Class ActorGraphModel.ExternalPortModel

  • All Implemented Interfaces:
    NodeModel
    Enclosing class:
    ActorGraphModel
    public class ActorGraphModel.ExternalPortModel
extends NamedObjNodeModel
    The model for ports that make external connections to this graph. These ports are always contained by the root of this graph model.

      • getDeleteNodeMoML

        public java.lang.String getDeleteNodeMoML​(java.lang.Object node)
        Return a MoML String that will delete the given node from the Ptolemy model. The MoML assumes a context that is the container of the port.
        Specified by:
        getDeleteNodeMoML in class NamedObjNodeModel
        Parameters:
        node - The node.
        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 a port contained in the root of this graph model.
        Returns:
        The root of this graph model.

      • inEdges

        public java.util.Iterator inEdges​(java.lang.Object node)
        Return an iterator over the edges coming into the given node. This method first ensures that there is a link object for every link. Then the iterator is constructed by removing any links that do not have the given node as head.
        Parameters:
        node - The node, which is assumed to be a port contained in the root of this graph model.
        Returns:
        An iterator of Link objects, all of which have the given node as their head.

      • outEdges

        public java.util.Iterator outEdges​(java.lang.Object node)
        Return an iterator over the edges coming out of the given node. This iterator is constructed by looping over all the relations that the port is connected to, and ensuring that there is a link object for every link. Then the iterator is constructed by removing any links that do not have the given node as tail.
        Parameters:
        node - The node, which is assumed to be a port contained in the root of this graph model.
        Returns:
        An iterator of Link objects, all of which have their tail as the given node.

      • removeNode

        public void removeNode​(java.lang.Object eventSource,
                       java.lang.Object node)
        Remove the given edge from the model.
        Specified by:
        removeNode in class NamedObjNodeModel
        Parameters:
        eventSource - The source of the event that will be dispatched, e.g. the view that made this call.
        node - The node.
