New Revision: 1222329
URL: http://svn.apache.org/viewvc?rev=1222329&view=rev
Log:
Update AbstractReplicatedMap and sub-classes to use generics
The key change is that it now implements Map<K,V> rather than extends
ConcurrentMap. There are several reasons for this:
- The interface is K,V but K,MapEntry<K,V> was placed in the extended
ConcurrentMap so generics simply couldn't work. Hence the switch from extending
ConcurrentMap to using a private ConcurrentMap instance
- The API contract for ConcurrentMap can't be met as currently written (and
without a lot of extra code) o switching to Map was the obvious approach.
