| int | restart = 0, |
|||
| ACE_Sig_Handler * | = 0, |
|||
| ACE_Timer_Queue * | = 0, |

| ) | [pure virtual] |
Initialization.
Implemented in ACE_Select_Reactor_T< ACE_SELECT_REACTOR_TOKEN >, and ACE_Select_Reactor_T< ACE_Select_Reactor_Token >.
| virtual int ACE_Reactor_Impl::current_info | ( | ACE_HANDLE | , | |
| size_t & | ||||
| ) | [pure virtual] |
Returns 0, if the size of the current message has been put in size Returns -1, if not. ACE_HANDLE allows the reactor to check if the caller is valid.
Implemented in ACE_Select_Reactor_T< ACE_SELECT_REACTOR_TOKEN >, and ACE_Select_Reactor_T< ACE_Select_Reactor_Token >.
| virtual int ACE_Reactor_Impl::set_sig_handler | ( | ACE_Sig_Handler * | signal_handler | ) | [pure virtual] |
Use a user specified signal handler instead.
Implemented in ACE_Select_Reactor_T< ACE_SELECT_REACTOR_TOKEN >, and ACE_Select_Reactor_T< ACE_Select_Reactor_Token >.
| virtual int ACE_Reactor_Impl::timer_queue | ( | ACE_Timer_Queue * | tq | ) | [pure virtual] |
Set a user-specified timer queue.
Implemented in ACE_Select_Reactor_T< ACE_SELECT_REACTOR_TOKEN >, and ACE_Select_Reactor_T< ACE_Select_Reactor_Token >.
| virtual ACE_Timer_Queue* ACE_Reactor_Impl::timer_queue | ( | void | ) | const [pure virtual] |
Return the current ACE_Timer_Queue.
Implemented in ACE_Select_Reactor_T< ACE_SELECT_REACTOR_TOKEN >, and ACE_Select_Reactor_T< ACE_Select_Reactor_Token >.
| virtual int ACE_Reactor_Impl::close | ( | void | ) | [pure virtual] |
Close down and release all resources.
Implemented in ACE_Select_Reactor_T< ACE_SELECT_REACTOR_TOKEN >, and ACE_Select_Reactor_T< ACE_Select_Reactor_Token >.
| virtual int ACE_Reactor_Impl::work_pending | ( | const ACE_Time_Value & | max_wait_time = ACE_Time_Value::zero |
) | [pure virtual] |
Returns non-zero if there are I/O events "ready" for dispatching, but does not actually dispatch the event handlers. By default, don't block while checking this, i.e., "poll".
Implemented in ACE_Select_Reactor_T< ACE_SELECT_REACTOR_TOKEN >, and ACE_Select_Reactor_T< ACE_Select_Reactor_Token >.
| virtual int ACE_Reactor_Impl::handle_events | ( | ACE_Time_Value * | max_wait_time = 0 |
) | [pure virtual] |
This event loop driver blocks for up to max_wait_time before returning. It will return earlier if events occur. Note that max_wait_time can be 0, in which case this method blocks indefinitely until events occur.
max_wait_time is decremented to reflect how much time this call took. For instance, if a time value of 3 seconds is passed to handle_events and an event occurs after 2 seconds, max_wait_time will equal 1 second. This can be used if an application wishes to handle events for some fixed amount of time.
Returns the total number of ACE_Event_Handlers that were dispatched, 0 if the max_wait_time elapsed without dispatching any handlers, or -1 if an error occurs.
The only difference between <alertable_handle_events> and <handle_events> is that in the alertable case, the eventloop will return when the system queues an I/O completion routine or an Asynchronous Procedure Call.
Implemented in ACE_Select_Reactor_T< ACE_SELECT_REACTOR_TOKEN >, ACE_TP_Reactor, and ACE_Select_Reactor_T< ACE_Select_Reactor_Token >.
| virtual int ACE_Reactor_Impl::alertable_handle_events | ( | ACE_Time_Value * | max_wait_time = 0 |
) | [pure virtual] |
| virtual int ACE_Reactor_Impl::handle_events | ( | ACE_Time_Value & | max_wait_time | ) | [pure virtual] |
This method is just like the one above, except the max_wait_time value is a reference and can therefore never be NULL.
The only difference between <alertable_handle_events> and <handle_events> is that in the alertable case, the eventloop will return when the system queues an I/O completion routine or an Asynchronous Procedure Call.
Implemented in ACE_Select_Reactor_T< ACE_SELECT_REACTOR_TOKEN >, ACE_TP_Reactor, and ACE_Select_Reactor_T< ACE_Select_Reactor_Token >.
| virtual int ACE_Reactor_Impl::alertable_handle_events | ( | ACE_Time_Value & | max_wait_time | ) | [pure virtual] |
| virtual int ACE_Reactor_Impl::deactivated | ( | void | ) | [pure virtual] |

Implemented in ACE_Select_Reactor_T< ACE_SELECT_REACTOR_TOKEN >, and ACE_Select_Reactor_T< ACE_Select_Reactor_Token >.
| virtual void ACE_Reactor_Impl::deactivate | ( | int | do_stop | ) | [pure virtual] |

- See also:
- cancel_timer()
- Parameters:
-
event_handler event handler to schedule on reactor arg argument passed to the handle_timeout() method of event_handler delay time interval after which the timer will expire interval time interval after which the timer will be automatically rescheduled
- Returns:

|||
| int | dont_call_handle_close = 1 | |||
| ) | [pure virtual] |
Cancel the single Event_Handler that matches the timer_id value (which was returned from the schedule method). If arg is non-NULL then it will be set to point to the ``magic cookie'' argument passed in when the Event_Handler was registered. This makes it possible to free up the memory and avoid memory leaks. Returns 1 if cancellation succeeded and 0 if the timer_id wasn't found.
Implemented in ACE_Select_Reactor_T< ACE_SELECT_REACTOR_TOKEN >, and ACE_Select_Reactor_T< ACE_Select_Reactor_Token >.

|
| ACE_Reactor_Mask | mask = ACE_Event_Handler::EXCEPT_MASK, |
|||
| ACE_Time_Value * | = 0 | |||
| ) | [pure virtual] |
Notify event_handler of mask event. The ACE_Time_Value indicates how long to blocking trying to notify. If timeout == 0, the caller will block until action is possible, else will wait until the relative time specified in timeout elapses).

By default, this is set to -1, which means "iterate until the queue is empty." Setting this to a value like "1 or 2" will increase "fairness" (and thus prevent starvation) at the expense of slightly higher dispatching overhead.
Implemented in ACE_Select_Reactor_T< ACE_SELECT_REACTOR_TOKEN >, and ACE_Select_Reactor_T< ACE_Select_Reactor_Token >.
