Dear all,
Sorry I forgot one important issue in my example code in the last mail:
If we set random generator to RandomGen, the destructor of RandomGen should not delete the copied pointer.
We need owner flag inside RandomGen.
I also have another minor request : inside destructor in some classes, there are cout calls and we can't make them silence.
Would it be under control of logging system, or make silence mode as default?
I don't know where should I send these requests, if this ML is not appropriate please let me know.
Thank you,
Kotoyo
