Creates a Huffman table and initializes it. The input arrays are copied. The arrays must describe a possible Huffman table. For example, 3 codes cannot be expressed with a single bit.
lengths | an array of shorts where lengths[k]
is equal to the number of values with corresponding codes of
length k + 1 bits. | |
values | an array of shorts containing the values in order of increasing code length. |
IllegalArgumentException | if lengths or
values are null, the length of lengths is
greater than 16, the length of values is greater than 256,
if any value in lengths or values is less
than zero, or if the arrays do not describe a valid Huffman table. |
