Constructor & Destructor Documentation

dirac::ArithCodecBase::ArithCodecBase ByteIO p_byteio,
size_t  number_of_contexts
 

Creates an ArithCodec object to decode input based on a set of parameters.

Parameters:
p_byteio input/output for encoded bits
number_of_contexts the number of contexts used

virtual dirac::ArithCodecBase::~ArithCodecBase  )  [virtual]
 

Destructor is virtual as this class is abstract.
