Traverser |
Node.traverse(Traverser.Order traversalOrder,
StopEvaluator stopEvaluator,
ReturnableEvaluator returnableEvaluator,

Direction direction)
Deprecated.
because of an unnatural and too tight coupling with
Node . Also because of the introduction of a new
traversal framework. The new way of doing traversals is by
creating a new TraversalDescription from
Traversal.traversal() , add rules and behaviors to it
and then calling
TraversalDescription.traverse(Node...) |
