public class AnnotationPainter extends Object implements IPainter, PaintListener, IAnnotationModelListener, IAnnotationModelListenerExtension, ITextPresentationListener
The annotation painter can be configured with drawing strategies. A drawing strategy defines the visual presentation of a particular type of annotation decoration.
Clients usually instantiate and configure objects of this class.
