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.
