Class: Zlib::Inflate
- Defined in:
- ext/rubysl/zlib/zlib.c,
ext/rubysl/zlib/zlib.c
Overview
Zlib:Inflate is the class for decompressing compressed data. Unlike Zlib::Deflate, an instance of this class is not able to duplicate (clone, dup) itself.

#<<(string) ⇒ Object
Inputs
string
into the inflate stream just like Zlib::Inflate#inflate, but returns the Zlib::Inflate object itself. -
#inflate(string) ⇒ Object
Inputs
string
into the inflate stream and returns the output from the stream. -
#Zlib::Inflate.new(window_bits) ⇒ Object
constructor
Creates a new inflate stream for decompression.
-
#set_dictionary ⇒ Object
Sets the preset dictionary and returns
string
. -
#sync(string) ⇒ Object
Inputs
string
into the end of input buffer and skips data until a full flush point can be found. -
#sync_point? ⇒ Boolean

Constructor Details
#Zlib::Inflate.new(window_bits) ⇒ Object
Creates a new inflate stream for decompression. See zlib.h for details of the argument. If window_bits
is nil
, the default value is used.

Instance Method Details
#<<(string) ⇒ Object
Inputs string
into the inflate stream just like Zlib::Inflate#inflate, but returns the Zlib::Inflate object itself. The output from the stream is preserved in output buffer.

#inflate(string) ⇒ Object
Inputs string
into the inflate stream and returns the output from the stream. Calling this method, both the input and the output buffer of the stream are flushed. If string is nil
, this method finishes the stream, just like Zlib::ZStream#finish.
Raises a Zlib::NeedDict exception if a preset dictionary is needed to decompress. Set the dictionary by Zlib::Inflate#set_dictionary and then call this method again with an empty string. (???)

#set_dictionary ⇒ Object
Sets the preset dictionary and returns string
. This method is available just only after a Zlib::NeedDict exception was raised. See zlib.h for details.

#sync(string) ⇒ Object
Inputs string
into the end of input buffer and skips data until a full flush point can be found. If the point is found in the buffer, this method flushes the buffer and returns false. Otherwise it returns true
and the following data of full flush point is preserved in the buffer.
