Re: [reSIProcate] Reference Counting Smart Pointer
Will the smart pointer be used in multiple-thread
environment? If yes, you may need to add mutex to
serialize its access. But the overhead of serializing
operation may over-counter the performance brought
from shared pointer.
In VOVIDA, it used a lot of smarter pointer. But in
resiprocate, the smarter pointer was totally removed.
Any anyone explain the reason?
