Field Summary

Fields

Modifier and Type	Field and Description
static int	DeflateRecommended The most optimised compression, with a good balance of speed and compression efficiency.
static int	ZipLevel0 The data will be simply stored, with no change at all.
static int	ZipLevel1 The fastest but least effective compression.
static int	ZipLevel2 A little slower, but better, than level 1.
static int	ZipLevel3 A little slower, but better, than level 2.
static int	ZipLevel4 A little slower, but better, than level 3.
static int	ZipLevel5 A little slower than level 4, but with better compression.
static int	ZipLevel6 A little slower than level 5, but with better compression.
static int	ZipLevel7 Better compression than level 6, but even slower.
static int	ZipLevel8 Better compression than level 7, but even slower.
static int	ZipLevel9 The "best" compression, where best means greatest reduction in size of the input data stream.
