Description
Encoding for the length of a string.
Strings that are length-encoded must specify a length encoding scheme that gives the length of the string measured in code points.

Member Function Documentation
|
pure virtual |
Create a new copy of this encoder.
Implemented in Rose::BinaryAnalysis::Strings::BasicLengthEncodingScheme.
|
pure virtual |
Name of encoder.
Implemented in Rose::BinaryAnalysis::Strings::BasicLengthEncodingScheme.
|
pure virtual |
Encode a length into a sequence of octets.
Implemented in Rose::BinaryAnalysis::Strings::BasicLengthEncodingScheme.
|
inline |
Decode one octet.
Processes a single octet and updates the decoder state machine. Returns the decoder's new state. See documentation for State for restrictions on state transitions.
Implemented in Rose::BinaryAnalysis::Strings::BasicLengthEncodingScheme.
|
pure virtual |
Consume a decoded length.
The decoder must be in the FINAL_STATE or COMPLETE_STATE, and upon return will be in the INITIAL_STATE.
Implemented in Rose::BinaryAnalysis::Strings::BasicLengthEncodingScheme.
|
pure virtual |
Reset the decoder state machine.
Implemented in Rose::BinaryAnalysis::Strings::BasicLengthEncodingScheme.
