Method Summary

Modifier and Type	Method and Description
public static BrotliOptions	brotli() Default implementation of `BrotliOptions` with `Encoder.Parameters#setQuality(int)` set to 4 and `Encoder.Parameters#setMode(Encoder.Mode)` set to `Encoder.Mode#TEXT`
public static BrotliOptions	brotli(Encoder.Parameters `Encoder.Parameters` Instance parameters) Create a new `BrotliOptions`
public static DeflateOptions	deflate() Default implementation of `DeflateOptions` with `compressionLevel` set to 6, `windowBits` set to 15 and `memLevel` set to 8.
public static DeflateOptions	deflate(int `1` yields the fastest compression and `9` yields the best compression. `0` means no compression. The default compression level is `6`. compressionLevel, int 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`. windowBits, int 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` memLevel) Create a new `DeflateOptions` Instance
