Returns a bit mask for the specified number of bits.

if (numberOfBits >= 32) {
 return -1;
return (numberOfBits == 0 ? 0 : powerOf(2, numberOfBits) - 1);

int bitMask(int bit)
Calculate a bitmask of the bit.

assert bit >= 0 && bit < 16;
return 1 << bit;

return (0xFFFFFFFF >>> (SZ_INT - bitSize));
