Examples of org.apache.lucene.search.CachingWrapperFilter

org.apache.lucene.search.CachingWrapperFilter
Wraps another filter's result and caches it. The purpose is to allow filters to simply filter, and then wrap with this class to add caching.

    if (qb != null)
    {
      cachedFilter = new QueryWrapperFilter(q);
    } else
    {
      cachedFilter = new CachingWrapperFilter(f);
    }


    filterCache.put(cacheKey, cachedFilter);
    return cachedFilter;
  }
