 protected Connector fEnd

 public LineConnection()

Constructs a LineConnection. A connection figure has an arrow decoration at the start and end.

 public boolean canConnect()

Tests whether a figure can be a connection target. ConnectionFigures cannot be connected and return false.

Overrides:

canConnect in class AbstractFigure

 protected void basicMoveBy(int dx,
                            int dy)

Ensures that a connection is updated if the connection was moved.

Overrides:

basicMoveBy in class PolyLineFigure

 public void connectStart(Connector start)

Sets the start figure of the connection.

 public void connectEnd(Connector end)

Sets the end figure of the connection.

 public void disconnectStart()

Disconnects the start figure.

 public void disconnectEnd()

Disconnects the end figure.

 public boolean connectsSame(ConnectionFigure other)

Tests whether a connection connects the same figures as another ConnectionFigure.

 protected void handleDisconnect(Figure start,
                                 Figure end)

Handles the disconnection of a connection. Override this method to handle this event.

 protected void handleConnect(Figure start,
                              Figure end)

Handles the connection of a connection. Override this method to handle this event.
