shouldTraverse
public 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 interfaceNodeTraversal.Callback
- Returns:
- whether the children of this node should be visited
