Class XQueryExecutable


public class XQueryExecutable
extends java.lang.Object

An XQueryExecutable represents the compiled form of a query. To execute the query, it must first be loaded to form an XQueryEvaluator.

An XQueryExecutable is immutable, and therefore thread-safe. It is simplest to load a new XsltTransformer each time the stylesheet is to be run. However, the XsltTransformer is serially reusable within a single thread.

An XQueryExecutable is created by using one of the compile methods on the XQueryCompiler class.

Constructor Summary

XQueryExecutable(Processor processor, XQueryExpression exp)

Method Summary

XQueryExpression
getUnderlyingCompiledQuery()
Get the underlying implementation object representing the compiled stylesheet.
XQueryEvaluator
load()
Load the stylesheet to prepare it for execution.

Constructor Details

XQueryExecutable

protected XQueryExecutable(Processor processor,
                           XQueryExpression exp)

Method Details

getUnderlyingCompiledQuery

public XQueryExpression getUnderlyingCompiledQuery()
Get the underlying implementation object representing the compiled stylesheet. This provides an escape hatch into lower-level APIs. The object returned by this method may change from release to release.
Returns:
the underlying implementation of the compiled stylesheet

load

public XQueryEvaluator load()
Load the stylesheet to prepare it for execution.
Returns:
An XsltTransformer. The returned XsltTransformer can be used to set up the dynamic context for stylesheet evaluation, and to run the stylesheet.
