Field Detail

IS_QUADRATIC

public static final AttributeKey<java.lang.Boolean> IS_QUADRATIC

If the attribute IS_QUADRATIC is set to true, all sides of the diamond have the same length.

Constructor Detail

DiamondFigure

public DiamondFigure()

Creates a new instance.

DiamondFigure

public DiamondFigure(double x,
                     double y,
                     double width,
                     double height)

Method Detail

drawFill

protected void drawFill(java.awt.Graphics2D g)

Description copied from class: AttributedFigure

This method is called by method draw() to draw the fill area of the figure. AttributedFigure configures the Graphics2D object with the FILL_COLOR attribute before calling this method. If the FILL_COLOR attribute is null, this method is not called.

Specified by:

drawFill in class AttributedFigure

drawStroke

protected void drawStroke(java.awt.Graphics2D g)

Description copied from class: AttributedFigure

This method is called by method draw() to draw the text of the figure . AttributedFigure configures the Graphics2D object with the TEXT_COLOR attribute before calling this method. If the TEXT_COLOR attribute is null, this method is not called.

Specified by:

drawStroke in class AttributedFigure

getBounds

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

Description copied from interface: Figure

Returns the logical bounds of the figure as a Rectangle. The logical bounds are used by some Handle objects for adjusting the figure.

getFigureDrawBounds

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

Overrides:

getFigureDrawBounds in class AttributedFigure

contains

public boolean contains(java.awt.geom.Point2D.Double p)

Checks if a Point2D.Double is inside the figure.

basicSetBounds

public void basicSetBounds(java.awt.geom.Point2D.Double anchor,
                           java.awt.geom.Point2D.Double lead)

Description copied from interface: Figure

Sets the logical bounds of the figure and of its decorator figure.

This is used by Tool's which create a new Figure and by Tool's which connect a Figure to another Figure.

This is a basic operation which does not fire events.

Parameters:

anchor - the start point of the bounds

lead - the end point of the bounds

See Also:

Figure.getBounds()

basicTransform

public void basicTransform(java.awt.geom.AffineTransform tx)

Moves the Figure to a new location.

Specified by:

basicTransform in interface Figure

Specified by:

basicTransform in class AbstractFigure

Parameters:

tx - the transformation matrix.

restoreTo

public void restoreTo(java.lang.Object geometry)

Description copied from interface: Figure

Restores the shape of the figure to a previously stored state.

getRestoreData

public java.lang.Object getRestoreData()

Description copied from interface: Figure

Gets data which can be used to restore the shape of the figure after a basicTransform has been applied to it.

See Also:

Figure.basicTransform(AffineTransform)

isQuadratic

public boolean isQuadratic()

setQuadratic

public void setQuadratic(boolean newValue)

findConnector

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

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

Specified by:

findConnector in interface Figure

Overrides:

findConnector in class AbstractFigure

Parameters:

p - the location of the connector.

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

See Also:

ChopDiamondConnector

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. Return null, if no compatible connector is available.

Specified by:

findCompatibleConnector in interface Figure

Overrides:

findCompatibleConnector in class AbstractFigure

clone

public DiamondFigure clone()

Description copied from interface: Figure

Returns a clone of the figure.

Specified by:

clone in interface Figure

Overrides:

clone in class AttributedFigure
