Class Encoder

  uk.org.retep.util.io.lzma.Encoder

public class Encoder
extends java.lang.Object

Part of the LZMA SDK 4.63 written and placed in the public domain by Igor Pavlov.

The LZMA SDK provides the documentation, samples, header files, libraries, and tools you need to develop applications that use LZMA compression.

LZMA is default and general compression method of 7z format in 7-Zip compression program (www.7-zip.org). LZMA provides high compression ratio and very fast decompression.

LZMA is an improved version of famous LZ77 compression algorithm. It was improved in way of maximum increasing of compression ratio, keeping high decompression speed and low memory requirements for decompressing.

This version is virtually identical to his version except minor refactoring to conform with coding standards and Java 6.

Since:

9.1.17
