`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.
