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 transformation or query. 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.

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.

    • makeSchemaAwareConfiguration

      public static Configuration makeSchemaAwareConfiguration(ClassLoader classLoader) 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 saxon8sa.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.

      Parameters:
      classLoader - - the class loader to be used. If null, the context class loader for the current thread is used.
      Throws:
      RuntimeException - if the Saxon-SA product cannot be loaded or if no license key is available.
    • getProductTitle

      public String getProductTitle()

    • 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 Executable.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.

      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
    • 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

    • 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.

      8.4
    • setTraceListener

      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:
      traceListener - The TraceListener to be used.
      Since:
      8.4

      XPathException - if the requested class does not implement the net.sf.saxon.trace.TraceListener interface
    • setExtensionBinder

      public void setExtensionBinder(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:
      binder - The FunctionLibrary object used to locate implementations of extension functions, based on their name and arity
      See Also:
    • getExtensionBinder

      public FunctionLibrary getExtensionBinder()
      Get the FunctionLibrary used to bind calls on extension functions.

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

      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.

    • 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.
    • setModuleURIResolver

      public void setModuleURIResolver(String className) throws TransformerException
      Create and register an instance of a ModuleURIResolver with a specified class name. This will be used for resolving URIs in XQuery "import module" declarations, unless a more specific ModuleURIResolver has been nominated as part of the StaticQueryContext.
      Parameters:
      className - The fully-qualified name of the LocationHintResolver class
      Throws:
      TransformerException - if the requested class does not implement the net.sf.saxon.LocationHintResolver interface
    • getModuleURIResolver

      public ModuleURIResolver getModuleURIResolver()
      Get the user-defined ModuleURIResolver for resolving URIs used in "import module" declarations in the XQuery prolog; returns null if none has been explicitly set.

    • getRecoveryPolicy

      public int getRecoveryPolicy()
      Determine how recoverable run-time errors are to be handled. This applies only if the standard ErrorListener is used.
      Returns:
      the current recovery policy. The options are RECOVER_SILENTLY, RECOVER_WITH_WARNINGS, or DO_NOT_RECOVER.

      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.
      Parameters:
      recoveryPolicy - the recovery policy to be used. The options are RECOVER_SILENTLY, RECOVER_WITH_WARNINGS, or DO_NOT_RECOVER.

      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.

    • 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.

    • 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
      Parameters:

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

      Normally all transformations and queries run under a single Java VM share the same NamePool. This creates a potential bottleneck, since changes to the namepool are synchronized. It is possible therefore to allocate a distinct NamePool to each Configuration. This requires considerable care and should only be done when the default arrangement is found to cause problems. There is a basic rule to follow: any compiled stylesheet or query must use the same NamePool as its source and result documents.

      Parameters:
      targetNamePool - The NamePool to be used.
