Member Function Documentation

virtual int ACE_Reactor_Notify::close (  void    )  [pure virtual]

Implemented in ACE_Dev_Poll_Reactor_Notify, ACE_Select_Reactor_Notify, and ACE_WFMO_Reactor_Notify.

virtual int ACE_Reactor_Notify::dispatch_notifications (  int &    number_of_active_handles, ACE_Handle_Set &    rd_mask )  [pure virtual]

Handles pending threads (if any) that are waiting to unblock the <Reactor_Impl>. Implemented in ACE_Dev_Poll_Reactor_Notify, ACE_Select_Reactor_Notify, and ACE_WFMO_Reactor_Notify.

virtual int ACE_Reactor_Notify::dispatch_notify (  ACE_Notification_Buffer &    buffer )  [pure virtual]

Handle one of the notify call on the <handle>. This could be because of a thread trying to unblock the <Reactor_Impl> Implemented in ACE_Dev_Poll_Reactor_Notify, ACE_Select_Reactor_Notify, and ACE_WFMO_Reactor_Notify.

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

Dump the state of an object. Implemented in ACE_Dev_Poll_Reactor_Notify, ACE_Select_Reactor_Notify, and ACE_WFMO_Reactor_Notify.

virtual int ACE_Reactor_Notify::is_dispatchable (  ACE_Notification_Buffer &    buffer )  [pure virtual]

Verify whether the buffer has dispatchable info or not. Implemented in ACE_Dev_Poll_Reactor_Notify, ACE_Select_Reactor_Notify, and ACE_WFMO_Reactor_Notify.

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

Get the maximum number of times that the <handle_input> method will iterate and dispatch the <ACE_Event_Handlers> that are passed in via the notify queue before breaking out of its event loop. Implemented in ACE_Dev_Poll_Reactor_Notify, ACE_Select_Reactor_Notify, and ACE_WFMO_Reactor_Notify.

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

Set the maximum number of times that the <handle_input> method will iterate and dispatch the <ACE_Event_Handlers> that are passed in via the notify queue before breaking out of the event 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_Notify, ACE_Select_Reactor_Notify, and ACE_WFMO_Reactor_Notify.

virtual int ACE_Reactor_Notify::notify (  ACE_Event_Handler *    = 0, ACE_Reactor_Mask    = ACE_Event_Handler::EXCEPT_MASK, ACE_Time_Value *    = 0 )  [pure virtual]

Called by a thread when it wants to unblock the <Reactor_Impl>. This wakeups the <Reactor_Impl> if currently blocked. Pass over both the <Event_Handler> *and* the <mask> to allow the caller to dictate which <Event_Handler> method the <Reactor_Impl> will invoke. The <ACE_Time_Value> indicates how long to blocking trying to notify the <Reactor_Impl>. If <timeout> == 0, the caller will block until action is possible, else will wait until the relative time specified in *<timeout> elapses). Implemented in ACE_Dev_Poll_Reactor_Notify, ACE_Select_Reactor_Notify, and ACE_WFMO_Reactor_Notify.

virtual ACE_HANDLE ACE_Reactor_Notify::notify_handle (  void    )  [pure virtual]

Returns the ACE_HANDLE of the notify pipe on which the reactor is listening for notifications so that other threads can unblock the <Reactor_Impl> Implemented in ACE_Dev_Poll_Reactor_Notify, ACE_Select_Reactor_Notify, and ACE_WFMO_Reactor_Notify.

virtual int ACE_Reactor_Notify::open (  ACE_Reactor_Impl *   , ACE_Timer_Queue *    timer_queue = 0, int    disable_notify = 0 )  [pure virtual]

Implemented in ACE_Dev_Poll_Reactor_Notify, ACE_Select_Reactor_Notify, and ACE_WFMO_Reactor_Notify.

virtual int ACE_Reactor_Notify::purge_pending_notifications (  ACE_Event_Handler *    = 0, ACE_Reactor_Mask    = ACE_Event_Handler::ALL_EVENTS_MASK )  [pure virtual]

Purge any notifications pending in this reactor for the specified <ACE_Event_Handler> object. Returns the number of notifications purged. Returns -1 on error. Implemented in ACE_Dev_Poll_Reactor_Notify, ACE_Select_Reactor_Notify, and ACE_WFMO_Reactor_Notify.

virtual int ACE_Reactor_Notify::read_notify_pipe (  ACE_HANDLE    handle, ACE_Notification_Buffer &    buffer )  [pure virtual]

Read one of the notify call on the <handle> into the <buffer>. This could be because of a thread trying to unblock the <Reactor_Impl> Implemented in ACE_Dev_Poll_Reactor_Notify, ACE_Select_Reactor_Notify, and ACE_WFMO_Reactor_Notify.
