ClassKey

java.lang.Object
- com.fasterxml.jackson.jaxrs.util.ClassKey

All Implemented Interfaces:

java.lang.Comparable<ClassKey>
```
public final class ClassKey
extends java.lang.Object
implements java.lang.Comparable<ClassKey>
```
Efficient key class, used instead of using Class. The reason for having a separate key class instead of directly using Class as key is mostly to allow for redefining hashCode method -- for some strange reason, Class does not redefine Object.hashCode() and thus uses identity hash, which is pretty slow. This makes key access using Class unnecessarily slow.
Note: since class is not strictly immutable, caller must know what it is doing, if changing field values.
