Detailed Description

template<typename T>
class dd4hep::dd4hep_file_sink< T >

dd4hep file sink extension to boost::iostreams

Basic data sink implementation. Please see boost::iostreams for details. This got inspired by boost::iostreams::device::file_descriptor

The final aim is to hide all this behind a TFile object, so that we get the entire network file handling for free!

Note: Credits go to a large extend to the authors of boost::iostreams. Without their work I could not have done this!

Author: M.Frank

Version: 1.0
