Using generic std::function objects with member functions in one class
...:placeholders::_1, std::placeholders::_2);
Or, if your compiler supports C++11 lambdas:
std::function<void(int,int)> f = [=](int a, int b) {
this->doSomethingArgs(a, b);
}
(I don't have a C++11 capable compiler at hand right now, so I can't check this one.)

}
C++ and others have a couple ways to solve this, eg

Should I pass a shared_ptr by reference? [duplicate]
...ce, to avoid the overhead of copying the shared_ptr.
The best practice in C++ is always to have clearly defined ownership semantics for your objects. There is no universal "always do this" to replace actual thought.
If you always pass shared pointers by value, it gets costly (because they're a lot...
Copying a HashMap in Java

The difference is that in C++ your object is on the stack, whereas in Java, your object is in the heap. If A and B are Objects, any time in Java you do:
B = A
A and B point to the same object, so anything you do to A you do to B and vice versa.
