All Superinterfaces:

Collection<Position>, Iterable<Position>

All Known Implementing Classes:

IntersectionShape, Line, Pixel, Rectangle, SubtractionShape, UnionShape
```
public interface Shape
extends Collection<Position>
```
An interface for shapes that can be used with the PlayfieldModifier api.
A shape is a collection of Position objects thet represent filled in pixels of the shape. A Position may be present multiple time to cont the number of times the pixel should be painted.
