Interface GraphicalElement

All Known Implementing Classes:
BasicGraphicalElement, GraphicalComposite

public interface GraphicalElement

Interface all graphical elements have to implement. Together with the marker interface Renderer it realizes the Anticyclic Visitor Pattern, a variant of the GoF Visitor Pattern. This allows not only to extend JCCKit with new renderers but also with new types of GraphicalElements without touching existing code.
