public void visit(NodeTraversal t, Node n, Node parent)
NodeTraversal.Callback
Visits a node in postorder (after its children have been visited).
A node is visited only if all its parents should be traversed
(NodeTraversal.Callback.shouldTraverse(NodeTraversal, Node, Node)
).
Implementations can have side effects (e.g. modifying the parse tree).
