public final class BitSequence extends GeneratedMessageV3 implements BitSequenceOrBuilder
A sequence of bits, encoded in a byte array.
Each byte in the bitmap
byte array stores 8 bits of the sequence. The only
exception is the last byte, which may store 8 or fewer bits. The padding
defines the number of bits of the last byte to be ignored as "padding". The
values of these "padding" bits are unspecified and must be ignored.
To retrieve the first bit, bit 0, calculate: (bitmap[0] & 0x01) != 0
.
To retrieve the second bit, bit 1, calculate: (bitmap[0] & 0x02) != 0
.
To retrieve the third bit, bit 2, calculate: (bitmap[0] & 0x04) != 0
.
To retrieve the fourth bit, bit 3, calculate: (bitmap[0] & 0x08) != 0
.
To retrieve bit n, calculate: (bitmap[n / 8] & (0x01 << (n % 8))) != 0
.
The "size" of a BitSequence
(the number of bits it contains) is calculated
by this formula: (bitmap.length * 8) - padding
.
