Detailed Description

template<class Body, class Counter = RWAtomicCounter>
class RWTCountingPointer< Body, Counter >

Defines a reference-counted pointer that provides reference counting semantics for types that do not directly support reference counting. Body, the first template parameter, can be any type. For the second template parameter, Counter, you will generally use RWAtomicCounter.

A user-defined counter class must provide the following interface:

class Counter
{
public:
    // Constructs a counter instance with an initial count of x.
    Counter(int x);
    // Increments the reference count by one.
    void addReference();
    // Decrements the reference count by one.
    // Must return 0 after the last reference count is removed,
    // indicating that it is safe to deallocate the body instance.
    int removeReference();
};

Example: #include <rw/pointer/RWTCountingPointer.h>

int main()

{

RWTCountingPointer<int> pointer = new int(10);

return 0;

}
