ref_intrusive_policy Struct Reference

#include <smart_ptr.hpp>

List of all members.

---

Detailed Description

Use this policy to create an intrusive reference smart pointer. In general, this policy is faster than both ref_count_policy and ref_link_policy. However, it requires three intrusive functions that take the target type pointer as a parameter.
void intrusive_ptr_add_ref(T *);
void intrusive_ptr_release(T *);
bool intrusive_ptr_is_ref(T *);
Example implementation for intrusive functions:
void intrusive_ptr_add_ref(Shape * p){++(p->references);}
void intrusive_ptr_release(Shape * p){
if (--(p->references) == 0)
delete p;
}
bool intrusive_ptr_is_ref(Shape * p){return (p->references > 1);}

Example Usage.

void example_ref_intrusive_policy_usage()
{
}

Note:

The ref_link_policy can still be used in synchronized code, if intrusive_lock_policy is used.
