ClassMap

```
public class ClassMap<T>
extends Object
```
Maps Class objects to values. A ClassMap is different from a regular Map in that get(c) does not only look to see if 'c' is a key in the Map, but also walks the up superclass and interface graph of 'c' to find matches. Derived matches of this sort are then "cached" in the registry so that matches are faster on future gets. This is a very useful class for Class based registries. Example: ClassMap m = new ClassMap(); m.put(Animal.class, "Animal"); m.put(Fox.class, "Fox"); m.Fox.class) --> "Fox" m.get(Dog.class) --> "Animal" (assuming Dog.class < Animal.class)
