Method Detail

set

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

Description copied from interface: Figure

Sets an attribute on the figure and calls attributeChanged on all registered FigureListeners if the attribute value has changed.

For efficiency reasons, the drawing is not automatically repainted. If you want the drawing to be repainted when the attribute is changed, you can either use key.set(figure, value); or

 figure.willChange();
 figure.set(...);
 figure.changed();
 

Specified by:

set in interface Figure

Overrides:

set in class AbstractCompositeFigure

See Also:

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

get

public <T> T get(AttributeKey<T> key)

Description copied from interface: Figure

Gets an attribute from the Figure.

Specified by:

get in interface Figure

Overrides:

get in class AbstractCompositeFigure

Returns:

Returns the attribute value. If the Figure does not have an attribute with the specified key, returns key.getDefaultValue().

See Also:

AttributeKey.get(org.jhotdraw.draw.Figure)

getAttributes

public java.util.Map<AttributeKey,java.lang.Object> getAttributes()

Description copied from interface: Figure

Returns a view to all attributes of this figure. By convention, an unmodifiable map is returned.

Specified by:

getAttributes in interface Figure

Overrides:

getAttributes in class AbstractCompositeFigure

setAttributes

public void setAttributes(java.util.Map<AttributeKey,java.lang.Object> map)

draw

public void draw(java.awt.Graphics2D g)

Description copied from interface: Figure

Draws the figure.

Specified by:

draw in interface Figure

Overrides:

draw in class AbstractCompositeFigure

Parameters:

g - The Graphics2D to draw to.

getBounds

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

Description copied from interface: Figure

Returns the untransformed logical bounds of the figure as a Rectangle.

The bounds are used by Handle objects for adjusting the figure and for aligning the figure on a grid.

Specified by:

getBounds in interface Figure

Overrides:

getBounds in class AbstractCompositeFigure

createHandles

public java.util.LinkedList<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 AbstractCompositeFigure

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

See Also:

Handle

isEmpty

public boolean isEmpty()

Description copied from interface: ODGFigure

Returns true, if this figure is empty for one of the following reasons:

• A group has no children
• A path has less than two points
• An ellipse or a rectangle has a width or a height of 0
• A text has no characters

Specified by:

isEmpty in interface ODGFigure

toString

public java.lang.String toString()

Overrides:

toString in class AbstractFigure

clone

public ODGGroupFigure 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 AbstractCompositeFigure
