ACE学习简单记录

一.ACE_Reactor的使用方法

1.创建ACE_Event_Handler的派生类。

?

1 2 3 4 5 6 7 8 9 10 11 12 13

class MyHandler : public ACE_Event_Handler { public:     MyHandler(                      // ...                   )                    :ACE_Event_Handler()     {          // ...     }           // ... }

2.重写一个可以被ACE_Reactor调用的方法。

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21

int handle_timeout ( const ACE_Time_Value &current_time,const void * = 0) {     // ... }   // or     int handle_signal ( int signum, siginfo_t * = 0, ucontext_t * = 0 ) {     // ... }   // or   int handle_input( ACE_HANDLE fd = ACE_INVALID_HANDLE) {     // ... }   // or

3.实例化一个自定义的派生类，通常发生在main()函数中。

?

1	MyHandler * handler = new MyHandler();

4.关联自定义的handler和Reactor。

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19

ACE_Time_Value initialDelay(3); ACE_Time_Value interval(5); ACE_Reactor::instance()->schedule_timer( handler,                                                                      0,                                                                      initialDelay,                                                                      interval);   // or   ACE_Sig_Set signalSet(1); ACE_Reactor::instance()->register_handler(signalSet,                                                                      handler);   // or   ACE_Reactor::instance()->register_handler(handler,                                                                      ACE_Event_Handler::READ_MASK);   // or

5.启动Reactor即可

?

1	ACE_Reactor::instance()->run_reactor_event_loop();
