NodeFigure

public NodeFigure()

Creates a new instance.

Method Detail

getConnectors

public java.util.Collection<Connector> getConnectors(ConnectionFigure prototype)

Description copied from interface: Figure

Returns all connectors of this Figure for the specified prototype of a ConnectionFigure.

This is used by connection tools and connection handles to visualize the connectors when the user is about to create a ConnectionFigure to this Figure.

Specified by:

getConnectors in interface Figure

Overrides:

getConnectors in class AbstractFigure

Parameters:

prototype - The prototype used to create a connection or null if unknown. This allows for specific connectors for different connection figures.

createHandles

public java.util.Collection<Handle> createHandles(int detailLevel)

Description copied from interface: Figure

Creates handles used to manipulate the figure.

Specified by:

createHandles in interface Figure

Overrides:

createHandles in class TextFigure

Parameters:

detailLevel - The detail level of the handles. Usually this is 0 for bounding box handles and 1 for point handles. The value -1 is used by the SelectAreaTracker and the HandleTracker to highlight figures, over which the mouse pointer is hovering.

Returns:

a Collection of handles

Handle

getFigureDrawingArea

public java.awt.geom.Rectangle2D.Double getFigureDrawingArea()

Description copied from class: TextFigure

Gets the drawing area without taking the decorator into account.

findConnector

public Connector findConnector(java.awt.geom.Point2D.Double p,
                               ConnectionFigure figure)

Description copied from class: AbstractFigure

Returns the Figures connector for the specified location. By default a ChopBoxConnector is returned.

Specified by:

findConnector in interface Figure

Overrides:

findConnector in class AbstractFigure

Parameters:

p - the location of the connector.

figure - The prototype used to create a connection or null if unknown. This allows for specific connectors for different connection figures.

See Also:

ChopRectangleConnector

findCompatibleConnector

public Connector findCompatibleConnector(Connector c,
                                         boolean isStart)

Description copied from interface: Figure

Gets a compatible connector. If the provided connector is part of this figure, return the connector. If the provided connector is part of another figure, return a connector with the same semantics for this figure. Returns null, if no compatible connector is available.

Specified by:

findCompatibleConnector in interface Figure

Overrides:

findCompatibleConnector in class AbstractFigure

clone

public NodeFigure 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 TextFigure

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

set

public <T> void set(AttributeKey<T> key,
                    T newValue)

Description copied from class: AbstractAttributedFigure

Sets an attribute of the figure. AttributeKey name and semantics are defined by the class implementing the figure interface.

Specified by:

set in interface Figure

Overrides:

set in class AbstractAttributedFigure

See Also:

AttributeKey.set(org.jhotdraw.draw.Figure, T)
