public final class ClassKey extends Object
Key class, used as an efficient and accurate key for locating per-class values fromMap
s.The reason for having a separate key class instead of directly using
Class
as key is mostly to allow for redefininghashCode
method -- for some strange reason,Class
does not redefineObject.hashCode()
and thus uses identity hash, which is pretty slow. This makes key access usingClass
unnecessarily slow.Note: since class is not strictly immutable, caller must know what it is doing, if changing field values.
