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(); }
typedef UT_IntrusivePtr<Foo> FooHandle;
