Examples of prefuse.data.Tree.removeChild()

prefuse.data.Tree.removeChild()
Remove a node and its entire subtree rooted at the node from the tree. @param node the node id (node table row number) to remove @return true if the node and its subtree is successfully removed,false otherwise

        int size = tree.getNodeCount();
        Node r = tree.getRoot();
        Node c = r.getFirstChild();
        Edge e = c.getParentEdge();
        
        assertEquals(true, tree.removeChild(c));
        assertEquals(tree.getNodeCount(), size-1);
        assertEquals(false, c.isValid());
        assertEquals(false, e.isValid());
        assertEquals(true, r.getFirstChild() != c);
    }
