|

<p>Currently, SWCompression creates only one block for all data
|
||
and the block can either be uncompressed or compressed with static Huffman encoding.
|
||
Choice of one block type or the other depends on bytes’ statistics of data.
|
||
However, if data size is greater than 65535 (the maximum value stored in 2 bytes),
|
||
then static Huffman block will be created.</p>
