LZF-compress is a Java library for encoding and decoding data in LZF format,
|
|
|
|
|
written by Tatu Saloranta (tatu.saloranta@iki.fi).
|
|
|
|
|
|
|
|
|
|
Data format and algorithm based on original LZF library by Marc A Lehmann. See
|
|
|
|
|
LZF Format Specification for full description.
|
|
|
|
|
|
|
|
|
|
Format differs slightly from some other adaptations, such as the one used by H2
|
|
|
|
|
database project (by Thomas Mueller); although internal block compression
|
|
|
|
|
structure is the same, block identifiers differ. This package uses the original
|
|
|
|
|
LZF identifiers to be 100% compatible with existing command-line lzf tool(s).
|
|
|
|
|
|
|
|
|
|
LZF algorithm itself is optimized for speed, with somewhat more modest
|
|
|
|
|
compression. Compared to the standard Deflate (algorithm gzip uses) LZF can be
|
|
|
|
|
5-6 times as fast to compress, and twice as fast to decompress. Compression
|
|
|
|
|
rate is lower since no Huffman-encoding is used after lempel-ziv substring
|
|
|
|
|
elimination.
