Constructor Detail

DependencyFigure

public DependencyFigure()

Creates a new instance.

Method Detail

canConnect

public boolean canConnect(Figure start,
                          Figure end)

Checks if two figures can be connected. Implement this method to constrain the allowed connections between figures.

Specified by:

canConnect in interface ConnectionFigure

Overrides:

canConnect in class LineConnectionFigure

canConnect

public boolean canConnect(Figure start)

Description copied from interface: ConnectionFigure

Checks if this ConnectionFigure can be attached to the provided start figure. This is used to provide an early feedback to the user, when he/she creates a new connection.

Specified by:

canConnect in interface ConnectionFigure

Overrides:

canConnect in class LineConnectionFigure

handleDisconnect

protected void handleDisconnect(Figure start,
                                Figure end)

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

Overrides:

handleDisconnect in class LineConnectionFigure

handleConnect

protected void handleConnect(Figure start,
                             Figure end)

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

Overrides:

handleConnect in class LineConnectionFigure

clone

public DependencyFigure clone()

Description copied from interface: Figure

Returns a clone of the figure.

Specified by:

clone in interface Figure

Overrides:

clone in class LineConnectionFigure

getLayer

public int getLayer()

Description copied from interface: Figure

Gets the layer of the figure. The layer is used to determine the z-ordering of a figure inside of a drawing. Figures with a higher layer number are drawn after figures with a lower number. The z-order of figures within the same layer is determined by the sequence the figures were added to a drawing. Figures added later to a drawn after figures which have been added before. If a figure changes its layer, it must fire a FigureListener.figureChanged event to its figure listeners. FIXME - Replace int value by a Layer object.

Specified by:

getLayer in interface Figure

Overrides:

getLayer in class AbstractFigure

removeNotify

public void removeNotify(Drawing d)

Description copied from interface: Figure

Informs a figure, that it has been removed from the specified drawing. The figure must inform all FigureListeners that it has been removed.

Specified by:

removeNotify in interface Figure

Overrides:

removeNotify in class LineConnectionFigure
