Field Summary

Fields inherited from class org.apache.lucene.util.OpenBitSet
`bits, wlen`

Constructor Summary
`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.

Constructor Detail

### OpenBitSetDISI

    public OpenBitSetDISI(DocIdSetIterator disi,
                          int maxSize)
                   throws IOException

  Construct an OpenBitSetDISI with its bits set from the doc ids of the given DocIdSetIterator. Also give a maximum size one larger than the largest doc id for which a bit may ever be set on this OpenBitSetDISI.

  Throws:
    `IOException`

### OpenBitSetDISI

    public 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 Detail

### inPlaceOr

    public void inPlaceOr(DocIdSetIterator disi)
                   throws IOException

  Perform an inplace OR with the doc ids from a given DocIdSetIterator, setting the bit for each such doc id. These doc ids should be smaller than the maximum size passed to the constructor.

  Throws:
    `IOException`

### inPlaceAnd

    public void inPlaceAnd(DocIdSetIterator disi)
                    throws IOException

  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. These doc ids should be smaller than the maximum size passed to the constructor.

  Throws:
    `IOException`

### inPlaceNot

    public void inPlaceNot(DocIdSetIterator disi)
                    throws IOException

  Perform an inplace NOT with the doc ids from a given DocIdSetIterator, clearing all the bits for each such doc id. These doc ids should be smaller than the maximum size passed to the constructor.

  Throws:
    `IOException`

### inPlaceXor

    public void inPlaceXor(DocIdSetIterator disi)
                    throws IOException

  Perform an inplace XOR with the doc ids from a given DocIdSetIterator, flipping all the bits for each such doc id. These doc ids should be smaller than the maximum size passed to the constructor.

  Throws:
    `IOException`
