public class TLcdShapeList extends ALcdShapeList implements ILcdEditableShapeList
This class provides an implementation of ILcdShapeList. This implementation uses an array of the right size to store the list of shapes, which is memory efficient, but inefficient for adding and removing shapes.

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.
