PrefixCoder (dsiutil 2.6.0)

All Superinterfaces:

Coder

All Known Implementing Classes:

CodeWordCoder, Fast64CodeWordCoder
```
public interface PrefixCoder
extends Coder
```
A coder based on a set of prefix-free codewords.
Not all coders are codeword-based (for instance, arithmetic coding is not codeword-based). However, coders that are based on prefix-free codewords are invited to return by means of Codec.coder() an implementation of this interface.
Note that the coder returned by a PrefixCodec is an implementation of this interface.

```
BitVector[] codeWords()
```
    Provides access to the codewords. Warning: bit 0 of each bit vector returned by codeWords() is the first (leftmost) bit of the corresponding codeword: in other words, codewords are stored in right-to-left fashion.
    
    Returns:
    
    the codewords.
