Method Detail

handles

public java.util.Vector handles()

Description copied from class: AbstractFigure

Returns the handles of a Figure that can be used to manipulate some of its attributes.

Specified by:

handles in interface Figure

Overrides:

handles in class RectangleFigure

Returns:

a Vector of handles

See Also:

Handle

rotate

public void rotate(double angle)

polygon

public java.awt.Polygon polygon()

Return the polygon describing the triangle

draw

public void draw(java.awt.Graphics g)

Description copied from class: AttributeFigure

Draws the figure in the given graphics. Draw is a template method calling drawBackground followed by drawFrame.

Specified by:

draw in interface Figure

Overrides:

draw in class AttributeFigure

Parameters:

g - the Graphics to draw into

connectionInsets

public java.awt.Insets connectionInsets()

Description copied from class: AbstractFigure

Returns the connection inset. The connection inset defines the area where the display box of a figure can't be connected. By default the entire display box can be connected.

Specified by:

connectionInsets in interface Figure

Overrides:

connectionInsets in class AbstractFigure

containsPoint

public boolean containsPoint(int x,
                             int y)

Description copied from class: AbstractFigure

Checks if a point is inside the figure.

Specified by:

containsPoint in interface Figure

Overrides:

containsPoint in class AbstractFigure

center

public java.awt.Point center()

Description copied from class: AbstractFigure

Gets the center of a figure. A convenice method that is rarely overridden.

Specified by:

center in interface Figure

Overrides:

center in class AbstractFigure

chop

public java.awt.Point chop(java.awt.Point p)

clone

public java.lang.Object clone()

Description copied from class: AbstractFigure

Clones a figure. Creates a clone by using the storable mechanism to flatten the Figure to stream followed by resurrecting it from the same stream.

Specified by:

clone in interface Figure

Overrides:

clone in class AbstractFigure

See Also:

Figure.clone()

write

public void write(StorableOutput dw)

Description copied from class: AttributeFigure

Stores the Figure to a StorableOutput.

Specified by:

write in interface Storable

Overrides:

write in class RectangleFigure

read

public void read(StorableInput dr)
          throws java.io.IOException

Description copied from class: AttributeFigure

Reads the Figure from a StorableInput.

Specified by:

read in interface Storable

Overrides:

read in class RectangleFigure

Throws:

java.io.IOException
