Method BitList

Return the list of bits which are set in b encoded as followed:

(i >>> (4 * n)) & 0x0F

is the offset of the n-th set bit of

the given byte plus one, or 0 if there are n or less bits set in the given byte. For example

bitList(12)

returns 0x43:

• 0x43 & 0x0F

  is 3, meaning the the first bit set is at offset 3-1 = 2,

• (0x43 >>> 4) & 0x0F

  is 4, meaning there is a second bit set at offset 4-1=3,

• (0x43 >>> 8) & 0x0F

  is 0, meaning there is no more bit set in this byte.
