Class GLZ

java.lang.Object
  ch.rgw.compress.GLZ

public class GLZ
extends java.lang.Object

GLZ is a simple implementation of a variation of the lempel-ziv algorithm. It compresses much less than zip, but is fast enough to be implemented in pure Java. (I did program it in assembler originally in the early 90's though; this alorithm programmed in assembler and running on a 80386 of those days was even slower than running on a computer of today in this java programm, which is essentially a transscript of the original Assembler source)
