public final boolean shouldTraverse(NodeTraversal nodeTraversal,
                                    Node n,

```
    Description copied from interface: NodeTraversal.Callback
    
    Visits a node in preorder (before its children) and decides whether its children should be traversed. If the children should be traversed, they will be visited by NodeTraversal.Callback.shouldTraverse(NodeTraversal, Node, Node) in preorder and by NodeTraversal.Callback.visit(NodeTraversal, Node, Node) 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:
    
    shouldTraverse in interface NodeTraversal.Callback
    
    Parameters:
    
    nodeTraversal - The current traversal.
    
    n - The current node.
    
    parent - The parent of the current node.
    
    Returns:
    
    whether the children of this node should be visited
