Functions

andNotCount

fun andNotCount(a: FixedBitSet, b: FixedBitSet): Long

Returns the popcount or cardinality of "a and not b" or "intersection(a, not(b))". Neither set is modified.

andRange

fun andRange(source: FixedBitSet, sourceFrom: Int, dest: FixedBitSet, destFrom: Int, length: Int)

And length bits starting at sourceFrom from source into dest starting at destFrom.

bits2words

fun bits2words(numBits: Int): Int

returns the number of 64 bit words it would take to hold numBits

copyOf

fun copyOf(bits: Bits): FixedBitSet

Make a copy of the given bits.

ensureCapacity

fun ensureCapacity(bits: FixedBitSet, numBits: Int): FixedBitSet

If the given FixedBitSet is large enough to hold numBits+1, returns the given bits, otherwise returns a new FixedBitSet which can hold the requested number of bits.

intersectionCount

fun intersectionCount(a: FixedBitSet, b: FixedBitSet): Long

Returns the popcount or cardinality of the intersection of the two sets. Neither set is modified.

orRange

fun orRange(source: FixedBitSet, sourceFrom: Int, dest: FixedBitSet, destFrom: Int, length: Int)

Or length bits starting at sourceFrom from source into dest starting at destFrom.

unionCount

fun unionCount(a: FixedBitSet, b: FixedBitSet): Long

Returns the popcount or cardinality of the union of the two sets. Neither set is modified.
