Public Member Functions | |
| virtual | ~Filter () |
| virtual Filter * | clone () const =0 |
| virtual lucene::util::BitSet * | bits (lucene::index::IndexReader *reader)=0 |
| Returns a BitSet with true for documents which should be permitted in search results, and false for those that should not. | |
| virtual bool | shouldDeleteBitSet (const lucene::util::BitSet *bs) const |
| Because of the problem of cached bitsets with the CachingWrapperFilter, CLucene has no way of knowing whether to delete the bitset returned from bits(). | |

Returns a BitSet with true for documents which should be permitted in search results, and false for those that should not.
MEMORY: read shouldDeleteBitSet
Implemented in lucene::search::AbstractCachingFilter, lucene::search::ChainedFilter, lucene::search::DateFilter, lucene::search::PrefixFilter, lucene::search::QueryFilter, lucene::search::RangeFilter, and lucene::search::WildcardFilter.
| virtual bool lucene::search::Filter::shouldDeleteBitSet | ( | const lucene::util::BitSet * | bs | ) | const [inline, virtual] |
Because of the problem of cached bitsets with the CachingWrapperFilter, CLucene has no way of knowing whether to delete the bitset returned from bits().
To properly clean memory from bits(), pass the bitset to this function. The Filter should be deleted if this function returns true.
Reimplemented in lucene::search::AbstractCachingFilter.
