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 postorder.

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
