静态类&穿线 [英] static classes & threading

问题描述

你好，


我有一个包含多个

线程调用的所有静态方法的类。我想知道这对竞争线程有什么影响。

Thread2是否必须等到Thread1完成后才能使用

StaticClass.Method1才能使用它？ />

如果我删除静态方法并使所有线程实例化

它自己的类副本怎么办？这会消除等待的争用吗？


谢谢。

Hello,

I have a class with all static methods that is called by multiple
threads. I was wondering what effect that has on the competing threads.
Does Thread2 have to wait until Thread1 is done with the
StaticClass.Method1 before it can use it?

What if I removed static methods and made all the threads instantiate
its own copy of the class? Would that remove the waiting contention?

Thanks.

推荐答案

这就是多线程:)所以除非在你的方法中有一个

互斥锁，否则第二个线程将不会等待

第一个线程来完成静态方法的执行。 />

That''s the whole point of multithreading :) So unless there is a
mutual-exclusion lock in your method the second thread will not wait for the
first thread to finish executing the static method.

我还不清楚。假设静态方法DoSomeTask创建一个

连接对象并获取一些数据，然后销毁连接。

然后让我们说2个线程调用DoSomeTask。第二个帖子是否会等待第一个帖子完成？


问候

I am still not clear. Let''s say the static method DoSomeTask creates a
connection object and gets some data, then destroys the connection.
Then let''s say 2 threads call DoSomeTask. Will the second thread have
to wait for the first thread to complete?

没有第二个线程也会创建一个连接对象并获取一些数据

，而第一个线程仍在获取一些数据。

静态方法和非静态方法之间的区别在于静态方法属于

非静态方法属于类实例的类型。

No the second thread will also create a connection object and get some data
while the first thread is still getting some data. The difference between a
static method and a non-static method is that the static method belongs to
the type where the non-static method belongs to an instance of a class.
