        Generate the moml to add a vertex to an exist link.
        Parameters:
        moml - The moml to add the vertex to the link.
        failmoml - The moml to undo these changed when something goes wrong.
        container - The container.
        oldLink - The link that will be replace by two new once and a vertex in between.

      • getDeleteEdgeMoML

        public java.lang.String getDeleteEdgeMoML​(java.lang.Object edge)
        Return a MoML String that will delete the given edge from the Ptolemy model.
        Parameters:
        edge - The edge.
        Returns:
        A valid MoML string.
      • getHead

        public java.lang.Object getHead​(java.lang.Object edge)

        setTail(Object, Object)
      • isDirected

        public boolean isDirected​(java.lang.Object edge)
        Return true if this edge is directed. In this model, none of edges are directed, so this always returns false.

                            java.lang.Object newLinkHead)
        Connect the given edge to the given head node. This class queues a new change request with the ptolemy model to make this modification.
        Specified by:
        setHead in interface MutableEdgeModel
        Parameters:
        edge - The edge, which is assumed to be a link.
        newLinkHead - The new head for the edge, which is assumed to be a location representing a port, a port or a vertex.

        getHead(Object)
      • setTail

        public void setTail​(java.lang.Object edge,
                            java.lang.Object newLinkTail)
        Connect the given edge to the given tail node. This class queues a new change request with the ptolemy model to make this modification.
        Specified by:
        setTail in interface MutableEdgeModel
        Parameters:
        edge - The edge, which is assumed to be a link.
