如何传递参数到Thread对象？ [英] How to pass parameters to a Thread object?

问题描述

我使用一个C ++类库提供了一个Thread基类，用户必须
实现一个 run（）方法。 / p>

有没有推荐的方法如何传递参数到 run（）方法？现在
我更喜欢通过构造函数（作为指针）传递它们。

解决方案

C ++，但是这就是你在Java中做的。你会有一个类扩展Thread（或实现Runnable）和一个构造函数，你想要传递的参数。然后，当你创建新的线程，你必须传入参数，然后启动线程，像这样：

  Thread t = new MyThread（args ...）; 
 t.start（）; 
  

在您的情况下必须相同。

I'm working with a C++ class-library that provides a Thread base-class where the user has to implement a run() method.

Is there a recommended way on how to pass parameters to that run() method? Right now I prefer to pass them via the constructor (as pointers).

解决方案

I'm not sure about C++, but that's how you would do it in Java. You'd have a class that extends Thread (or implements Runnable) and a constructor with the parameters you'd like to pass. Then, when you create the new thread, you have to pass in the arguments, and then start the thread, something like this:

Thread t = new MyThread(args...);
t.start();

Must be the same in your case.
