Class XUnresolvedVariableSimple

java.lang.Object

org.apache.xpath.Expression

org.apache.xpath.objects.XObject

org.apache.xalan.templates.XUnresolvedVariableSimple

All Implemented Interfaces:

Serializable, Cloneable, SourceLocator, ExpressionNode, XPathVisitable

public class XUnresolvedVariableSimple
extends XObject

This is the same as XUnresolvedVariable, but it assumes that the context is already set up. For use with psuedo variables. Also, it holds an Expression object, instead of an ElemVariable. It must only hold static context, since a single copy will be held in the template.
