public NodeTraversal.AbstractPostOrderCallback()
shouldTraverse
public final boolean shouldTraverse(NodeTraversal nodeTraversal,
Node n,
Node parent)
- Description copied from interface:
NodeTraversal.Callback
Visits a node in pre order (before visiting its children) and decides
whether this node's children should be traversed. If children are
traversed, they will be visited by
NodeTraversal.Callback.visit(NodeTraversal, Node, Node) in post order.
Implementations can have side effects (e.g. modifying the parse
tree).
- Specified by:
shouldTraverse in interface NodeTraversal.Callback
- Returns:
- whether the children of this node should be visited
