Detailed Description

template<class T>
class UT_IntrusivePtr< T >

Wrapper around hboost::intrusive_ptr.

An intrusive pointer assumes that the referenced object implements reference counting on itself. The reference counting is implemented using the methods intrusive_ptr_add_ref() and intrusive_ptr_release().

For simple usages, simply derive from UT_IntrusiveRefCounter.

Here's a roll your own example:

class Foo
{
public:
    Foo() : myCount(0) {}
   ~Foo() {}
    void        incref()
                {
                    myCount.add(1);
                }
    void        decref()
                {
                    if (myCount.add(-1) == 0)
                        delete this;
                }
    SYS_AtomicInt32     myCount;
};
static inline void intrusive_ptr_add_ref(Foo *o) { o->incref(); }
static inline void intrusive_ptr_release(Foo *o) { o->decref(); }

using FooHandle = UT_IntrusivePtr<Foo>;
