- All Implemented Interfaces:
- Serializable
Deprecated. This package (all of contrib/remote) will be
removed in 4.0.
@Deprecated
public class RemoteCachingWrapperFilter
- extends org.apache.lucene.search.Filter
Provides caching of 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 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));
