        Builds the parents of node up to and including the root node, where the original node is the last element in the returned array. The length of the returned array gives the node's depth in the tree.
        Parameters:
        aNode - the TreeNode to get the path for

      • getPathToRoot

        protected java.lang.Object[] getPathToRoot​(T aNode,
                                           int depth)
        Builds the parents of node up to and including the root node, where the original node is the last element in the returned array. The length of the returned array gives the node's depth in the tree.
        Parameters:
        aNode - the TreeNode to get the path for
        depth - an int giving the number of steps already taken towards the root (on recursive calls), used to size the returned array
        Returns:
        an array of TreeNodes giving the path from the root to the specified node
