## Class XUnresolvedVariableSimple

- java.lang.Object
- - org.apache.xpath.Expression
  - - org.apache.xpath.objects.XObject
    - - org.apache.xalan.templates.XUnresolvedVariableSimple

- All Implemented Interfaces:
    java.io.Serializable, java.lang.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.
