Class JPEGHuffmanTable
The JPEGHuffmanTable class represents a Huffman table read from a
JPEG image file. The standard JPEG AC and DC chrominance and
luminance values are provided as static fields.
JPEGHuffmanTable(short[] lengths, short[] values)- Construct and initialize a Huffman table.

JPEGHuffmanTable
public JPEGHuffmanTable(short[] lengths,
short[] values) Construct and initialize a Huffman table. Copies are created of
the array arguments. lengths[index] stores the number of Huffman
values with Huffman codes of length index + 1. The values array
stores the Huffman values in order of increasing code length.
lengths - an array of Huffman code lengthsvalues - a sorted array of Huffman values
IllegalArgumentException - if either parameter is null, if
lengths.length > 16 or values.length > 256, if any value in
length or values is negative, or if the parameters do not
describe a valid Huffman table
getLengths
public short[] getLengths()
Retrieve a copy of the array of Huffman code lengths. If the
returned array is called lengthcount, there are
lengthcount[index] codes of length index + 1.
- a copy of the array of Huffman code lengths
getValues
public short[] getValues()
Retrieve a copy of the array of Huffman values, sorted in order
of increasing code length.
- a copy of the array of Huffman values
toString
public String toString()
Create a string representation of this JPEG Huffman table.
- toString in interface Object
- a string representation of this JPEG Huffman table.
