FILL

public static final boolean FILL

A key indicating the shape should be filled.

Constructor Detail

ShapeGraphicAttribute

public ShapeGraphicAttribute(Shape shape,
                             int alignment,
                             boolean stroke)

Constructs a ShapeGraphicAttribute for the specified Shape.

Parameters:

shape - the Shape to render. The Shape is rendered with its origin at the origin of this ShapeGraphicAttribute in the host TextLayout. This object maintains a reference to shape.

alignment - one of the alignments from this ShapeGraphicAttribute.

stroke - true if the Shape should be stroked; false if the Shape should be filled.

Method Detail

getAscent

public float getAscent()

Returns the ascent of this ShapeGraphicAttribute. The ascent of a ShapeGraphicAttribute is the positive distance from the origin of its Shape to the top of bounds of its Shape.

Overrides:

getAscent in class GraphicAttribute

Returns:

the ascent of this ShapeGraphicAttribute.

getDescent

public float getDescent()

Returns the descent of this ShapeGraphicAttribute. The descent of a ShapeGraphicAttribute is the distance from the origin of its Shape to the bottom of the bounds of its Shape.

Overrides:

getDescent in class GraphicAttribute

Returns:

the descent of this ShapeGraphicAttribute.

getAdvance

public float getAdvance()

Returns the advance of this ShapeGraphicAttribute. The advance of a ShapeGraphicAttribute is the distance from the origin of its Shape to the right side of the bounds of its Shape.

Overrides:

getAdvance in class GraphicAttribute

Returns:

the advance of this ShapeGraphicAttribute.

draw

public void draw(Graphics2D graphics,
                 float x,
                 float y)

Draws the graphic at the given location. The Shape is drawn with its origin at (x, y).

Overrides:

draw in class GraphicAttribute

Parameters:

graphics - the Graphics2D into which to draw the graphic

x, y - the user space coordinates where the graphic is drawn

getBounds

public Rectangle2D getBounds()

Returns a Rectangle2D that encloses all of the bits drawn by this ShapeGraphicAttribute relative to the rendering position. A graphic can be rendered beyond its origin, ascent, descent, or advance; but if it does, this method's implementation should indicate where the graphic is rendered.

Overrides:

getBounds in class GraphicAttribute

Returns:

a Rectangle2D that encloses all of the bits rendered by this ShapeGraphicAttribute.

hashCode

public int hashCode()

Returns a hashcode for this ShapeGraphicAttribute.

Overrides:

hashCode in class Object

Returns:

a hash code value for this ShapeGraphicAttribute.

equals

public boolean equals(Object rhs)

Compares this ShapeGraphicAttribute to the specified Object.

Overrides:

equals in class Object

Parameters:

rhs - the Object to compare for equality

Returns:

true if this ShapeGraphicAttribute equals rhs; false otherwise.

equals

public boolean equals(ShapeGraphicAttribute rhs)

Compares this ShapeGraphicAttribute to the specified ShapeGraphicAttribute.

Parameters:

rhs - the ShapeGraphicAttribute to compare for equality

Returns:

true if this ShapeGraphicAttribute equals rhs; false otherwise.
