Class SaxonProcessor

java.lang.Object

org.trancecode.xml.saxon.SaxonProcessor

All Implemented Interfaces:

com.google.common.base.Function<net.sf.saxon.s9api.XdmNode,net.sf.saxon.s9api.XdmNode>

public final class SaxonProcessor
extends Object
implements com.google.common.base.Function<net.sf.saxon.s9api.XdmNode,net.sf.saxon.s9api.XdmNode>

A processor that walks over s9api documents and calls a delegate on each encountered node, possibly returning a result document.

Before each document processing, the processor initializes a SaxonBuilder that is passed to the delegate to create the result tree.

The processor is thread-safe (i.e. can process independent documents concurrently) if and only if the delegate SaxonProcessorDelegate is thread-safe.

public SaxonProcessor(net.sf.saxon.s9api.Processor processor,
              SaxonProcessorDelegate delegate)

Creates a new document processor using the given delegate.

Parameters:

processor - The Saxon processor used to initialize a new SaxonBuilder for each new document processing

delegate - The delegate that will be called by this processor

Method Detail

apply

public net.sf.saxon.s9api.XdmNode apply(net.sf.saxon.s9api.XdmNode node)

Walks over the given s9api document and return the result of the processing.

For each visited node, the processing is delegated to the internal SaxonProcessorDelegate.

A shared SaxonBuilder instance is created and can be used by the delegate to build the returned result tree.

Specified by:

apply in interface com.google.common.base.Function<net.sf.saxon.s9api.XdmNode,net.sf.saxon.s9api.XdmNode>

Parameters:

node - A s9api document node to process

Returns:

The tree built while processing the document
