boost - 如何在类定义中声明多个截止时间计时器？

Question

我设法在课堂上声明了一个截止日期计时器。

class myTimerService
{
public:
    boost::asio::io_service ioService;
    myTimerService():t0(ioService){}
private:
    boost::asio::deadline_timer t0;
};

所以构造能够构造t0。如何修改它以具有另一个截止时间_计时器 t1。后续的构造会是什么样子？

class myTimerService
{
public:
    boost::asio::io_service ioService;
    myTimerService()-------????
private:
    boost::asio::deadline_timer t0;
    boost::asio::deadline_timer t1;
};

Answer 1

正如评论者所说，基本和成员初始化列表以逗号分隔：

#include <boost/asio.hpp>
class myTimerService {
  public:
    boost::asio::io_service ioService;
    myTimerService() : t0(ioService), t1(ioService) {}

  private:
    boost::asio::deadline_timer t0;
    boost::asio::deadline_timer t1;
};

但是，我建议NSMI：

#include <boost/asio.hpp>

class myTimerService {
    boost::asio::io_service     ioService;
    boost::asio::deadline_timer t0{ioService}, t1{ioService};
};
