StreamFormat Property
The stream format to use.
Syntax
public var streamFormat: ZipstreamStreamFormats {
get {...}
set {...} }
public enum ZipstreamStreamFormats: Int32 { case sfDeflate = 0 case sfZlib = 1 case sfGzip = 2 }
Default Value
0
Remarks
The stream format to use, by default Deflate.
All three stream formats use the Deflate algorithm specified in RFC 1951, which is the same algorithm used by Zip. The Zlib stream format adds a two-byte header and an Adler-32 checksum; the Gzip format adds a longer header and a CRC checksum, and is identical to the Gzip file format.
Caution: The terms zlib and deflate are sometimes used interchangeably (which is technically incorrect).
