      • getDeleteNodeMoML

        public java.lang.String getDeleteNodeMoML​(java.lang.Object node)
        Return a MoML String that will delete the given node from the Ptolemy model.
        Specified by:
        getDeleteNodeMoML in class NamedObjNodeModel
        Parameters:
        node - The node to be deleted.
        Returns:
        A valid MoML string.

      • getParent

        public java.lang.Object getParent​(java.lang.Object node)
        Return the graph parent of the given node.
        Parameters:
        node - The node, which is assumed to be an instance of Locatable.
        Returns:
        The container of the location's container, which should be the root of the graph.

      • inEdges

        public java.util.Iterator inEdges​(java.lang.Object node)
        Return an iterator over the edges coming into the given node.
        Parameters:
        node - The node.
        Returns:
        A NullIterator, since no edges are attached to attributes.

      • outEdges

        public java.util.Iterator outEdges​(java.lang.Object node)
        Return an iterator over the edges coming out of the given node.
        Parameters:
        node - The node.
        Returns:
        A NullIterator, since no edges are attached to attributes.

      • removeNode

        public void removeNode​(java.lang.Object eventSource,
                       java.lang.Object node)
        Remove the given node from the model. The node is assumed to be an instance of Locatable belonging to an attribute. The removal is accomplished by queueing a change request with the container.
        Specified by:
        removeNode in class NamedObjNodeModel
        Parameters:
        eventSource - The source of the remove event (ignored).
        node - The node.
