Interface Codec

All Known Subinterfaces:

PrefixCodec

All Known Implementing Classes:

HuffmanCodec, HuTuckerCodec

public interface Codec

An abstract factory corresponding to an instance of a specific compression technique.

An implementation of this interface provides coders and decoders. The constructors must provide all data that is required to perform coding and decoding.

Method Summary

Coder	coder() Returns a coder for the compression technique represented by this coded.
Decoder	decoder() Returns a decoder for the compression technique represented by this coded.
int	size() Returns the number of symbols handled by this codec.
