check
public static boolean check(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.
visitFunction
public boolean visitFunction(ExpressionOwner owner,
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.
visitPredicate
public boolean visitPredicate(ExpressionOwner owner,
Expression pred)
Visit a predicate within a location path. Note that there isn't a
proper unique component for predicates, and that the expression will
be called also for whatever type Expression is.
- visitPredicate in interface XPathVisitor
owner
- The owner of the expression, to which the expression can
be reset if rewriting takes place.pred
- The predicate object.
