Class StandardOutputResolver

java.lang.Object

net.sf.saxon.lib.StandardOutputResolver

All Implemented Interfaces:

OutputURIResolver

public class StandardOutputResolver
extends java.lang.Object
implements OutputURIResolver

This class defines the default OutputURIResolver. This is a counterpart to the JAXP URIResolver, but is used to map the URI of a secondary result document to a Result object which acts as the destination for the new document.

public StandardOutputResolver()

Method Detail

getInstance

public static StandardOutputResolver getInstance()

Get a singular instance

Returns:

the singleton instance of the class

newInstance

public StandardOutputResolver newInstance()

Get an instance of this OutputURIResolver class.

This method is called every time an xsl:result-document instruction is evaluated (with an href attribute). The resolve() and close() methods will be called on the returned instance.

This OutputURIResolver is stateless (that is, it retains no information between resolve() and close()), so the same instance can safely be returned each time. For a stateful OutputURIResolver, it must either take care to be thread-safe (handling multiple invocations of xsl:result-document concurrently), or it must return a fresh instance of itself for each call.

Specified by:

newInstance in interface OutputURIResolver

Returns:

a new instance of the class

resolve

public javax.xml.transform.Result resolve(java.lang.String href,
                                          java.lang.String base)
                                   throws XPathException

Resolve an output URI

Specified by:

resolve in interface OutputURIResolver

Parameters:

href - The relative URI of the output document. This corresponds to the href attribute of the xsl:result-document instruction.

base - The base URI that should be used. This is the base output URI, normally the URI of the principal output file.

Returns:

a Result object representing the destination for the XML document

Throws:

XPathException

createResult

protected javax.xml.transform.Result createResult(java.net.URI absoluteURI)
                                           throws XPathException,
                                                  java.io.IOException

Throws:

XPathException

java.io.IOException

close

public void close(javax.xml.transform.Result result)
           throws XPathException

Signal completion of the result document. This method is called by the system when the result document has been successfully written. It allows the resolver to perform tidy-up actions such as closing output streams, or firing off processes that take this result tree as input. Note that the OutputURIResolver is stateless, so the original href is supplied to identify the document that has been completed.

Specified by:

close in interface OutputURIResolver

Parameters:

result - The result object returned by the previous call of resolve()

Throws:

XPathException
