33 // Class description:
34 //
35 // Extends G4coutDestination and allows multiple G4coutDestination objects
36 // to be chained in the same job.
37 // Note that formatters can be attached to this destination that will apply
38 // them before passing over the message to the child destination.
39 //
40 // Usage:
41 // User should create and set-up G4coutDestination objects the usual way
42 // these should then be added to an instance of this container class
43 // this class should then be added to the streaming. E.g.
44 // class MyCout1 : public G4coutDestination {};
45 // class MyCout2 : public G4coutDestination {};
46 // auto multi = new G4MulticoutDestination();
47 // multi->push_back( G4coutDestinationUPtr( new MyCout1 ) );
48 // multi->push_back( G4coutDestinationUPtr( new MyCout2 ) );
49 // G4coutbuf.SetDestination( multi ); // or G4cerrbuf
