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.
|
inlinestatic |
Increase the counter reference count and return argument.
|
inlinestatic |
Create a ACE_Bound_Ptr_Counter<ACE_LOCK> and initialize the reference count to indicate ownership by a strong pointer.
|
inlinestatic |
Create a ACE_Bound_Ptr_Counter<ACE_LOCK> and initialize the reference count to indicate no ownership.
|
inlinestatic |
Decreases both the object and counter reference counts and deletes whichever has no more references. Returns the new object reference count.
|
inlinestatic |
Decreases the counter reference count and deletes the counter if it has no more references.
|
inlinestaticprivate |
Allocate a new ACE_Bound_Ptr_Counter<ACE_LOCK> instance, returning NULL if it cannot be created.
|
inlinestatic |
Determine whether the object has been deleted.
ACE_Bound_Ptr_Counter< ACE_LOCK >::ACE_ALLOC_HOOK_DECLARE |
Declare the dynamic allocation hooks.

Mutex variable to synchronize access to the reference counts.
|
private |
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 Is set to -1 once the object has been destroyed to indicate to all weak pointers that it is no longer valid.

Reference count of this counter.
