pack-priv final Class JPEGHuffmanTable

extends JPEGVariableSizeSegment
Class Inheritance
JPEGHuffmanTable class actually represents two types of object: 1) A DHT (Define Huffman Tables) segment, which may represent as many as 4 Huffman tables. In this case, the tables are stored in the allTables array. 2) A single Huffman table. In this case, the allTables array will be null. The 'reference' field is stored in both types of object, but 'initialize' is only called if the object represents a DHT.
