com.fasterxml.jackson.jaxrs.xml.util.ClassKey

Efficient key class, used instead of using Class. The reason for having a separate key class instead of directly using {@link Class} as key is mostlyto allow for redefining hashCode method -- for some strange reason, {@link Class} does notredefine {@link Object#hashCode} and thus uses identityhash, which is pretty slow. This makes key access using {@link Class} unnecessarily slow.

Note: since class is not strictly immutable, caller must know what it is doing, if changing field values.

NOTE: cut'n pasted from 'databind' package for 2.0, to reduce tight coupling
