boolean assertIsValid()

isBitSet

boolean isBitSet(int bitIndex)

Forwards to BitUtil.isBitSet(long[], int, int).

countBits

int countBits()

Forwards to BitUtil.countBits(long[], int).

countBitsUpTo

int countBitsUpTo(int bitIndex)

Forwards to BitUtil.countBitsUpTo(long[], int, int).

nextBitSet

int nextBitSet(int bitIndex)

Forwards to BitUtil.nextBitSet(long[], int, int).

previousBitSet

int previousBitSet(int bitIndex)

Forwards to BitUtil.previousBitSet(long[], int, int).
