    • create

      public static ConnectionSet create(GraphModel m, Object[] cells, boolean disconnect)
      Returns a connection set that represents the connection or disconnection of cells in model based on disconnect.

    • connect

      protected static void connect(ConnectionSet cs, Object edge, Object port, boolean source, boolean disconnect)
      Connect or disconnect edge from source and target in cs based on disconnect.

    • addConnections

      public void addConnections(CellView[] views)
      Adds the connections in views to the connection set.

    • connect

      public void connect(Object edge, Object source, Object target)
      Connect edge to source and target in the connection set. The previous connections between edge and its source and target are replaced in the set.

    • connect

      public void connect(Object edge, Object port, boolean source)
      Connect edge to port passed in. The source indicates if port is the source of edge object. The previous connections between edge and its source or target in the set is replaced.

    • disconnect

      public void disconnect(Object edge)
      Disconnect edge from source and target in the connection set. The previous connections between edge and its source and target are replaced in the set.

    • disconnect

      public void disconnect(Object edge, boolean source)
      Disconnect edge from port. source indicates if port is the source of edge. The previous connections between edge and its source or target in the set is replaced.

    • isEmpty

      public boolean isEmpty()
      Returns true if the connection set is empty.

    • size

      public int size()
      Returns the number of (edge, port)-pairs.

    • connections

      public Iterator connections()
      Returns an Iterator for the connections in this set.

    • getChangedEdges

      public Set getChangedEdges()
      Deprecated.
      Use getEdges
      Returns a Set for the edges in this connection set.

    • getPort

      public Object getPort(Object edge, boolean source)
      Returns the source or target of the specified edge in this connection set or null if the connection set contains no corresponding entry for the edge.

    • clone

      public ConnectionSet clone(Map map)
      Creates a new connection set based on this connection set, where the edges, and ports are mapped using map. If a port is not found, the old port is used. If both, the edge and the port are not in map, the entry is ignored.

      Note: Consequently, unselected edges are only reconnected at the first "paste" after a "cut", because in this case the ConnectionSet is not cloned.

    • getConnections

      public Set getConnections()
      Returns:
      the set of connections

    • getEdges

      public Set getEdges()
      Returns:
      the edges making us this connection set

    • setConnections

      public void setConnections(Set set)
      Parameters:
      set -

    • setEdges

      public void setEdges(Set set)
      Parameters:
      set -
