virtual int handle_events (ACE_Time_Value *max_wait_time = 0) = 0;
virtual int alertable_handle_events (

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.
virtual int handle_events (ACE_Time_Value &max_wait_time) = 0;
virtual int alertable_handle_events (
ACE_Time_Value &max_wait_time
) = 0;
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.
virtual int deactivated (void) = 0;
handling_events and
handle_alertable_events return -1 immediately.
virtual void deactivate (int do_stop) = 0;
do_stop == 1, the Reactor will be disabled. By default, a reactor
is in active state and can be deactivated/reactived as wish.
virtual int register_handler (
ACE_Event_Handler *event_handler,
ACE_Reactor_Mask mask
) = 0;
event_handler with mask. The I/O handle will always
come from get_handle on the event_handler.
virtual int register_handler (
ACE_HANDLE io_handle,
ACE_Event_Handler *event_handler,
ACE_Reactor_Mask mask
) = 0;
event_handler with mask. The I/O handle is provided
through the io_handle parameter.
Originally this interface was available for all platforms, but because ACE_HANDLE is an int on non-Win32 platforms, compilers are not able to tell the difference between register_handler(ACE_Event_Handler*,ACE_Reactor_Mask) and register_handler(ACE_Event_Handler*,ACE_HANDLE). Therefore, we have restricted this method to Win32 only.
virtual int register_handler (
ACE_Event_Handler *event_handler,
ACE_HANDLE event_handle = ACE_INVALID_HANDLE
) = 0;
event_handler that will be notified when
event_handle is signaled. Since no event mask is passed
through this interface, it is assumed that the event_handle
being passed in is an event handle and not an I/O handle.
virtual int register_handler (
ACE_HANDLE event_handle,
ACE_HANDLE io_handle,
ACE_Event_Handler *event_handler,
ACE_Reactor_Mask mask
) = 0;
event_handler that will be notified when
event_handle is signaled. mask specifies the network events
that the event_handler is interested in.
virtual int register_handler (
const ACE_Handle_Set &handles,
ACE_Event_Handler *event_handler,
ACE_Reactor_Mask mask
) = 0;
event_handler with all the handles in the Handle_Set.
virtual int register_handler (
int signum,
ACE_Event_Handler *new_sh,
ACE_Sig_Action *new_disp = 0,
ACE_Event_Handler **old_sh = 0,
ACE_Sig_Action *old_disp = 0
) = 0;
new_sh to handle the signal signum using the
new_disp. Returns the old_sh that was previously registered
(if any), along with the old_disp of the signal handler.
virtual int register_handler (
const ACE_Sig_Set &sigset,
ACE_Event_Handler *new_sh,
ACE_Sig_Action *new_disp = 0
) = 0;
new_sh to handle a set of signals sigset using the
new_disp.
virtual int remove_handler (
ACE_Event_Handler *event_handler,
ACE_Reactor_Mask mask
) = 0;
event_handler. Note that the I/O handle will be
obtained using get_handle method of event_handler . If
mask == ACE_Event_Handler::DONT_CALL then the handle_close
method of the event_handler is not invoked.
virtual int remove_handler (
ACE_HANDLE handle,
ACE_Reactor_Mask mask
) = 0;
handle. If mask == ACE_Event_Handler::DONT_CALL
then the handle_close method of the associated event_handler
is not invoked.
virtual int remove_handler (
const ACE_Handle_Set &handle_set,
ACE_Reactor_Mask mask
) = 0;
handle_set. If mask ==
ACE_Event_Handler::DONT_CALL then the handle_close method of
the associated event_handlers is not invoked.
virtual int remove_handler (
int signum,
ACE_Sig_Action *new_disp,
ACE_Sig_Action *old_disp = 0,
int sigkey = -1
) = 0;
signum.
Install the new disposition (if given) and return the previous
disposition (if desired by the caller). Returns 0 on success and
-1 if signum is invalid.
virtual int remove_handler (const ACE_Sig_Set &sigset) = 0;
remove_handler for every signal in sigset.
virtual int suspend_handler (ACE_Event_Handler *event_handler) = 0;
event_handler temporarily. Use
ACE_Event_Handler::get_handle to get the handle.
virtual int suspend_handler (ACE_HANDLE handle) = 0;
handle temporarily.
virtual int suspend_handler (const ACE_Handle_Set &handles) = 0;
handles in handle set temporarily.
virtual int suspend_handlers (void) = 0;
handles temporarily.
virtual int resume_handler (ACE_Event_Handler *event_handler) = 0;
event_handler. Use ACE_Event_Handler::get_handle to
get the handle.
virtual int resume_handler (ACE_HANDLE handle) = 0;
handle.
virtual int resume_handler (const ACE_Handle_Set &handles) = 0;
handles in handle set.
virtual int resume_handlers (void) = 0;
handles.
virtual int uses_event_associations (void) = 0;
If we need to reset handles returned from accept/connect.
virtual long schedule_timer (
ACE_Event_Handler *event_handler,
const void *arg,
const ACE_Time_Value &delta,
const ACE_Time_Value &interval = ACE_Time_Value::zero
) = 0;
event_handler that will expire after delay amount
of time, which is specified as relative time to the current
gettimeofday. If it expires then arg is passed in as the
value to the event_handler's handle_timeout callback method.
If interval is != to ACE_Time_Value::zero then it is used to
reschedule the event_handler automatically, also using relative
time. This method returns a timer_id that uniquely identifies
the event_handler in an internal list. This timer_id can be
used to cancel an event_handler before it expires. The
cancellation ensures that timer_ids are unique up to values of
greater than 2 billion timers. As long as timers don't stay
around longer than this there should be no problems with
accidentally deleting the wrong timer. Returns -1 on failure
(which is guaranteed never to be a valid timer_id.
virtual int reset_timer_interval (
long timer_id,
const ACE_Time_Value &interval
) = 0;
timer_id to
interval, which is specified in relative time to the current
gettimeofday. If interval is equal to
ACE_Time_Value::zero, the timer will become a non-rescheduling
timer. Returns 0 if successful, -1 if not.
virtual int cancel_timer (
ACE_Event_Handler *event_handler,
int dont_call_handle_close = 1
) = 0;
event_handler. Returns number of handlers cancelled.
virtual int cancel_timer (
long timer_id,
const void **arg = 0,
int dont_call_handle_close = 1
) = 0;
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.
virtual int schedule_wakeup (
ACE_Event_Handler *event_handler,
ACE_Reactor_Mask masks_to_be_added
) = 0;
masks_to_be_added to the event_handler's entry.
event_handler must already have been registered.
virtual int schedule_wakeup (
ACE_HANDLE handle,
ACE_Reactor_Mask masks_to_be_added
) = 0;
masks_to_be_added to the handle's entry. event_handler
associated with handle must already have been registered.
virtual int cancel_wakeup (
ACE_Event_Handler *event_handler,
ACE_Reactor_Mask masks_to_be_cleared
) = 0;
masks_to_be_cleared from the event_handler's entry.
virtual int cancel_wakeup (
ACE_HANDLE handle,
ACE_Reactor_Mask masks_to_be_cleared
) = 0;
masks_to_be_cleared from the handle's entry.
virtual int notify (
ACE_Event_Handler *event_handler = 0,
ACE_Reactor_Mask mask = ACE_Event_Handler::EXCEPT_MASK,
ACE_Time_Value * = 0
) = 0;
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).
virtual void max_notify_iterations (int) = 0;
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.
virtual int max_notify_iterations (void) = 0;
ACE_Event_Handlers that are passed in
via the notify queue before breaking out of its
ACE_Message_Queue::dequeue loop.
virtual int handler (
ACE_HANDLE handle,
ACE_Reactor_Mask mask,
ACE_Event_Handler **event_handler = 0
) = 0;
handle is associated with a valid Event_Handler
bound to mask. Return the event_handler associated with this
handler if event_handler != 0.
virtual int handler (int signum, ACE_Event_Handler ** = 0) = 0;
