    • Method Detail

      • applyDecoration

        public Node applyDecoration​(Node targetNode)
        This method decorates the given target node with the relevant decorations, returning any 'decoration node' that needs to be added to the scenegraph (although this can be null). When the returned Node is null, this indicates that the decoration will be handled internally by the decoration (which is preferred, as the default implementation is not ideal in most circumstances).

        When the boolean parameter is false, this method removes the decoration from the given target node, always returning null.

        Specified by:
        applyDecoration in class Decoration
        Parameters:
        targetNode - The node to decorate.
        Returns:
        The decoration, but null is a valid return value.
      • removeDecoration

        public void removeDecoration​(Node targetNode)
        This method removes the decoration from the given target node.
        Specified by:
        removeDecoration in class Decoration
        Parameters:
        targetNode - The node to undecorate.
