class Compress::Deflate::Reader
Overview
A read-only IO
object to decompress data in the DEFLATE format.
Instances of this class wrap another IO object. When you read from this instance instance, it reads data from the underlying IO, decompresses it, and returns it to the caller.
Included Modules
Defined in:
compress/deflate/reader.crConstructors
-
.gzip(input, sync_close : Bool = false) : self
Creates an instance of Flate::Reader for the gzip format.
-
.new(io : IO, sync_close : Bool = false, dict : Bytes | Nil = nil)
Creates an instance of Flate::Reader.
Class Method Summary
-
.gzip(input, sync_close : Bool = false, &)
Creates an instance of Flate::Reader for the gzip format, yields it to the given block, and closes it at its end.
-
.open(io : IO, sync_close : Bool = false, dict : Bytes | Nil = nil, &)
Creates a new reader from the given io, yields it to the given block, and closes it at its end.
