com.bigdata.io.compression.TestHuffmanEncoder.HuffmanEncoder

Enclosing class:

TestHuffmanEncoder

public static class TestHuffmanEncoder.HuffmanEncoder
extends Object

Class provides only the huffman encoding aspect of the ZLIB compression standard. Note that this class, which wraps Deflater, uses adaptive huffman encoding and (a) does NOT allow you to isolate the dictionary from the input; and (b) does NOT allow you to use a static code based on frequency counts or the entire input.

Instances of this class are NOT thread-safe.
