ACE_Event_Handler * | eh_ |
The event handler being managed. | |
bool | refcounted_ |
true if eh_ is a reference-counted handler. |
This class makes the reference count manipulation that occurs during an upcall exception-safe. Prior to dispatching the event handler, the reference count is increased. Once the upcall for the given event handler is complete, its reference count will be decreased.
|
Constructor. The constructor checks to see if eh is a reference-counted handler and remember that for later. If eh is reference counted, its reference count is incremented unless do_incr is false. do_incr should be false if the reference count was incremented independently of this guard, for example, on a notify handler since the reference count is incremented when the notify is queued. |
|
Destructor. The destructor decrements the reference count on the event handler corresponding to the given handle. |
|
Release the event handler from this guard; when the destructor is called, the handler's reference count will not be decremented. |
