The provided std::istream may either be std::cin, sone (gziped) file or an aleady existig std::istream.
An optional name arument may be passed to the ctor, to identify the stream in log messages, even if it is not a file.
Per default the name is "STDIN", the path to an input file or empty.
void parse( const InputStream & input = InputStream() ) { // process input.stream() and refer to input.name() // in log messages. } parse(); // std::cin parse( "/some/file" ); // file parse( "/some/file.gz" ); // gziped file std::istream & mystream; parse( mystream ); // some existing stream parse( InputStream( mystream, "my stream's name" ) );

| const std::string& zypp::InputStream::name | ( | ) | const [inline] |
Name of the std::istream.
Per default this is "STDIN", the path to an input file or empty. A custom string may be provided to the ctor.
This may be used in log messages to identify the stream even even if it is not a file.

Set the size of the input stream.
You may set it to whatever vaule is appropriate. E.g. *=10 to compensate gzip comression. or the number of items, lines, ... The value is not used here, just provided.
