(boolean) to force stylesheets and queries to be compiled with trace code enabled, and use Controller.addTraceListener(net.sf.saxon.trace.TraceListener) to supply a TraceListener at run time.

      Parameters:

    • setExtensionBinder

      public void setExtensionBinder(String scheme, FunctionLibrary binder)
      Set the FunctionLibrary used to bind calls on extension functions. This allows the rules for identifying extension functions to be customized (in principle, it would allow support for extension functions in other languages to be provided).

      When an application supplies its own FunctionLibrary for binding extension functions, this replaces the default binding mechanism for Java extension functions, namely JavaExtensionLibrary. It thus disables the function libraries for built-in Saxon extensions and for EXSLT extensions. It is possible to create a function library that adds to the existing mechanisms, rather than replacing them, by supplying as the FunctionLibrary a FunctionLibraryList that itself contains two FunctionLibrary objects: a JavaExtensionLibrary, and a user-written FunctionLibrary.

      Parameters:
      scheme - The URI scheme served by the extension binder. Currently this must be one of "java" or "clitype". On the Java platform, the only scheme currently supported is "java"; on the .NET platform, the "java" and "clitype" schemes coexist.
      binder - The FunctionLibrary object used to locate implementations of extension functions, based on their name and arity
      See Also:
    • getExtensionBinder

      public FunctionLibrary getExtensionBinder(String scheme)
      Get the FunctionLibrary used to bind calls on extension functions on the specified platform.

      This mechanism is for advanced users only, and the details are subject to change.

      Parameters:
      scheme - The URI scheme served by the extension binder. Currently this must be one of "java" or "clitype". On the Java platform, the only scheme currently supported is "java"; on the .NET platform, the "java" and "clitype" schemes coexist.
      Returns:
      the registered FunctionLibrary for extension functions if one has been registered; or the default FunctionLibrary for extension functions otherwise
    • getVendorFunctionLibrary

      public VendorFunctionLibrary getVendorFunctionLibrary()
      Get the FunctionLibrary used to bind calls on Saxon-defined extension functions.

      This method is intended for internal use only.

      Returns:
      the FunctionLibrary used for extension functions in the Saxon library.
    • setCollationURIResolver

      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
    • getCollationURIResolver

      public CollationURIResolver getCollationURIResolver()
      Get the collation URI resolver associated with this configuration. This will return the CollationURIResolver previously set using the setCollationURIResolver(net.sf.saxon.sort.CollationURIResolver) method; if this has not been called, it returns the system-defined collation URI resolver
      Returns:
      the registered CollationURIResolver
      Since:
      8.5
    • setCollectionURIResolver

      public void setCollectionURIResolver(CollectionURIResolver resolver)
      Set a CollectionURIResolver to be used to resolve collection URIs (that is, the URI supplied in a call to the collection() function).

      Collection URIs are always resolved at run-time, using the CollectionURIResolver in force at the time the collection() function is called.

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

    • isTiming

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

      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.

      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 to System.err.

      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

      Returns:
      true if such calls are permitted.
      Since:
      8.4
    • setAllowExternalFunctions

      public void setAllowExternalFunctions(boolean allowExternalFunctions)
      Determine whether calls to external Java functions are permitted. Allowing external function calls is potentially a security risk if the stylesheet or Query is untrusted, as it allows arbitrary Java methods to be invoked, which can examine or modify the contents of filestore and other resources on the machine where the query/stylesheet is executed.

      Setting the value to false disallows all of the following:

      • Calls to Java extension functions
      • Use of the XSLT system-property() function to access Java system properties
      • Use of a relative URI in the xsl:result-document instruction
      • Calls to XSLT extension instructions

      Note that this option does not disable use of the doc() function or similar functions to access the filestore of the machine where the transformation or query is running. That should be done using a user-supplied URIResolver

      Parameters:
      allowExternalFunctions - true if external function calls are to be permitted.
      Since:
      8.4
    • isTraceExternalFunctions

    • getExtensionFunctionFactory

      public ExtensionFunctionFactory getExtensionFunctionFactory(String scheme)
      Get an ExtensionFunctionFactory. This is used at compile time for generating the code that calls Java or .NET extension functions. It is possible to supply a user-defined ExtensionFunctionFactory to customize the way extension functions are bound.

      This mechanism is intended for advanced use only, and is subject to change.

      Parameters:
      scheme - - the extension function scheme. This must be one of "java" or "clitype", corresponding to the scheme name in the namespace URI of the extension function call
      Returns:
      the factory object registered to generate calls on extension functions, if one has been registered; if not, the default factory used by Saxon. The result will always be a JavaExtensionFunctionFactory in the case of the Java platform, or a net.sf.saxon.dotnet.DotNetExtensionFunctionFactory on the .NET platform
    • setExtensionFunctionFactory

      public void setExtensionFunctionFactory(String scheme, ExtensionFunctionFactory factory)
      Set an ExtensionFunctionFactory. This is used at compile time for generating the code that calls Java extension functions. It is possible to supply a user-defined ExtensionFunctionFactory to customize the way extension functions are called. The ExtensionFunctionFactory determines how external methods are called, but is not involved in binding the external method corresponding to a given function name or URI.

      This mechanism is intended for advanced use only, and is subject to change.

      Parameters:
      scheme - - the extension function scheme. This must be one of "java" or "clitype", corresponding to the scheme name in the namespace URI of the extension function call
      factory - The extension function factory. This must always be a JavaExtensionFunctionFactory for the "java" scheme, or a net.sf.saxon.dotnet.DotNetExtensionFunctionFactory for the "clitype" scheme

    • makeDocumentProjector

      public ProxyReceiver makeDocumentProjector(PathMap.PathMapRoot map)
      Create a document projector for a given path map. Document projection is available only in Saxon-SA, so the Saxon-B version of this method throws an exception
      Parameters:
      map - the path map used to control document projection
      Returns:
      a push filter that implements document projection
      Throws:

      public boolean isValidationWarnings()
      Determine whether schema validation failures on result documents are to be treated as fatal errors or as warnings.
      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 final TypeHierarchy getTypeHierarchy()

      Returns:
      the type hierarchy cache
    • 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.om.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.

    • 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.

      Parameters:
      source - A source object, typically the source supplied as the first argument to Transformer.transform(javax.xml.transform.Source, javax.xml.transform.Result) or similar methods.
      config - The Configuration. This provides the SourceResolver with access to configuration information; it also allows the SourceResolver to invoke the resolveSource() method on the Configuration object as a fallback implementation.
      Returns:
      a source object that Saxon knows how to process. This must be an instance of one of the classes StreamSource, SAXSource, DOMSource, AugmentedSource, NodeInfo, or PullSource. Return null if the Source object is not recognized

    • buildDocument

      public DocumentInfo buildDocument(Source source) throws XPathException
      Build a document tree, using options set on this Configuration and on the supplied source object. Options set on the source object override options set in the Configuration. The Source object must be one of the kinds of source recognized by Saxon, or a source that can be resolved using the registered SourceResolver.
      Parameters:
      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.

      A new tree will be built, using either the Tiny Tree or the Linked Tree implementation, except under the following circumstances:

      • The supplied object is a DocumentInfo. In this case a new tree will be built only if validation or whitespace stripping has been requested in the Configuration; otherwise the DocumentInfo will be returned unchanged.
      • The supplied object is an AugmentedSource wrapping a DocumentInfo. In this case a new tree will be built if wrap=no has been specified, if validation has been requested, or if whitespace stripping has been requested, either in the AugmentedSource or in the Configuration.
      • The supplied object is a DOMSource. In this case a new tree will be built if validation or whitespace stripping has been requested in the Configuration, or if the DOM Node is not a Document Node; in other cases the Document node of the DOMSource will be wrapped in a Saxon DocumentWrapper, except in the case where the DOM Document node is a DocumentOverNodeInfo, in which case the DocumentInfo that it wraps is returned.
      • The supplied object is an AugmentedSource wrapping a DOMSource. In this case a new tree will be built if wrap=no has been specified, if validation has been requested, or if whitespace stripping has been requested, either in the AugmentedSource or in the Configuration.

      The choice between a tiny tree and a linked tree is determined first be the properties of the AugmentedSource if that's what is supplied; otherwise by the properties of this Configuration.

      Returns:
      the document node of the constructed or wrapped document
      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:
      8.9. Modified in 9.0 to avoid copying a supplied document where this is not necessary.
    • makeEmitter

      XPathException
    • 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
