Constructor Details
- AbstractNodeTypePruningCallback
  
  public AbstractNodeTypePruningCallback(Set<Integer> nodeTypes)
  
  Creates an abstract pruned callback.
  
  Parameters:
  
  nodeTypes - the nodes to include in the traversal
- AbstractNodeTypePruningCallback
  
  public AbstractNodeTypePruningCallback(Set<Integer> nodeTypes, boolean include)
  
  Creates an abstract pruned callback.
  
  Parameters:
  
  nodeTypes - the nodes to include/exclude in the traversal
  
  include - whether to include or exclude the nodes in the traversal
Method Details
- 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 interface NodeTraversal.Callback
  
  Returns:
  
  whether the children of this node should be visited
