Method Detail

setAttributeEnabled

public void setAttributeEnabled(AttributeKey key,
                                boolean b)

isAttributeEnabled

public boolean isAttributeEnabled(AttributeKey key)

setAttributes

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

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

getAttributesRestoreData

public java.lang.Object getAttributesRestoreData()

Description copied from interface: Figure

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

Specified by:

getAttributesRestoreData in interface Figure

restoreAttributesTo

public void restoreAttributesTo(java.lang.Object restoreData)

Description copied from interface: Figure

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

Specified by:

restoreAttributesTo in interface Figure

set

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

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

See Also:

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

get

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

Gets an attribute from the figure.

Specified by:

get in interface Figure

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)

draw

public void draw(java.awt.Graphics2D g)

Description copied from interface: Figure

Draws the figure.

Specified by:

draw in interface Figure

Parameters:

g - The Graphics2D to draw to.

getStroke

public java.awt.Stroke getStroke()

getStrokeMiterLimitFactor

public double getStrokeMiterLimitFactor()

getDrawingArea

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

Description copied from interface: Figure

Returns the drawing area of the figure as a Rectangle.

The drawing area is used to inform DrawingView about the area that is needed to draw this figure.

The drawing area needs to be large enough, to take line width, line caps and other decorations into account that exceed the bounds of the Figure.

Specified by:

getDrawingArea in interface Figure

drawFill

protected abstract void drawFill(java.awt.Graphics2D g)

This method is called by method draw() to draw the fill area of the figure. AbstractAttributedFigure 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.

drawStroke

protected abstract void drawStroke(java.awt.Graphics2D g)

This method is called by method draw() to draw the text of the figure . AbstractAttributedFigure 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.

drawText

protected void drawText(java.awt.Graphics2D g)

clone

public AbstractAttributedFigure 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 AbstractFigure

writeAttributes

protected void writeAttributes(DOMOutput out)
                        throws java.io.IOException

Throws:

java.io.IOException

readAttributes

protected void readAttributes(DOMInput in)
                       throws java.io.IOException

Throws:

java.io.IOException

getAttributeKey

protected AttributeKey getAttributeKey(java.lang.String name)

applyAttributesTo

protected void applyAttributesTo(Figure that)

Applies all attributes of this figure to that figure.

write

public void write(DOMOutput out)
           throws java.io.IOException

Specified by:

write in interface DOMStorable

Throws:

java.io.IOException

public void read(DOMInput in)
          throws java.io.IOException

Specified by:

read in interface DOMStorable

Throws:
