Detailed Description

A Handler for timer. It helps in the management of timers registered with the Proactor.

This object has a thread that will wait on the earliest time in a list of timers and an event. When a timer expires, the thread will post a completion event on the port and go back to waiting on the timer queue and event. If the event is signaled, the thread will refresh the time it is currently waiting on (in case the earliest time has changed).

Constructor & Destructor Documentation

ACE_Proactor_Timer_Handler::ACE_Proactor_Timer_Handler ( ACE_Proactor & proactor )

Constructor.

ACE_Proactor_Timer_Handler::~ACE_Proactor_Timer_Handler ( void ) [virtual]

Destructor.

Member Function Documentation

int ACE_Proactor_Timer_Handler::destroy ( void )

Proactor calls this to shut down the timer handler gracefully. Just calling the destructor alone doesnt do what <destroy> does. <destroy> make sure the thread exits properly.

int ACE_Proactor_Timer_Handler::signal ( void )

Proactor calls this to refresh the timer event thread, to wake up the thread from a sleep. This is needed to make the thread recompute its sleep time after changes to the timer queue.

int ACE_Proactor_Timer_Handler::svc ( void ) [protected, virtual]

Run by a daemon thread to handle deferred processing. In other words, this method will do the waiting on the earliest timer and event.

Reimplemented from ACE_Task_Base.
