Detailed Description

Class used to make event handler reference count manipulation exception-safe.

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 & Destructor Documentation

ACE_Dev_Poll_Handler_Guard::ACE_Dev_Poll_Handler_Guard ( ACE_Event_Handler eh,
bool  do_incr = true 


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.

ACE_Dev_Poll_Handler_Guard::~ACE_Dev_Poll_Handler_Guard ( void  )


The destructor decrements the reference count on the event handler corresponding to the given handle.

Member Function Documentation

void ACE_Dev_Poll_Handler_Guard::release ( void  )

Release the event handler from this guard; when the destructor is called, the handler's reference count will not be decremented.
