checkAbsolute
public boolean checkAbsolute(LocPathIterator path)
Process the LocPathIterator to see if it contains variables
or functions that may make it context dependent.
path - LocPathIterator that is assumed to be absolute, but needs checking.
- true if the path is confirmed to be absolute, false if it
may contain context dependencies.

Function func) Visit a function.
- visitFunction in interface XPathVisitor
owner - The owner of the expression, to which the expression can
be reset if rewriting takes place.func - The function reference object.
- true if the sub expressions should be traversed.
visitVariableRef
public boolean visitVariableRef(ExpressionOwner owner,
Variable var) Visit a variable reference.
- visitVariableRef in interface XPathVisitor
owner - The owner of the expression, to which the expression can
