F23534-02
The BinaryDeltaCompressor type exposes the following members.
Fields| Name | Description | |
|---|---|---|
  | 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.
