java.lang.Object net.sf.saxon.Configuration
public class Configuration
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.

public static Configuration makeConfiguration(ClassLoader classLoader, String className)
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.
public static Configuration makeSchemaAwareConfiguration(ClassLoader classLoader, String className) throws RuntimeException
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.
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.
RuntimeException
- if the Saxon-SA product cannot be loadedpublic Configuration copy()
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.

public boolean isSchemaAware(int language)

public void displayLicenseMessage()
public int getHostLanguage()
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.

use setCompileWithTracing(boolean)

implement the net.sf.saxon.trace.TraceListener interfacepublic void setExtensionBinder(String scheme, FunctionLibrary binder)
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.
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 aritysetExtensionFunctionFactory(java.lang.String, net.sf.saxon.functions.ExtensionFunctionFactory)

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

This method is intended for internal use only.

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.

public NamePool getNamePool()
public void setNamePool(NamePool targetNamePool)
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.

public DocumentNumberAllocator getDocumentNumberAllocator()
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
public void setDocumentNumberAllocator(DocumentNumberAllocator 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

Normally this is ensured by building them under the same Configuration. Using this method together with

, 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.
