ref_count_policy Struct Reference

#include <smart_ptr.hpp>

List of all members.

---

Detailed Description

Use this policy to create a reference counting smart pointer. This policy is similar to reference counting logic used by boost::shared_ptr. In general, it is slower than the other two reference policies (ref_link_policy and ref_intrusive_policy). It is more generic than ref_intrusive_policy, since it does not require that the target type have intrusive functions. It takes less space than ref_link_policy, and it's easier to implement in synchronized code, than ref_link_policy. Use this policy when space is the primary factor, or when referencing the same object in multiple threads and you don't wish to use an intrusive_lock_policy.
Example Usage.

#include "../shape_test.h"

void example_ref_count_policy_usage()
{
        smart_ptr<Shape, copy_on_write_policy<ref_count_policy> >       pShape1 = new Square("Blue");

        smart_ptr<Shape, shared_ptr_policy<ref_count_policy> >          pShape2 = new Circle("Red");

        smart_ptr<Shape, copy_on_write_policy<ref_count_policy> >       pShape3 = pShape2; //exchangeable policies

        smart_ptr<Shape, shared_ptr_policy<ref_count_policy> >          pShape4 = pShape1; //exchangeable policies
}
