Subject: [PATCH] Improve Registry
|
|
|
|
Adds Registry#getKey(Object) which should be the
|
|
primary way people get the key for an object. Registry
|
|
items need to exist without having a key and so
|
|
getKey() methods on Keyed objects that have a registry
|
|
are marked as Deprecated or Obsolete.
