Static Public Methods | |
| ACE_Bound_Ptr_Counter<ACE_LOCK>* | create_strong (void) |
| Create a ACE_Bound_Ptr_Counter and initialize the reference count to indicate ownership by a strong pointer. | |
| int | attach_strong (ACE_Bound_Ptr_Counter<ACE_LOCK> *counter) |
| Increase both the object and counter reference counts and return the new object reference count. A return value of -1 indicates that the object has already been destroyed. | |
| int | detach_strong (ACE_Bound_Ptr_Counter<ACE_LOCK> *counter) |
| Decreases both the object and counter reference counts and deletes whichever has no more references. Returns the new object reference count. | |
| ACE_Bound_Ptr_Counter<ACE_LOCK>* | create_weak (void) |
| Create a ACE_Bound_Ptr_Counter and initialize the reference count to indicate no ownership. | |
| void | attach_weak (ACE_Bound_Ptr_Counter<ACE_LOCK> *counter) |
| Increase the counter reference count and return argument. | |
| void | detach_weak (ACE_Bound_Ptr_Counter<ACE_LOCK> *counter) |
| Decreases the counter reference count and deletes the counter if it has no more references. | |
| int | object_was_deleted (ACE_Bound_Ptr_Counter<ACE_LOCK> *counter) |
| Determine whether the object has been deleted. | |
Private Attributes | |
| int | obj_ref_count_ |
| Reference count of underlying object. Is set to -1 once the object has been destroyed to indicate to all weak pointers that it is no longer valid. | |
| int | self_ref_count_ |
| Reference count of this counter. | |
| ACE_LOCK | lock_ |
| Mutex variable to synchronize access to the reference counts. | |
