Class CachingWrapperFilter
java.lang.Object
org.apache.lucene.search.Filter
org.apache.lucene.search.CachingWrapperFilter
- All Implemented Interfaces:
- Serializable
- public class CachingWrapperFilter
- extends Filter
Wraps another filter's result and caches it. The caching
behavior is like QueryFilter
. The purpose is to allow
filters to simply filter, and then wrap with this class to add
caching, keeping the two concerns decoupled yet composable.
