Class RemoteCachingWrapperFilter

java.lang.Object

org.apache.lucene.search.Filter

org.apache.lucene.search.RemoteCachingWrapperFilter

All Implemented Interfaces:

Serializable

Deprecated.

This package (all of contrib/remote) will be removed in 4.0.

@Deprecated
public class RemoteCachingWrapperFilter
extends Filter

Provides caching of Filters 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));
