TIBCO Adapter SDK C++ Reference
MDataEvent::confirm
MDataEvent
Perform explicit confirmation that event is consumed. This is required when MSubscriber::noAutoConfirm() is called for certified listeners.
Remarks
The default behavior of certified listeners is to automatically confirm message delivery upon return from the data callback function. Programs can selectively override this behavior for specific listening endpoints (without affecting other listening endpoints).

By overriding automatic confirmation, the listener assumes responsibility for explicitly confirming each inbound certified message. Consider overriding automatic confirmation when processing inbound messages involves asynchronous activity, such as computations in other threads, database queries, or additional network communications.

This method works regardless of message format (validated or non-validated).

Declaration
virtual void confirm() const throw(MException);
