Reference documentation and code samples for the Cloud Bigtable V2 Client class OrderedCodeBytes.
Fields are encoded independently and concatenated with the fixed byte
pair {0x00, 0x01}
in between.
Any null (0x00)
byte in an encoded field is replaced by the fixed
byte pair {0x00, 0xFF}
.
Fields that encode to the empty string "" have special handling:
- If every field encodes to "", or if the STRUCT has no fields
defined, then the STRUCT is encoded as the fixed byte pair
{0x00, 0x00}
. - Otherwise, the STRUCT only encodes until the last non-empty field,
omitting any trailing empty fields. Any empty fields that aren't
omitted are replaced with the fixed byte pair
{0x00, 0x00}
. Examples: ```php - STRUCT() -> "\00\00"
- STRUCT("") -> "\00\00"
- STRUCT("", "") -> "\00\00"
- STRUCT("", "B") -> "\00\00" + "\00\01" + "B"
- STRUCT("A", "") -> "A"
- STRUCT("", "B", "") -> "\00\00" + "\00\01" + "B"
- STRUCT("A", "", "C") -> "A" + "\00\01" + "\00\00" + "\00\01" + "C"
`` Since null bytes are always escaped, this encoding can cause size blowup for encodings like
Int64.BigEndianBytes` that are likely to produce many such bytes. Sorted mode: - Fields are encoded in sorted mode.
- All values supported by the field encodings are allowed
- Element-wise order is preserved:
A < B
ifA[0] < B[0]
, or ifA[0] == B[0] && A[1] < B[1]
, etc. Strict prefixes sort first. Distinct mode: - Fields are encoded in distinct mode.
- All values supported by the field encodings are allowed.
