The BinaryDeltaCompressor type exposes the following members.

Fields

  NameDescription
DELTA_TRUNCATE
A delta value that indicates an empty new value.
FMT_BINDIFF
A format indicator (the first byte of the binary delta) that indicates that the new value is formed by applying a series of modifications to the old value. The possible modifications are defined by the OP_* constants.
FMT_EMPTY
A format indicator (the first byte of the binary delta) that indicates that the new value is a zero-length binary value.
FMT_REPLACE
A format indicator (the first byte of the binary delta) that indicates that the new value is found in its entirety in the delta value. In other words, other than the first byte, the delta is itself the new value.
MIN_BLOCK
Minimum length of an "extract" block to encode.
NO_BINARY
An empty Binary object.
OP_APPEND
A binary delta operator that instructs the {@link #applyDelta} method to copy the following bytes from the delta value and append them to the new value. The format is the one-byte OP_APPEND indicator followed by a packed int length and then a series of bytes. The length indicates the length of the series of bytes to copy from the delta value and append to the new value.
OP_EXTRACT
A binary delta operator that instructs the ApplyDelta(Binary, Binary) method to extract bytes from the old value and append them to the new value. The format is the one-byte OP_EXTRACT indicator followed by a packed int offset and packed int length. The offset and length indicate the region of the old value to extract and append to the new value.
OP_TERM
A binary delta operator that instructs the {@link #applyDelta} method that the delta has been fully applied.
