public class AncestorStepPattern

extends StepPattern

Implements a match pattern step that tests an ancestor.

This class is based on an implementation from the Apache XML Project. In future releases the XML parser, XSLT processor, and associated classes will likely be updated to be based on a later version of the Apache implementations. Since Apache does not guarantee backwards compatibility between versions of their software, we cannot guarantee backwards compatibility of any of the classes contained in the weblogic.apache package or sub-packages.

Constructor Summary

AncestorStepPattern(int whatToShow)
Construct an AncestorStepPattern that doesn't test for node names.

AncestorStepPattern(int whatToShow, java.lang.String namespace, java.lang.String name)
Construct an AncestorStepPattern that tests for namespaces and node names.

Method Summary

protected void	calcScore() Static calc of match score.
XObject	execute(XPathContext xctxt) Overide the super method so that we can handle match patterns starting with a function such as id()/
XObject	executeRelativePathPattern(XPathContext xctxt) Execute the match pattern step relative to another step.
