+# class http\Encoding\Stream\Deflate extends http\Encoding\Stream
+
+A deflate stream supporting deflate, zlib and gzip encodings.
+
+## Constants:
+
+* TYPE_GZIP
+ Gzip encoding. RFC1952
+* TYPE_ZLIB
+ Zlib encoding. RFC1950
+* TYPE_RAW
+ Deflate encoding. RFC1951
+* LEVEL_DEF
+ Default compression level.
+* LEVEL_MIN
+ Least compression level.
+* LEVEL_MAX
+ Greatest compression level.
+* STRATEGY_DEF
+ Default compression strategy.
+* STRATEGY_FILT
+ Filtered compression strategy.
+* STRATEGY_HUFF
+ Huffman strategy only.
+* STRATEGY_RLE
+ Run-length encoding strategy.
+* STRATEGY_FIXED
+ Encoding with fixed Huffman codes only.
+
+> **A note on the compression strategy:**
+>
+> The strategy parameter is used to tune the compression algorithm.
+>
+> Use the value DEFAULT_STRATEGY for normal data, FILTERED for data produced by a filter (or predictor), HUFFMAN_ONLY to force Huffman encoding only (no string match), or RLE to limit match distances to one (run-length encoding).
+>
+> Filtered data consists mostly of small values with a somewhat random distribution. In this case, the compression algorithm is tuned to compress them better. The effect of FILTERED is to force more Huffman coding and less string matching; it is somewhat intermediate between DEFAULT_STRATEGY and HUFFMAN_ONLY.
+>
+> RLE is designed to be almost as fast as HUFFMAN_ONLY, but give better compression for PNG image data.
+>
+> FIXED prevents the use of dynamic Huffman codes, allowing for a simpler decoder for special applications.
+>
+> The strategy parameter only affects the compression ratio but not the correctness of the compressed output even if it is not set appropriately.
