Class ConstantNamespaceContext

java.lang.Object

org.conqat.lib.commons.xml.ConstantNamespaceContext

All Implemented Interfaces:

javax.xml.namespace.NamespaceContext

public class ConstantNamespaceContext
extends java.lang.Object
implements javax.xml.namespace.NamespaceContext

A minimalistic implementation of NamespaceContext to be used with XPath. Method getNamespaceURI(String) always returns the string provided to the constructor. All other methods throw UnsupportedOperationExceptions. These methods are not needed for XPath resolution.

Implementation is inspired by snippet on http://www.ibm.com/developerworks/library/x-javaxpathapi.html.
