Class FixedBitSet
BitSet of fixed length (numBits), backed by accessible (GetBits()) long[], accessed with an int index, implementing GetBits() and DocIdSet. If you need to manage more than 2.1B bits, use Int64BitSet.

Methods
| Name | Description |
|---|---|
| And(DocIdSetIterator) | Does in-place AND of the bits provided by the iterator. |
| And(FixedBitSet) | this = this AND other |
| AndNot(DocIdSetIterator) | Does in-place AND NOT of the bits provided by the iterator. |
| AndNot(FixedBitSet) | this = this AND NOT other |
| AndNotCount(FixedBitSet, FixedBitSet) | Returns the popcount or cardinality of "a and not b" or "intersection(a, not(b))". Neither set is modified. |
| Bits2words(Int32) | Returns the number of 64 bit words it would take to hold |
| Cardinality() | Returns number of set bits. NOTE: this visits every
|
| Clear(Int32) | |
| Clear(Int32, Int32) | Clears a range of bits. |
| Clone() | |
| EnsureCapacity(FixedBitSet, Int32) | If the given FixedBitSet is large enough to hold
NOTE: the returned bitset reuses the underlying long[] of
the given |
| Equals(Object) | Returns |
| Flip(Int32, Int32) | Flips a range of bits |
| Get(Int32) | |
| GetAndClear(Int32) | |
| GetAndSet(Int32) | |
| GetBits() | Expert. |
| GetHashCode() | |
| GetIterator() | |
| IntersectionCount(FixedBitSet, FixedBitSet) | Returns the popcount or cardinality of the intersection of the two sets. Neither set is modified. |
| Intersects(FixedBitSet) | Returns true if the sets have any elements in common |
| NextSetBit(Int32) | Returns the index of the first set bit starting at the index specified. -1 is returned if there are no more set bits. |
| Or(DocIdSetIterator) | Does in-place OR of the bits provided by the iterator. |
| Or(FixedBitSet) | this = this OR other |
| PrevSetBit(Int32) | Returns the index of the last set bit before or on the index specified. -1 is returned if there are no more set bits. |
| Set(Int32) | |
| Set(Int32, Int32) | Sets a range of bits |
| UnionCount(FixedBitSet, FixedBitSet) | Returns the popcount or cardinality of the union of the two sets. Neither set is modified. |
| Xor(DocIdSetIterator) | Does in-place XOR of the bits provided by the iterator. |
| Xor(FixedBitSet) | this = this XOR other |
