19// Class: AliDimeRndm
20// Responsibilities: Interface to Root random number generator
21// from Fortran (re-implements FINCTION RLU_HIJING
22// from HIJING)
23// Note: Since AliGenDime belongs to another module (TDime) one cannot
24// pass the ponter to the generator via static variable
25// Collaborators: AliGenDime class
26// Example:
27//
28// root> AliGenDime *gener = new AliGenDime(-1);
29// root> AliDimeRndm::SetDimeRandom(new TRandom3());
30// root> AliDimeRndm::GetDimeRandom()->SetSeed(0);
31// root> cout<<"Seed "<< AliDimeRndm::GetDimeRandom()->GetSeed() <<endl;
