class Flate::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.

Class Method Detail

def self.gzip(input, sync_close : Bool = false) : self #

Creates an instance of Flate::Reader for the gzip format. has written.


[View source]
def self.gzip(input, sync_close : Bool = false, &block) #

Creates an instance of Flate::Reader for the gzip format, yields it to the given block, and closes it at its end.


[View source]
def self.new(io : IO, sync_close : Bool = false, dict : Bytes? = nil) #

Creates an instance of Flate::Reader.


[View source]
def self.new(input : IO, sync_close : Bool = false, dict : Bytes? = nil, &block) #

Instance Method Detail

def close #

Closes this reader.


[View source]
def closed? : Bool #

Returns true if this reader is closed.


[View source]
def read(slice : Bytes) #

See IO#read.


[View source]
def sync_close=(sync_close : Bool) #

If #sync_close? is true, closing this IO will close the underlying IO.


[View source]
def sync_close? : Bool #

If #sync_close? is true, closing this IO will close the underlying IO.


[View source]
def write(slice : Bytes) #

Always raises IO::Error because this is a read-only IO.
