add_weak_pointer
Description:
public void add_weak_pointer (void** weak_pointer_location)
Adds a weak reference from weak_pointer to this to indicate that the pointer located at
weak_pointer_location is only valid during the lifetime of this.
When the this is finalized, weak_pointer will be set to null.
Note that as with weak_ref, the weak references created by this method are not thread-safe: they cannot safely be used in one thread if the object's last unref might happen in another thread. Use WeakRef if thread-safety is required.
Parameters:
| this |
The object that should be weak referenced. |
| weak_pointer_location |
The memory address of a pointer. |
