DependencyFigure

public DependencyFigure()

Creates a new instance.

Method Detail

canConnect

public boolean canConnect(Connector start,
                          Connector 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(Connector start)

Description copied from interface: ConnectionFigure

Checks if this ConnectionFigure can be connect to the specified Connector. 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

clone

public DependencyFigure clone()

Description copied from interface: Figure

Returns a clone of the figure, with clones of all aggregated figures, such as children and decorators. The cloned figure does not clone the list of FigureListeners from its original.

Specified by:

clone in interface Figure

Overrides:

clone in class LineConnectionFigure

getLayer

public int getLayer()

Description copied from class: AbstractFigure

AbstractFigure always returns 0. Override this method if your figure needs to be on a different layer.

Specified by:

getLayer in interface Figure

Overrides:

getLayer in class AbstractFigure

removeNotify

public void removeNotify(Drawing d)

Description copied from class: LineConnectionFigure

This method is invoked, when the Figure is being removed from a Drawing. This method invokes handleDisconnect, if the Figure is connected.

Specified by:

removeNotify in interface Figure

Overrides:

removeNotify in class LineConnectionFigure

See Also:

LineConnectionFigure.handleDisconnect(org.jhotdraw.draw.connector.Connector, org.jhotdraw.draw.connector.Connector)
