/**
|
|
* The <code>Stroke</code> interface allows a
|
|
* {@link Graphics2D} object to obtain a {@link Shape} that is the
|
|
* decorated outline, or stylistic representation of the outline,
|
|
* of the specified <code>Shape</code>.
|
|
* Stroking a <code>Shape</code> is like tracing its outline with a
|
|
* marking pen of the appropriate size and shape.
|
|
* The area where the pen would place ink is the area enclosed by the
|
|
* outline <code>Shape</code>.
|
|
* <p>
|
|
* The methods of the <code>Graphics2D</code> interface that use the
|
|
* outline <code>Shape</code> returned by a <code>Stroke</code> object
|
|
* include <code>draw</code> and any other methods that are
|
|
* implemented in terms of that method, such as
|
|
* <code>drawLine</code>, <code>drawRect</code>,
|
|
* <code>drawRoundRect</code>, <code>drawOval</code>,
|
|
* <code>drawArc</code>, <code>drawPolyline</code>,
|
|
* and <code>drawPolygon</code>.
|
|
* <p>
|
|
* The objects of the classes implementing <code>Stroke</code>
|
|
* must be read-only because <code>Graphics2D</code> does not
|
|
* clone these objects either when they are set as an attribute
|
|
* with the <code>setStroke</code> method or when the
|
|
* <code>Graphics2D</code> object is itself cloned.
|
|
* If a <code>Stroke</code> object is modified after it is set in
|
|
* the <code>Graphics2D</code> context then the behavior
|
|
* of subsequent rendering would be undefined.
