Method Detail

onNode

boolean onNode(IComposite node)

Returns:

true if you wish the Composite walk to continue for child nodes in a PREORDER walk; POSTORDER walks are unaffected, of course, since by the time the parent node is visited, it is too late, as the children are visited first; there is no way to skip visiting subsequent children.
