simplify
Simplify and validate.- Overrides:
simplifyin classFunctionCall- Parameters:
visitor- an expression visitor- Returns:
- the simplified expression
- Throws:
XPathException- if an error is discovered during expression rewriting
-
evaluateItem
Evaluate in a general context- Specified by:
evaluateItemin interfaceEvaluableItem- Overrides:
evaluateItemin classExpression- Parameters:
context- The context in which the expression is to be evaluated- Returns:
- the node or atomic value that results from evaluating the expression; or null to indicate that the result is an empty sequence
- Throws:
XPathException- if any dynamic error occurs evaluating the expression
