```
public abstract class ShapeImpl
extends Shape
```
Shape objects create a mapping of Property objects to indexes. The mapping of those indexes to an actual store is not part of Shape's role, but DynamicObject's. Shapes are immutable; adding or deleting a property yields a new Shape which links to the old one. This allows inline caching to simply check the identity of an object's Shape to determine if the cache is valid. There is one exception to this immutability, the transition map, but that is used simply to assure that an identical series of property additions and deletions will yield the same Shape object.
