Method Details
- visit
  
  public void visit(NodeTraversal unused, Node n, Node parent)
  
  Description copied from interface: NodeTraversal.Callback
  
  Visits a node in postorder (after its children). A node is visited in postorder iff NodeTraversal.Callback.shouldTraverse(NodeTraversal, Node, Node) returned true for its parent and itself. In particular, the root node is never visited in postorder.
  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.
  
  Specified by:
  
  visit in interface NodeTraversal.Callback
  
  Parameters:
  
  unused - The current traversal.
  
  n - The current node.
  
  parent - The parent of the current node.
- process
  
  public void process(Node externs, Node root)
  
  Description copied from interface: CompilerPass
  
  Process the JS with root node root. Can modify the contents of each Node tree
  
  Specified by:
  
  process in interface CompilerPass
  
  Parameters:
  
  externs - Top of external JS tree
  
  root - Top of JS tree
