From class org.apache.lucene.util.OpenBitSet

From class org.apache.lucene.search.DocIdSet

Public Constructors
	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.

Public Methods
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.
