Uses of OpenBitSet in org.apache.lucene.util

Subclasses of OpenBitSet in org.apache.lucene.util
`class` | `OpenBitSetDISI` OpenBitSet with added methods to bulk-update the bits from a `DocIdSetIterator`.

Methods in org.apache.lucene.util that return OpenBitSet
`OpenBitSet` | `OpenBitSet.clone()`

Methods in org.apache.lucene.util with parameters of type OpenBitSet
`void` | `OpenBitSet.and(OpenBitSet other)`
`void` | `OpenBitSet.andNot(OpenBitSet other)`
`static long` | `OpenBitSet.andNotCount(OpenBitSet a, OpenBitSet b)` Returns the popcount or cardinality of "a and not b" or "intersection(a, not(b))".
`void` | `OpenBitSet.intersect(OpenBitSet other)` this = this AND other
`static long` | `OpenBitSet.intersectionCount(OpenBitSet a, OpenBitSet b)` Returns the popcount or cardinality of the intersection of the two sets.
`boolean` | `OpenBitSet.intersects(OpenBitSet other)` returns true if the sets have any elements in common
`void` | `OpenBitSet.or(OpenBitSet other)`
`void` | `OpenBitSet.remove(OpenBitSet other)` Remove all elements set in other.
`void` | `OpenBitSet.union(OpenBitSet other)` this = this OR other
`static long` | `OpenBitSet.unionCount(OpenBitSet a, OpenBitSet b)` Returns the popcount or cardinality of the union of the two sets.
`void` | `OpenBitSet.xor(OpenBitSet other)` this = this XOR other
`static long` | `OpenBitSet.xorCount(OpenBitSet a, OpenBitSet b)` Returns the popcount or cardinality of the exclusive-or of the two sets.

Constructors in org.apache.lucene.util with parameters of type OpenBitSet
`OpenBitSetIterator(OpenBitSet obs)`
