Detailed Description

Out file stream that offers on-the-fly gzip-compression.

The class accesses an internal std::ofstream. This can be used to open a file and write compressed data to it.

The class is based on the zstr::ofstream class of the excellent zstr library by Matei David; see also our Acknowledgements.

If genesis is compiled without zlib support, constructing an instance of this class will throw an exception.
