Stream class Stream: Undocumented in source.

Functions

end void end(Stream stream): Undocumented in source. Be warned that the author may not have intended to support it.

process Flag!"streamEnded" process(Stream stream, Flag!"lastChunk" lastChunk): Undocumented in source. Be warned that the author may not have intended to support it.
reset void reset(Stream stream): Undocumented in source. Be warned that the author may not have intended to support it.

Variables

chainLog int chainLog;: Common paramters. A value of zero indicates that the default should be used.
checksumFlag bool checksumFlag;: Include a checksum of the content in the trailer.
compressionLevel int compressionLevel;: Common paramters. A value of zero indicates that the default should be used.
contentSize ulong contentSize;: If input data content size is known, before start of streaming, set contentSize to its value. It will enable the size to be written in the header and checked after decompression.
dictIdFlag bool dictIdFlag;: When applicable, dictionary's ID is written in the header
enableLongDistanceMatching bool enableLongDistanceMatching;: Long distance matching parameters (LDM) Can be activated for large inputs to improve the compression ratio. Increases memory usage and the window size A value of zero indicate that the default should be used.
hashLog int hashLog;: Common paramters. A value of zero indicates that the default should be used.
jobSize int jobSize;: Multi-threading parameters
ldmBucketSizeLog int ldmBucketSizeLog;
ldmHashLog int ldmHashLog;
ldmHashRateLog int ldmHashRateLog;
ldmMinMatch int ldmMinMatch;: Long distance matching parameters (LDM) Can be activated for large inputs to improve the compression ratio. Increases memory usage and the window size A value of zero indicate that the default should be used.
minMatch int minMatch;: Common paramters. A value of zero indicates that the default should be used.
nbWorkers int nbWorkers;
overlapLog int overlapLog;: Multi-threading parameters
searchLog int searchLog;
strategy int strategy;
targetLength int targetLength;
windowLog int windowLog;: Common paramters. A value of zero indicates that the default should be used.
