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 postorder.
Implementations can have side effects (e.g. modifying the parse tree).

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).
