Question

我在头文件中有一个名为client的类，所有声明和定义都在头文件中。现在我需要将此类分隔为source和header，但我怀疑构造函数

class client{
  public:
    client(boost::asio::io_service& io_service)
    : stopped_(false),
    socket_(io_service),
    deadline_(io_service)
    {
          stream_buff = TPCircularBufferInit(stream_buff);
    }
 };

如何在源文件上实现此功能。等，

client::client(boost::asio::io_service& io_service){
? // what could be here
? // what could be here
}

Answer 1

该代码也可以写成：

class client{
    public:
        client(boost::asio::io_service& io_service);
};

client::client(boost::asio::io_service& io_service):
    stopped_(false),
    socket_(io_service),
    deadline_(io_service)
{
    stream_buff = TPCircularBufferInit(stream_buff);
}

＆＃34;如何在源文件上实现此功能。像，＆＃34;

您使用与内联定义完全相同的语法：

class client{
  public:
    client(boost::asio::io_service& io_service);
 };

 client:client(boost::asio::io_service& io_service)
    : stopped_(false),
    socket_(io_service),
    deadline_(io_service)
    {
          stream_buff = TPCircularBufferInit(stream_buff);
    }

类构造函数混淆
