The ZLibCodec encodes raw bytes to ZLib compressed bytes and decodes ZLib compressed bytes to raw bytes.

Properties
- decoder → ZLibDecoder
-
Get a
ZLibDecoder
for decodingZLib
compressed data.read-only - dictionary → List<int>
-
Initial compression dictionary.…
read-only - encoder → ZLibEncoder
-
Get a
ZLibEncoder
for encoding toZLib
compressed data.read-only - gzip → bool
-
When true,
GZip
frames will be added to the compressed data.read-only - hashCode → int
-
Get a hash code for this object.…
read-only, inherited - inverted → Codec<List<int>, List<int>>
-
Inverts
this
.…read-only, inherited - level → int
-
The compression-level can be set in the range of
-1..9
, with6
being the default compression level. Levels above6
will have higher compression rates at the cost of more CPU and memory usage. Levels below6
will use less CPU and memory at the cost of lower compression rates.read-only - memLevel → int
-
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 value is8
.…read-only - raw → bool
-
When true, deflate generates raw data with no zlib header or trailer, and will not compute an adler32 check value
read-only - runtimeType → Type
-
A representation of the runtime type of the object.
read-only, inherited - strategy → int
-
Tunes the compression algorithm. Use the value STRATEGY_DEFAULT for normal data, STRATEGY_FILTERED for data produced by a filter (or predictor), STRATEGY_HUFFMAN_ONLY to force Huffman encoding only (no string match), or STRATEGY_RLE to limit match distances to one (run-length encoding).
read-only - windowBits → int
-
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 15
