Interface PrefixCodec

  • All Superinterfaces:
    Codec
    All Known Implementing Classes:
    HuffmanCodec, HuTuckerCodec
    public interface PrefixCodec
extends Codec
    A codec based on a set of prefix-free codewords.

    Prefix codec work by building a vector of prefix-free codewords, one for each symbol. The method codeWords() returns that vector. Moreover, this interface strengthens the return type of coder() to PrefixCoder.

    • Method Summary
