25 // G4MulticoutDestination
26 //
27 // Class description:
28 //
29 // Extends G4coutDestination and allows multiple G4coutDestination objects
30 // to be chained in the same job.
31 // Note that formatters can be attached to this destination that will apply
32 // them before passing over the message to the child destination.
33 //
34 // Usage:
35 // User should create and set-up G4coutDestination objects the usual way
36 // these should then be added to an instance of this container class
37 // this class should then be added to the streaming. E.g.
38 // class MyCout1 : public G4coutDestination {};
39 // class MyCout2 : public G4coutDestination {};
40 // auto multi = new G4MulticoutDestination();
41 // multi->push_back( G4coutDestinationUPtr( new MyCout1 ) );
42 // multi->push_back( G4coutDestinationUPtr( new MyCout2 ) );
43 // G4iosSetDestination( multi ); // or G4cerrbuf
