Method Detail

bit

protected static long bit(int pos)

Creates a chunk containing a single bit.

chunkPos

protected static int chunkPos(int size)

Returns which chunk a given bit falls into. Bits 0 to 63 fall in chunk 0, bits 64 to 127 fall into chunk 1.

chunkCount

protected static int chunkCount(int size)

Returns the number of chunks required for a given number of bits.

0 bits requires 0 chunks; 1 - 64 bits requires 1 chunk; etc.

set

public final void set(int pos,
                      boolean value)

Description copied from interface: BitKey

Sets the bit at the specified index to the specified value.

Specified by:

set in interface BitKey

copyFromByte

protected static void copyFromByte(BitSet bitSet,
                                   int pos,
                                   byte x)

copyFromLong

protected static void copyFromLong(BitSet bitSet,
                                   int pos,
                                   long x)
