not exactly:-( suppose I'd like to read a binary file's content into
the memory once (to save file i/o operation in order to make it faster)
than a factory create object which can initialize itself from the 
binary stream. so I'd like to give the factory a stream which has 
the content of the binary file. currently iy's not solvable with
stringstream (but strstream), since istringstream.rdbuf()->pubsetbuf(..)
do nothing:-( so what is the solution?
