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

virtual Ptr Rose::BinaryAnalysis::Strings::LengthEncodingScheme::clone ( ) const
pure virtual

Create a new copy of this encoder.

Implemented in Rose::BinaryAnalysis::Strings::BasicLengthEncodingScheme.

virtual std::string Rose::BinaryAnalysis::Strings::LengthEncodingScheme::name ( ) const
pure virtual
virtual Octets Rose::BinaryAnalysis::Strings::LengthEncodingScheme::encode ( size_t  )
pure virtual

Encode a length into a sequence of octets.

Implemented in Rose::BinaryAnalysis::Strings::BasicLengthEncodingScheme.

State Rose::BinaryAnalysis::Strings::LengthEncodingScheme::state ( ) const
inline

Decoder state.

Definition at line 425 of file BinaryString.h.

virtual State Rose::BinaryAnalysis::Strings::LengthEncodingScheme::decode ( Octet  )
pure virtual

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.

virtual size_t Rose::BinaryAnalysis::Strings::LengthEncodingScheme::consume ( )
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.

virtual void Rose::BinaryAnalysis::Strings::LengthEncodingScheme::reset ( )
pure virtual

Reset the decoder state machine.

Implemented in Rose::BinaryAnalysis::Strings::BasicLengthEncodingScheme.
