Provides caching of {@link Filter}s themselves on the remote end of an RMI connection. The cache is keyed on Filter's hashCode(), so if it sees the same filter twice it will reuse the original version. NOTE: This does NOT cache the Filter bits, but rather the Filter itself. Thus, this works hand-in-hand with {@link CachingWrapperFilter} to keep both file Filter cache and the Filter bits on the remote end, close to the searcher. Usage: To cache a result you must do something like RemoteCachingWrapperFilter f = new RemoteCachingWrapperFilter(new CachingWrapperFilter(myFilter));
