## Detailed Description

An abstract class for implementing the Reactor Pattern.

## 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]`

| Reimplemented in ACE_Msg_WFMO_Reactor, ACE_Select_Reactor_T, 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]`

| Reimplemented in ACE_Msg_WFMO_Reactor, ACE_Select_Reactor_T, 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. Reimplemented in ACE_FlReactor, ACE_QtReactor, ACE_Select_Reactor_T, 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 * | 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, ACE_XtReactor, and ACE_Select_Reactor_T< ACE_Select_Reactor_Token >.

virtual 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, ACE_WFMO_Reactor, and ACE_Select_Reactor_T< ACE_Select_Reactor_Token >.

virtual 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, 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. Reimplemented in ACE_Select_Reactor_T, 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. Reimplemented in ACE_Select_Reactor_T, 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. Reimplemented in ACE_Select_Reactor_T, 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. Reimplemented in ACE_Select_Reactor_T, ACE_WFMO_Reactor, and ACE_Select_Reactor_T< ACE_Select_Reactor_Token >.

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

| Dump the state of an object. Reimplemented in ACE_Priority_Reactor, ACE_Select_Reactor_T, 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. Reimplemented in ACE_Msg_WFMO_Reactor, ACE_Select_Reactor_T, 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. Reimplemented in ACE_Msg_WFMO_Reactor, ACE_Select_Reactor_T, 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 ** | 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. Reimplemented in ACE_Select_Reactor_T, 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 ** | handler = 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, ACE_WFMO_Reactor, and ACE_Select_Reactor_T< ACE_Select_Reactor_Token >.

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

| Returns true if Reactor has been successfully initialized, else false. Reimplemented in ACE_Select_Reactor_T, ACE_WFMO_Reactor, and ACE_Select_Reactor_T< ACE_Select_Reactor_Token >.

virtual ACE_Lock& ACE_Reactor_Impl::lock | ( | void |  | ) | `[pure virtual]`

| Returns a reference to the Reactor's internal lock. Reimplemented in ACE_Select_Reactor_T, ACE_WFMO_Reactor, and ACE_Select_Reactor_T< ACE_Select_Reactor_Token >.

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

| GET/SET/ADD/CLR the dispatch MASK "bit" bound with the <handle> and <mask>. Reimplemented in ACE_Select_Reactor_T, ACE_TP_Reactor, ACE_WFMO_Reactor, and ACE_Select_Reactor_T< ACE_Select_Reactor_Token >.

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

virtual int ACE_Reactor_Impl::max_notify_iterations | ( | void |  | ) | `[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. Reimplemented in ACE_Select_Reactor_T, ACE_WFMO_Reactor, and ACE_Select_Reactor_T< ACE_Select_Reactor_Token >.

virtual int ACE_Reactor_Impl::notify | ( | ACE_Event_Handler * | eh = 0,

  arg | argument passed to the handle_timeout() method of event_handler
  delta | time interval after which the timer will expire
  interval | time interval after which the timer will be automatically rescheduled
Returns: -1 on failure, a timer_id value on success Reimplemented in ACE_FlReactor, ACE_QtReactor, ACE_Select_Reactor_T, ACE_TkReactor, ACE_WFMO_Reactor, ACE_XtReactor, and ACE_Select_Reactor_T< ACE_Select_Reactor_Token >.
