Method Details

snappy

public static SnappyOptions snappy()

Create a new SnappyOptions

gzip

public static GzipOptions gzip()

Default implementation of GzipOptions with compressionLevel() set to 6, windowBits() set to 15 and memLevel() set to 8.

gzip

public static GzipOptions gzip(int compressionLevel,
 int windowBits,
 int memLevel)

Create a new GzipOptions Instance

Parameters:

compressionLevel - 1 yields the fastest compression and 9 yields the best compression. 0 means no compression. The default compression level is 6.

windowBits - The base two logarithm of the size of the history buffer. The value should be in the range 9 to 15 inclusive. Larger values result in better compression at the expense of memory usage. The default value is 15.

memLevel - How much memory should be allocated for the internal compression state. 1 uses minimum memory and 9 uses maximum memory. Larger values result in better and faster compression at the expense of memory usage. The default value is 8

deflate

public static DeflateOptions deflate()

Default implementation of DeflateOptions with compressionLevel set to 6, windowBits set to 15 and memLevel set to 8.

deflate

public static DeflateOptions deflate(int compressionLevel,
 int windowBits,
 int memLevel)

Create a new DeflateOptions Instance

Parameters:

compressionLevel - 1 yields the fastest compression and 9 yields the best compression. 0 means no compression. The default compression level is 6.

windowBits - The base two logarithm of the size of the history buffer. The value should be in the range 9 to 15 inclusive. Larger values result in better compression at the expense of memory usage. The default value is 15.

memLevel - How much memory should be allocated for the internal compression state. 1 uses minimum memory and 9 uses maximum memory. Larger values result in better and faster compression at the expense of memory usage. The default value is 8
