Method: Zlib.inflate

Defined in:
zlib.c

.inflate(src) ⇒ Object

call-seq:

Zlib.inflate(string)
Zlib::Inflate.inflate(string)

Decompresses string. Raises a Zlib::NeedDict exception if a preset dictionary is needed for decompression.

This method is almost equivalent to the following code:

def inflate(string)
  zstream = Zlib::Inflate.new
  buf = zstream.inflate(string)
  zstream.finish
  zstream.close
  buf
end
