typedef 使用

比如， typedef G4THitsCollection<B2TrackerHit> B2TrackerHitsCollection;  将  G4THitsCollection<B2TrackerHit> 重命名为  B2TrackerHitsCollection

 文件流作为函数参数

1 void fitshape(std::ofstream &ffo, TString fitfunc, Int_t start, Int_t stop);
2 
3 std::ofstream ffo;
4 ffo.open("test.tt", std::fstream::app); 
5 TString sss("test"); 6 fd_tmp->fitshape(ffo, sss, 0, 4000);
