Class MutableModularGraphModel

  • All Implemented Interfaces:
    GraphModel, MutableGraphModel
    Direct Known Subclasses:
    BasicModularGraphModel

    public abstract class MutableModularGraphModel
    extends ModularGraphModel
    implements MutableGraphModel
    A modular implementation of the graph model, whereby users with heterogeneous graphs can implement the graph model interface by implementing the simple interfaces of Graph, Node, CompositeNode, and Edge.

        Construct an empty graph model whose root is the given semantic object.
    • Method Detail

      • acceptHead

        public boolean acceptHead​(java.lang.Object edge,
                                  java.lang.Object node)
        Return true if the head of the given edge can be attached to the given node.
        Specified by:
        acceptHead in interface MutableGraphModel
      • acceptTail

        public boolean acceptTail​(java.lang.Object edge,
                                  java.lang.Object node)
        Return true if the tail of the given edge can be attached to the given node.
        Specified by:
        acceptTail in interface MutableGraphModel
      • addNode

        public void addNode​(java.lang.Object eventSource,
                            java.lang.Object node,
                            java.lang.Object parent)
        Add a node to the given graph and notify listeners with a NODE_ADDED event.

        Specified by:
        addNode in interface MutableGraphModel
        Parameters:
        eventSource - The source of the event that will be dispatched, e.g. the view that made this call.
      • connectEdge

        public void connectEdge​(java.lang.Object eventSource,
                                java.lang.Object edge,
                                java.lang.Object tailNode,
                                java.lang.Object headNode)
        Connect the given edge to the given tail and head nodes, then dispatch events to the listeners.
        Specified by:
        connectEdge in interface MutableGraphModel
        Parameters:
        eventSource - The source of the event that will be dispatched, e.g. the view that made this call.
      • disconnectEdge

        public void disconnectEdge​(java.lang.Object eventSource,
                                   java.lang.Object edge)
        Disconnect an edge from its two endpoints and notify graph listeners with an EDGE_HEAD_CHANGED and an EDGE_TAIL_CHANGED event.
        Specified by:
        disconnectEdge in interface MutableGraphModel
        Parameters:
        eventSource - The source of the event that will be dispatched, e.g. the view that made this call.
      • getMutableEdgeModel

        public MutableEdgeModel getMutableEdgeModel​(java.lang.Object edge)
        Return the model for the given edge object, cast as a MutableEdgeModel. If the object is not an edge, then return null. This method assumes that the edge model for the given edge is mutable.
      • getMutableNodeModel

        public MutableNodeModel getMutableNodeModel​(java.lang.Object node)
        Return the node model for the given object, cast as a MutableNodeModel. If the object is not a node, then return null. This method assumes that the edge model for the given edge is mutable.
      • removeNode

        public void removeNode​(java.lang.Object eventSource,
                               java.lang.Object node)
        Delete a node from its parent graph and notify graph listeners with a NODE_REMOVED event. This first removes all the edges that are connected to the given node, or some subnode of that node, and then sets the parent of the node to null.
        Specified by:
        removeNode in interface MutableGraphModel
        Parameters:
        eventSource - The source of the event that will be dispatched, e.g. the view that made this call.
      • setEdgeHead

        public void setEdgeHead​(java.lang.Object eventSource,
                                java.lang.Object edge,
                                java.lang.Object head)
        Connect an edge to the given head node and notify listeners with an EDGE_HEAD_CHANGED event.
        Specified by:
        setEdgeHead in interface MutableGraphModel
        Parameters:
        eventSource - The source of the event that will be dispatched, e.g. the view that made this call.
      • setEdgeTail

        public void setEdgeTail​(java.lang.Object eventSource,
                                java.lang.Object edge,
                                java.lang.Object tail)
        Connect an edge to the given tail node and notify listeners with an EDGE_TAIL_CHANGED event.
        Specified by:
        setEdgeTail in interface MutableGraphModel
        Parameters:
        eventSource - The source of the event that will be dispatched, e.g. the view that made this call.
