Constructor & Destructor Documentation

virtual ACE_Reactor_Impl::~ACE_Reactor_Impl (  void    )  [inline, virtual]
 

Close down and release all resources.

Member Function Documentation

virtual int ACE_Reactor_Impl::alertable_handle_events (  ACE_Time_Value &    max_wait_time )  [pure virtual]
 

Implemented in ACE_Dev_Poll_Reactor, ACE_Msg_WFMO_Reactor, ACE_Select_Reactor_T< ACE_SELECT_REACTOR_TOKEN >, ACE_WFMO_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]
 

Implemented in ACE_Dev_Poll_Reactor, ACE_Msg_WFMO_Reactor, ACE_Select_Reactor_T< ACE_SELECT_REACTOR_TOKEN >, ACE_WFMO_Reactor, and ACE_Select_Reactor_T< ACE_Select_Reactor_Token >.

virtual int ACE_Reactor_Impl::cancel_timer (  long    timer_id,
const void **    arg = 0,
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_Dev_Poll_Reactor, ACE_FlReactor, ACE_QtReactor, ACE_Select_Reactor_T< ACE_SELECT_REACTOR_TOKEN >, ACE_TkReactor, ACE_WFMO_Reactor, ACE_XtReactor, and ACE_Select_Reactor_T< ACE_Select_Reactor_Token >.

virtual int ACE_Reactor_Impl::cancel_timer (  ACE_Event_Handler *    event_handler,
int    dont_call_handle_close = 1
)  [pure virtual]
 

Cancel all Event_Handlers that match the address of <event_handler>. Returns number of handlers cancelled.

Implemented in ACE_Dev_Poll_Reactor, ACE_FlReactor, ACE_QtReactor, ACE_Select_Reactor_T< ACE_SELECT_REACTOR_TOKEN >, ACE_TkReactor, ACE_WFMO_Reactor, ACE_XtReactor, and ACE_Select_Reactor_T< ACE_Select_Reactor_Token >.

ACE_Reactor_Mask    masks_to_be_cleared
)  [pure virtual]
 

Clear <masks_to_be_cleared> from the <handle>'s entry.

Implemented in ACE_Dev_Poll_Reactor, ACE_Select_Reactor_T< ACE_SELECT_REACTOR_TOKEN >, ACE_WFMO_Reactor, and ACE_Select_Reactor_T< ACE_Select_Reactor_Token >.

virtual int ACE_Reactor_Impl::cancel_wakeup (  ACE_Event_Handler *    event_handler,
ACE_Reactor_Mask    masks_to_be_cleared
)  [pure virtual]
 

Clear <masks_to_be_cleared> from the <event_handler>'s entry.

Implemented in ACE_Dev_Poll_Reactor, ACE_Select_Reactor_T< ACE_SELECT_REACTOR_TOKEN >, ACE_WFMO_Reactor, 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_Dev_Poll_Reactor, ACE_Select_Reactor_T< ACE_SELECT_REACTOR_TOKEN >, ACE_WFMO_Reactor, 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_Dev_Poll_Reactor, ACE_Select_Reactor_T< ACE_SELECT_REACTOR_TOKEN >, ACE_WFMO_Reactor, and ACE_Select_Reactor_T< ACE_Select_Reactor_Token >.

virtual void ACE_Reactor_Impl::deactivate (  int    do_stop )  [pure virtual]
 

Control whether the Reactor will handle any more incoming events or not. If <do_stop> == 1, the Reactor will be disabled. By default, a reactor is in active state and can be deactivated/reactived as wish.

Implemented in ACE_Dev_Poll_Reactor, ACE_Select_Reactor_T< ACE_SELECT_REACTOR_TOKEN >, ACE_WFMO_Reactor, and ACE_Select_Reactor_T< ACE_Select_Reactor_Token >.

virtual int ACE_Reactor_Impl::deactivated (  void    )  [pure virtual]
 

Return the status of Reactor. If this function returns 0, the reactor is actively handling events. If it returns non-zero, <handling_events> and <handle_alertable_events> return -1 immediately.

Implemented in ACE_Dev_Poll_Reactor, ACE_Select_Reactor_T< ACE_SELECT_REACTOR_TOKEN >, ACE_WFMO_Reactor, and ACE_Select_Reactor_T< ACE_Select_Reactor_Token >.

virtual void ACE_Reactor_Impl::dump (  void    )  const [pure virtual]

Implemented in ACE_Dev_Poll_Reactor, ACE_Priority_Reactor, ACE_Select_Reactor_T< ACE_SELECT_REACTOR_TOKEN >, ACE_WFMO_Reactor, and ACE_Select_Reactor_T< ACE_Select_Reactor_Token >.

virtual ACE_Event_Handler* ACE_Reactor_Impl::find_handler (  ACE_HANDLE    handle )  [pure virtual]
 

Return the Event_Handler associated with <handle>. Return 0 if <handle> is not registered.

Implemented in ACE_Dev_Poll_Reactor, ACE_Select_Reactor_T< ACE_SELECT_REACTOR_TOKEN >, ACE_WFMO_Reactor, and ACE_Select_Reactor_T< ACE_Select_Reactor_Token >.

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_Dev_Poll_Reactor, ACE_Msg_WFMO_Reactor, ACE_Select_Reactor_T< ACE_SELECT_REACTOR_TOKEN >, ACE_TP_Reactor, ACE_WFMO_Reactor, 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_Handler>s 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_Dev_Poll_Reactor, ACE_Msg_WFMO_Reactor, ACE_Select_Reactor_T< ACE_SELECT_REACTOR_TOKEN >, ACE_TP_Reactor, ACE_WFMO_Reactor, and ACE_Select_Reactor_T< ACE_Select_Reactor_Token >.

virtual int ACE_Reactor_Impl::handler (  int    signum,
ACE_Event_Handler **    = 0
)  [pure virtual]
 

Check to see if <signum> is associated with a valid Event_Handler bound to a signal. Return the <event_handler> associated with this <handler> if <event_handler> != 0.

Implemented in ACE_Dev_Poll_Reactor, ACE_Select_Reactor_T< ACE_SELECT_REACTOR_TOKEN >, ACE_WFMO_Reactor, and ACE_Select_Reactor_T< ACE_Select_Reactor_Token >.

virtual int ACE_Reactor_Impl::handler (  ACE_HANDLE    handle,
ACE_Reactor_Mask    mask,
ACE_Event_Handler **    event_handler = 0
)  [pure virtual]

Implemented in ACE_Dev_Poll_Reactor, ACE_Select_Reactor_T< ACE_SELECT_REACTOR_TOKEN >, ACE_WFMO_Reactor, and ACE_Select_Reactor_T< ACE_Select_Reactor_Token >.

virtual void ACE_Reactor_Impl::max_notify_iterations (  int    )  [pure virtual]
 

Set the maximum number of times that ACE_Reactor_Impl will iterate and dispatch the <ACE_Event_Handlers> that are passed in via the notify queue before breaking out of its <ACE_Message_Queue::dequeue> loop. 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_Dev_Poll_Reactor, ACE_Select_Reactor_T< ACE_SELECT_REACTOR_TOKEN >, ACE_WFMO_Reactor, and ACE_Select_Reactor_T< ACE_Select_Reactor_Token >.

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
