public class TLcdXYArcBand extends ALcd2DEditableShape implements ILcd2DEditableArcBand, ILcdCache
This class provides an implementation of ILcd2DEditableArcBand in the cartesian space.

It implements ILcdCache, thus providing a cache to store expensive calculations, e.g. for painters, to store model-world transformations. The cache is cleared whenever the shape is modified.

This class is thread-safe for concurrent read-only access of its contents. For read-write access, external locking must be used. Such locking is typically done at the model level.
