## Constructor & Destructor Documentation

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]`

| Reimplemented in ACE_Msg_WFMO_Reactor, ACE_Select_Reactor_T, and ACE_WFMO_Reactor.

virtual int ACE_Reactor_Impl::alertable_handle_events ( | ACE_Time_Value * max_wait_time = 0 )`[pure virtual]`

| Reimplemented in ACE_Msg_WFMO_Reactor, ACE_Select_Reactor_T, and ACE_WFMO_Reactor.

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. Reimplemented in ACE_FlReactor, ACE_QtReactor, ACE_Select_Reactor_T, ACE_TkReactor, ACE_WFMO_Reactor, and ACE_XtReactor.

int ACE_Reactor_Impl::cancel_timer ( | ACE_Event_Handler * 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. Reimplemented in ACE_FlReactor, ACE_QtReactor, ACE_Select_Reactor_T, ACE_TkReactor, ACE_WFMO_Reactor, and ACE_XtReactor.

int ACE_Reactor_Impl::cancel_wakeup ( | ACE_HANDLE handle,
| ACE_Reactor_Mask mask )`[pure virtual]`

| Clear <masks_to_be_cleared> from the <handle>'s entry. Reimplemented in ACE_Select_Reactor_T, and ACE_WFMO_Reactor.

int ACE_Reactor_Impl::cancel_wakeup ( | ACE_Event_Handler * eh,
| ACE_Reactor_Mask mask )`[pure virtual]`

| Clear <masks_to_be_cleared> from the <event_handler>'s entry. Reimplemented in ACE_Select_Reactor_T, and ACE_WFMO_Reactor.

int ACE_Reactor_Impl::close ( | void )`[pure virtual]`

| Close down and release all resources. Reimplemented in ACE_Select_Reactor_T, and ACE_WFMO_Reactor.

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. Reimplemented in ACE_Select_Reactor_T, and ACE_WFMO_Reactor.

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. Reimplemented in ACE_Select_Reactor_T, and ACE_WFMO_Reactor.

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. Reimplemented in ACE_Select_Reactor_T, and ACE_WFMO_Reactor.

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

| Dump the state of an object. Reimplemented in ACE_Priority_Reactor, ACE_Select_Reactor_T, and ACE_WFMO_Reactor.

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 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. Reimplemented in ACE_Msg_WFMO_Reactor, ACE_Select_Reactor_T, ACE_TP_Reactor, and ACE_WFMO_Reactor.

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 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 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. Reimplemented in ACE_Msg_WFMO_Reactor, ACE_Select_Reactor_T, ACE_TP_Reactor, and ACE_WFMO_Reactor.

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

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

| Check to see if <handle> is associated with a valid Event_Handler bound to <mask>. Return the <event_handler> associated with this <handler> if <event_handler> != 0. Reimplemented in ACE_Select_Reactor_T, and ACE_WFMO_Reactor.

int ACE_Reactor_Impl::initialized ( | void )`[pure virtual]`

void ACE_Reactor_Impl::max_notify_iterations ( | int iterations )`[pure virtual]`

| Set the maximum number of times that ACE_Reactor_Impl will iterate and dispatch the that are passed in via the notify queue before breaking out of its 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. Reimplemented in ACE_Select_Reactor_T, and ACE_WFMO_Reactor.

int ACE_Reactor_Impl::notify ( | ACE_Event_Handler * eh = 0,
| ACE_Reactor_Mask mask = ACE_Event_Handler::EXCEPT_MASK,

virtual ACE_Timer_Queue* ACE_Reactor_Impl::timer_queue ( | void ) const`[pure virtual]`

| Reimplemented in ACE_Select_Reactor_T, and ACE_WFMO_Reactor.

int ACE_Reactor_Impl::timer_queue ( | ACE_Timer_Queue * tq )`[pure virtual]`

| Set a user-specified timer queue. Return the current . Reimplemented in ACE_Select_Reactor_T, and ACE_WFMO_Reactor.

int ACE_Reactor_Impl::uses_event_associations ( | void )`[pure virtual]`

| Return 1 if we any event associations were made by the reactor for the handles that it waits on, 0 otherwise. Reimplemented in ACE_Select_Reactor_T, and ACE_WFMO_Reactor.

void ACE_Reactor_Impl::wakeup_all_threads ( | void )`[pure virtual]`

| Wake up all threads in waiting in the event loop. Reimplemented in ACE_Select_Reactor_T, and ACE_WFMO_Reactor.

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". Reimplemented in ACE_Select_Reactor_T, and ACE_WFMO_Reactor.
