public abstract static class NodeTraversal.AbstractChangedScopeCallback extends NodeTraversal.AbstractPreOrderCallback

Callback that fires on changed scopes.

Constructor Details
- AbstractChangedScopeCallback
  
  public AbstractChangedScopeCallback()
Method Details
- shouldTraverse
  
  public final boolean shouldTraverse(NodeTraversal t, Node n, Node parent)
  
  Description copied from interface: NodeTraversal.Callback
  
  Visits a node in preorder (before its children) and decides whether the node and its children should be traversed.
  If this method returns true, the node will be visited by NodeTraversal.Callback.visit(NodeTraversal, Node, Node) in postorder and its children will be visited by both NodeTraversal.Callback.shouldTraverse(NodeTraversal, Node, Node) in preorder and by NodeTraversal.Callback.visit(NodeTraversal, Node, Node) in postorder.
  If this method returns false, the node will not be visited by NodeTraversal.Callback.visit(NodeTraversal, Node, Node) and its children will neither be visited by NodeTraversal.Callback.shouldTraverse(NodeTraversal, Node, Node) nor NodeTraversal.Callback.visit(NodeTraversal, Node, Node).
  Siblings are always visited left-to-right.
  Implementations can have side-effects (e.g. modify the parse tree). Removing the current node is legal, but removing or reordering nodes above the current node may cause nodes to be visited twice or not at all.
  
  Parameters:
  
  t - The current traversal.
  
  n - The current node.
  
  parent - The parent of the current node.
  
  Returns:
  
  whether the children of this node should be visited
