All Implemented Interfaces:
Serializable, SourceResolver
Direct Known Subclasses:
SchemaAwareConfiguration

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 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

Method Detail

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

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

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

public static Platform getPlatform()
Get the Platform to be used for platform-dependent methods

Returns:
the platform to be used

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.

Returns:
the ErrorListener.
Since:
8.4

setErrorListener

public void setErrorListener(ErrorListener listener)
Set the ErrorListener to be used in this configuration. The ErrorListener is informed of all static and dynamic errors detected, and can decide whether run-time warnings are to be treated as fatal.

Parameters:
listener - the ErrorListener to be used
Since:
8.4

reportFatalError

public void reportFatalError(XPathException err)
Report a fatal error

Parameters:

Since:
8.4

setTraceListener

public void setTraceListener(TraceListener traceListener)

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:
setExtensionFunctionFactory(java.lang.String, net.sf.saxon.functions.ExtensionFunctionFactory)

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

getCollectionURIResolver

public CollectionURIResolver getCollectionURIResolver()
Get the collection URI resolver associated with this configuration. This will return the CollectionURIResolver previously set using the setCollectionURIResolver(net.sf.saxon.CollectionURIResolver) method; if this has not been called, it returns the system-defined collection URI resolver

Returns:
the registered CollationURIResolver
Since:
8.5

setModuleURIResolver

public void setModuleURIResolver(ModuleURIResolver resolver)
Set a user-defined ModuleURIResolver for resolving URIs used in "import module" declarations in an XQuery prolog. This acts as the default value for the ModuleURIResolver in the StaticQueryContext, and may be overridden by a more specific ModuleURIResolver nominated as part of the StaticQueryContext.

Parameters:
resolver - the URI resolver for XQuery modules

setModuleURIResolver

public void setModuleURIResolver(String className)
                          throws TransformerException

Since:
8.4

setRecoveryPolicy

public void setRecoveryPolicy(int recoveryPolicy)
Determine how recoverable run-time errors are to be handled. This applies only if the standard ErrorListener is used. The recovery policy applies to errors classified in the XSLT 2.0 specification as recoverable dynamic errors, but only in those cases where Saxon provides a choice over how the error is handled: in some cases, Saxon makes the decision itself.

getSourceParserClass

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 Source object initialized with an appropriate implementation of org.xml.sax.XMLReader.

getStyleParserClass

public String getStyleParserClass()
Get the name of the class that will be instantiated to create an XML parser for parsing stylesheet modules.

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 Source object initialized with an appropriate implementation of org.xml.sax.XMLReader.

Returns:
the SerializerFactory in use
Since:
8.8

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.

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 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

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

Determine whether calls to external Java functions are permitted.

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:

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

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

Returns:
true if it is known that all nodes will be untyped

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:
UnsupportedOperationException - if this is not a schema-aware configuration, or if no Saxon-SA license is available

getSchemaValidationMode

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.

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.

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()
Get the TypeHierarchy: a cache holding type information

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. 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

isStripsAllWhiteSpace

getStripsWhiteSpace

public int getStripsWhiteSpace()
Set which kinds of whitespace-only text node should be stripped.

Returns:
kind the kind of whitespace-only text node that should be stripped when building a source tree. One of Whitespace.NONE (none), Whitespace.ALL (all), or Whitespace.IGNORABLE (element-content whitespace as defined in a DTD or schema)

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

reuseSourceParser

This method is intended for internal use only.

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. If this is null, then the classLoader used will be the first one available of: the classLoader registered with the Configuration using setClassLoader(java.lang.ClassLoader); the context class loader for the current thread; or failing that, the class loader invoked implicitly by a call of Class.forName() (which is the ClassLoader that was used to load the Configuration object itself).

Returns:
a StringCollator to implement a collation
Throws:
XPathException

setLazyConstructionMode

public void setLazyConstructionMode(boolean lazy)

Parameters:
lazy - true to switch lazy construction mode on, false to switch it off.

isLazyConstructionMode

public boolean isLazyConstructionMode()
Determine whether lazy construction mode is on or off. In lazy construction mode, element constructors are not evaluated until the content of the tree is required. Lazy construction mode is currently experimental and is therefore off by default.

Returns:
true if lazy construction mode is enabled

registerExternalObjectModel

public void registerExternalObjectModel(ExternalObjectModel model)
Register an external object model with this Configuration.

Parameters:

This method is intended for internal use only.

Returns:
a list of external object models supported. The members of the list are of type ExternalObjectModel

unravel

public NodeInfo unravel(Source source)
Get a NodeInfo corresponding to a DOM or other external Node, either by wrapping or unwrapping the external Node.

This method is intended for internal use.

Parameters:
source - A Source representing the wrapped or unwrapped external Node. This will typically be a DOMSource, but it may be a similar Source recognized by some other registered external object model.
Returns:
If the Source is a DOMSource and the underlying node is a wrapper around a Saxon NodeInfo, returns the wrapped Saxon NodeInfo. If the Source is a DOMSource and the undelying node is not such a wrapper, returns a new Saxon NodeInfo that wraps the DOM Node. If the Source is any other kind of source, it is offered to each registered external object model for similar treatment. The result is the NodeInfo object obtained by wrapping or unwrapping the supplied external node.
Throws:
IllegalArgumentException - if the source object is not of a recognized class. This method does not call the registered to resolve the Source.

setDOMLevel

public void setDOMLevel(int level)
Set the level of DOM interface to be used

Parameters:
level - the DOM level. Must be 2 or 3. By default Saxon assumes that DOM level 3 is available; this parameter can be set to the value 2 to indicate that Saxon should not use methods unless they are available in DOM level 2.

getDOMLevel

Get the level of DOM interface to be used

Returns:
the DOM level. Always 2 or 3.

makePipelineConfiguration

public PipelineConfiguration makePipelineConfiguration()

context - the XPath dynamic context
Returns:
the Saxon Configuration for a given XPath dynamic context

setSourceResolver

public void setSourceResolver(SourceResolver resolver)
Supply a SourceResolver. This is used for handling unknown implementations of the Source interface: a user-supplied SourceResolver can handle such Source objects and translate them to a kind of Source that Saxon understands.

Parameters:
resolver - the source resolver.

getSourceResolver

public SourceResolver getSourceResolver()
Get the current SourceResolver. If none has been supplied, a system-defined SourceResolver is returned.

Returns:
the current SourceResolver

resolveSource

public Source resolveSource(Source source,
                            Configuration config)
                     throws XPathException
Implement the SourceResolver interface

Specified by:
resolveSource in interface SourceResolver
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
Throws:
XPathException - if the Source object is recognized but cannot be processed

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.

controller - the Controller. Allows a local class loader to be used.
Returns:
a Receiver (despite the name, it is not required to be an Emitter)
Throws:
XPathException

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

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
Throws:
IllegalArgumentException - if the property name is not recognized
