org.codehaus.jackson.map.type.ClassKey
- All Implemented Interfaces:
Comparable<ClassKey>
Key class, used as an efficient and accurate key
for locating per-class values, such as
JsonSerializer
s.
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.
