Rose::BinaryAnalysis::Strings::BasicLengthEncodingScheme Class Reference

Description

Basic length encoding scheme.

This length encoding scheme converts a length to a sequence of octets in big- or little-endian order, and vice versa. It needs to know the number of octets per length value, and the byte order of the octets if the length is greater than one.

Member Function Documentation

virtual Ptr Rose::BinaryAnalysis::Strings::BasicLengthEncodingScheme::clone ( ) const

inlineoverridevirtual

Create a new copy of this encoder.

Implements Rose::BinaryAnalysis::Strings::LengthEncodingScheme.

Definition at line 465 of file String.h.

virtual std::string Rose::BinaryAnalysis::Strings::BasicLengthEncodingScheme::name ( ) const

overridevirtual

Name of encoder.

Implements Rose::BinaryAnalysis::Strings::LengthEncodingScheme.

virtual Octets Rose::BinaryAnalysis::Strings::BasicLengthEncodingScheme::encode ( size_t  )

overridevirtual

Encode a length into a sequence of octets.

Implements Rose::BinaryAnalysis::Strings::LengthEncodingScheme.

virtual State Rose::BinaryAnalysis::Strings::BasicLengthEncodingScheme::decode ( Octet  )

overridevirtual

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.

Implements Rose::BinaryAnalysis::Strings::LengthEncodingScheme.

virtual size_t Rose::BinaryAnalysis::Strings::BasicLengthEncodingScheme::consume ( )

overridevirtual

Consume a decoded length.

The decoder must be in the FINAL_STATE or COMPLETE_STATE, and upon return will be in the INITIAL_STATE.

Implements Rose::BinaryAnalysis::Strings::LengthEncodingScheme.

virtual void Rose::BinaryAnalysis::Strings::BasicLengthEncodingScheme::reset ( )

overridevirtual

Reset the decoder state machine.

Implements Rose::BinaryAnalysis::Strings::LengthEncodingScheme.
