OpenBitSetDISI(DocIdSetIterator disi,
int maxSize)
Construct an OpenBitSetDISI with its bits set from the doc ids of the given DocIdSetIterator. |
|
OpenBitSetDISI(int maxSize)
Construct an OpenBitSetDISI with no bits set, and a given maximum size one larger than the largest doc id for which a bit may ever be set on this OpenBitSetDISI. |
Method Summary | |
---|---|
void |
inPlaceAnd(DocIdSetIterator disi)
Perform an inplace AND with the doc ids from a given DocIdSetIterator, leaving only the bits set for which the doc ids are in common. |
void |
inPlaceNot(DocIdSetIterator disi)
Perform an inplace NOT with the doc ids from a given DocIdSetIterator, clearing all the bits for each such doc id. |
void |
inPlaceOr(DocIdSetIterator disi)
Perform an inplace OR with the doc ids from a given DocIdSetIterator, setting the bit for each such doc id. |
void |
inPlaceXor(DocIdSetIterator disi)
Perform an inplace XOR with the doc ids from a given DocIdSetIterator, flipping all the bits for each such doc id. |
