Constructors

ZLibCodec ( {int level: ZLibOption.DEFAULT_LEVEL, int windowBits: ZLibOption.DEFAULT_WINDOW_BITS, int memLevel: ZLibOption.DEFAULT_MEM_LEVEL, int strategy: ZLibOption.STRATEGY_DEFAULT, List<int> dictionary: null, bool raw: false, bool gzip: false} )

Instance Properties

gzip bool
read-only
When true, GZip frames will be added to the compressed data.
level int
read-only
The compression-level can be set in the range of -1..9, with 6 being the default compression level. Levels above 6 will have higher compression rates at the cost of more CPU and memory usage. Levels...
memLevel int
read-only
Specifies how much memory should be allocated for the internal compression state. 1 uses minimum memory but is slow and reduces compression ratio; 9 uses maximum memory for optimal speed. The default ...
strategy int
read-only
Tunes the compression algorithm. Use the value STRATEGYDEFAULT for normal data, STRATEGYFILTERED for data produced by a filter (or predictor), STRATEGYHUFFMANONLY to force Huffman encoding only (no st...
windowBits int
read-only
Base two logarithm of the window size (the size of the history buffer). It should be in the range 8..15. Larger values result in better compression at the expense of memory usage. The default value is...
raw bool
read-only
When true, deflate generates raw data with no zlib header or trailer, and will not compute an adler32 check value
dictionary List<int>
read-only
Initial compression dictionary.
encoder Converter<List<int>,List<int>>
read-only
decoder Converter<List<int>,List<int>>
read-only
inverted Codec<List<int>,List<int>> Inherited
read-only
inverted Codec<List<int>,List<int>> Inherited
read-only
