U:RDoc::NormalClass[iI"ZStream:ETI"Zlib::ZStream;TI"Object;To:RDoc::Markup::Document:@parts[o;;[o:RDoc::Markup::Paragraph;[I"JZlib::ZStream is the abstract class for the stream which handles the ;TI"Dcompressed data.

I"PAn instance of Zlib::ZStream has one stream (struct zstream in the source) ;TI"Pand two variable-length buffers which associated to the input (next_in) of ;TI"Kthe stream and the output (next_out) of the stream. In this document, ;TI"N"input buffer" means the buffer for input, and "output buffer" means the ;TI"buffer for output.;T@o;	;[I"MData input into an instance of Zlib::ZStream are temporally stored into ;TI"Othe end of input buffer, and then data in input buffer are processed from ;TI"Ithe beginning of the buffer until no more output from the stream is ;TI"Oproduced (i.e. until avail_out > 0 after processing).  During processing, ;TI"Noutput buffer is allocated and expanded automatically to hold all output ;TI"
data.;T@o;	;[I"LSome particular instance methods consume the data in output buffer and ;TI"return them as a String.;T@o;	;[I"/Here is an ascii art for describing above:;T@o:RDoc::Markup::Verbatim;[I"F+================ an instance of Zlib::ZStream ================+
