TRandom3 random generator status

I am little naive in ROOT. I want to create Poissonian numbers using TRndom3 object. However i need that even if this object goes out of scope or PC is restarted, every time new call to member method PoissonD(mean) is made, it should give me random number which is in accordance to last status of random number generator. How can this be done??

You could store the TRandom3 object in the ROOT file … see also … [url]Question about gRandom and TUUID
