计时器的打开和关闭封装

自己写的简单计时器&＃xff1a;程序開始之后2秒钟之后运行第一次到时触发的动作&＃xff0c;以后每隔一秒钟都会运行同样的动作&＃xff1b;当运行总次数到达3次之后就终止计时&＃xff0c;整个程序退出&＃xff0c;并停止事件监听&＃xff0c;释放资源

#include
#include "ace/Log_Msg.h"
#include "ace/Event_Handler.h"
#include "ace/Reactor.h"
#include "ace/Thread_Manager.h"bool stop_event_loop &＃61; false;//是否须要终止计时器服务class My_Timer_Handler : public ACE_Event_Handler
{
public:My_Timer_Handler(const int delay,const int interval);~My_Timer_Handler();int handle_timeout(const ACE_Time_Value& , const void *act /* &＃61; 0 */);//计时器到期后运行的回调函数
private:int n_;//循环计时的次数long time_handle_;//在计时器队列中的ID
};My_Timer_Handler::My_Timer_Handler(const int delay,const int interval):n_(0)
{std::cout<<"My_Timer_Handler()"<reactor(ACE_Reactor::instance());this->time_handle_ &＃61; this->reactor()->schedule_timer(this,//在这里注冊定时器0,ACE_Time_Value(delay),//程序一開始延迟delay秒開始首次运行到期函数ACE_Time_Value(interval));//循环计时&＃xff0c;每隔interval秒反复运行
}My_Timer_Handler::~My_Timer_Handler()
{std::cout<<"~My_Timer_Handler()"<}int My_Timer_Handler::handle_timeout(const ACE_Time_Value& , const void *act /* &＃61; 0 */)
{if (&＃43;&＃43;this->n_>3){ACE_Reactor::instance()->cancel_timer(this->time_handle_);stop_event_loop &＃61; true;std::cout<<"cancle_timer"<}int main(int argc, char* argv[])
{My_Timer_Handler my_handle(2,1);while (true){if (stop_event_loop){std::cout<<"stop handle time"<handle_events();}return 0;
}


执行结果例如以下&＃xff1a;

My_Timer_Handler()
my timer handler handled timeout
my timer handler handled timeout
my timer handler handled timeout
cancle_timer
stop handle time
~My_Timer_Handler()
请按随意键继续. . .
