An object oriented event demultiplexor and event handler dispatcher.
The ACE_Select_Reactor is an object-oriented event demultiplexor and event handler dispatcher. The sources of events that the ACE_Select_Reactor waits for and dispatches includes I/O events, signals, and timer events. All public methods acquire the main ACE_Reactor_Token lock and call down to private or protected methods, which assume that the lock is held and so therefore don't (re)acquire the lock.
| ACE_Select_Reactor_T< ACE_SELECT_REACTOR_TOKEN >::ACE_Select_Reactor_T | ( | ACE_Sig_Handler * | sh = 0, |
| ACE_Timer_Queue * | tq = 0, |
||
| int | disable_notify_pipe = ACE_DISABLE_NOTIFY_PIPE_DEFAULT, |
||
| ACE_Reactor_Notify * | notify = 0, |
||
| bool | mask_signals = true, |
||
| int | s_queue = ACE_SELECT_TOKEN::FIFO |
||
| ) |
If disable_notify_pipe is non-0 then the reactor will not create a notification pipe, which will save two I/O handles but will elide the notify() feature. If mask_signals is true the reactor is "signal-safe" when dispatching handlers to signal events, whereas if mask_signals is false the reactor will be more efficient, but not signal-safe (which may be perfectly fine if your application doesn't use the reactor to handle signals).

This event loop driver that blocks for max_wait_time before returning. It will return earlier if timer events, I/O events, or signal 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 I/O and Timer ACE_Event_Handler's that were dispatched, 0 if the max_wait_time elapsed without dispatching any handlers, or -1 if something goes wrong.
Current alertable_handle_events() is identical to handle_events().
Implements ACE_Reactor_Impl.

Cancel all <event_handlers> that match the address of event_handler. If dont_call_handle_close is 0 then the <handle_close> method of event_handler will be invoked. Returns number of handler's cancelled.
Implements ACE_Reactor_Impl.
|
virtual |
Cancel the single ACE_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. If dont_call_handle_close is 0 then the <handle_close> method of <event_handler> will be invoked. Returns 1 if cancellation succeeded and 0 if the timer_id wasn't found.

Set the maximum number of times that the <ACE_Select_Reactor_Notify::handle_input> method will iterate and dispatch the ACE_Event_Handlers that are passed in via the notify pipe before breaking out of its <recv> loop. By default, this is set to -1, which means "iterate until the pipe 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.

Schedule an ACE_Event_Handler that will expire after an amount of time. The return value of this method, a timer_id value, uniquely identifies the event_handler in the ACE_Reactor's internal list of timers. This timer_id value can be used to cancel the timer with the cancel_timer() call.
| 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 |

Return true if we any event associations were made by the reactor for the handles that it waits on, false otherwise. Since the Select_Reactor does not do any event associations, this function always return false.
