public sealed class BitSequence : IMessage<BitSequence>, IEquatable<BitSequence>, IDeepCloneable<BitSequence>, IBufferMessage, IMessage
Reference documentation and code samples for the Firestore v1 API class BitSequence.
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.
The number of bits of the last byte in bitmap to ignore as "padding".
If the length of bitmap is zero, then this value must be 0.
Otherwise, this value must be between 0 and 7, inclusive.
