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.

Specified by:
getAscent in class GraphicAttribute
Returns:
the ascent of this ShapeGraphicAttribute.
See Also:
GraphicAttribute.getBounds()

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.

Specified by:
getDescent in class GraphicAttribute
Returns:
the descent of this ShapeGraphicAttribute.
See Also:
GraphicAttribute.getBounds()

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.

Specified by:
getAdvance in class GraphicAttribute
Returns:
the advance of this ShapeGraphicAttribute.
See Also:
GraphicAttribute.getBounds()

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).

Specified by:
draw in class GraphicAttribute
Parameters:
graphics - the Graphics2D into which to draw the graphic

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.
See Also:
Object.equals(java.lang.Object), Hashtable

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.
See Also:
Object.hashCode(), Hashtable

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.
