| Method Summary | |
| public static boolean | check(LocPathIterator path)
Process the LocPathIterator to see if it contains variables
or functions that may make it context dependent.
Parameters:
path - LocPathIterator that is assumed to be absolute, but needs checking. | | public boolean | visitFunction(ExpressionOwner owner, Function func)
Visit a function.
Parameters:
owner - The owner of the expression, to which the expression can be reset if rewriting takes place.
Parameters:
func - The function reference object. | | public boolean | visitPredicate(ExpressionOwner owner, Expression pred)
Visit a predicate within a location path. |
| check | | public static boolean check(LocPathIterator path)(Code) | | Process the LocPathIterator to see if it contains variables
or functions that may make it context dependent.
Parameters:
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)(Code) | | Visit a function.
Parameters:
owner - The owner of the expression, to which the expression can be reset if rewriting takes place.
Parameters:
func - The function reference object. true if the sub expressions should be traversed. |
| visitPredicate | | public boolean visitPredicate(ExpressionOwner owner, Expression pred)(Code) | | 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.
Parameters:
owner - The owner of the expression, to which the expression can be reset if rewriting takes place.
Parameters:
pred - The predicate object. true if the sub expressions should be traversed. |
