Detailed Description

A Reactor implementation that uses the Fast-Light (FL) toolkit for event demultiplexing. This will let us integrate the FL toolkit with ACE and/or TAO.

As many other GUI toolkits FL supports a minimal set of callbacks to handle event demultiplexing, namely simple methods to add file descriptors to the event demuxing set or timeout events. This class adapts this simple mechanisms so they are compatible with ACE's Reactor.

Member Function Documentation

int ACE_FlReactor::cancel_timer (  long    timer_id, const void **    arg = 0, int    dont_call_handle_close = 1 )  [virtual]

Cancel the single <ACE_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. If <dont_call_handle_close> is 0 then the <handle_close> method of <event_handler> will be invoked. Returns 1 if cancellation succeeded and 0 if the <timer_id> wasn't found. Reimplemented from ACE_Select_Reactor_T< ACE_Select_Reactor_Token >.

int ACE_FlReactor::cancel_timer (  ACE_Event_Handler *    handler, int    dont_call_handle_close = 1 )  [virtual]

Cancel all <event_handlers> that match the address of <event_handler>. If <dont_call_handle_close> is 0 then the <handle_close> method of <event_handler> will be invoked. Returns number of handler's cancelled. Reimplemented from ACE_Select_Reactor_T< ACE_Select_Reactor_Token >.

void ACE_FlReactor::fl_io_proc (  int    fd, void *    )  [static, private]

void ACE_FlReactor::fl_timeout_proc (  void *    )  [static, private]

ACE_FlReactor& ACE_FlReactor::operator= (  const ACE_FlReactor &    )  [private]

int ACE_FlReactor::register_handler_i (  const ACE_Handle_Set &    handles, ACE_Event_Handler *    handler, ACE_Reactor_Mask    mask )  [protected, virtual]

Register a set of <handlers>. Reimplemented from ACE_Select_Reactor_T< ACE_Select_Reactor_Token >.

int ACE_FlReactor::register_handler_i (  ACE_HANDLE    handle, ACE_Event_Handler *    handler, ACE_Reactor_Mask    mask )  [protected, virtual]

Register a single <handler>. Reimplemented from ACE_Select_Reactor_T< ACE_Select_Reactor_Token >.

int ACE_FlReactor::remove_handler_i (  const ACE_Handle_Set &    handles, ACE_Reactor_Mask    )  [protected, virtual]

Remove a set of <handles>. Reimplemented from ACE_Select_Reactor_T< ACE_Select_Reactor_Token >.

int ACE_FlReactor::remove_handler_i (  ACE_HANDLE    handle, ACE_Reactor_Mask    mask )  [protected, virtual]

Remove the <handler> associated with this <handle>. Reimplemented from ACE_Select_Reactor_T< ACE_Select_Reactor_Token >.

void ACE_FlReactor::reset_timeout (  void    )  [private]

This method ensures there's an Fl timeout for the first timeout in the Reactor's Timer_Queue.

int ACE_FlReactor::reset_timer_interval (  long    timer_id, const ACE_Time_Value &    interval )  [virtual]

Resets the interval of the timer represented by <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. Reimplemented from ACE_Select_Reactor_T< ACE_Select_Reactor_Token >.

long ACE_FlReactor::schedule_timer (  ACE_Event_Handler *    event_handler, const void *    arg, const ACE_Time_Value &    delay, const ACE_Time_Value &    interval )  [virtual]

Schedule an ACE_Event_Handler that will expire after an amount of time. The return value of this method, a timer_id value, uniquely identifies the event_handler in the ACE_Reactor's internal list of timers. This timer_id value can be used to cancel the timer with the cancel_timer() call. See also: cancel_timer() , reset_timer_interval() Parameters: event_handler  Event handler to schedule on reactor 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 Returns: -1 on failure, a timer_id value on success Reimplemented from ACE_Select_Reactor_T< ACE_Select_Reactor_Token >.

int ACE_FlReactor::wait_for_multiple_events (  ACE_Select_Reactor_Handle_Set &   , ACE_Time_Value *    )  [protected, virtual]

Wait for events to occur. Reimplemented from ACE_Select_Reactor_T< ACE_Select_Reactor_Token >.
