Examples of org.codehaus.jackson.map.type.ClassKey

org.codehaus.jackson.map.type.ClassKey
Key class, used as an efficient and accurate key for locating per-class values, such as {@link org.codehaus.jackson.map.JsonSerializer}s.
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.
