如何在 Julia 中使用锁 [英] how to use lock in Julia

问题描述

我正在与 Julia 合作.IDE 是 Juno.

I'm working with Julia. The IDE is Juno.

如果我是对的，@async 可以生成一个任务，它就像一个线程.
所以我们可以这样做:

If I'm right, @async can generate a task, it's just like a thread.
So we can do this:

@async begin
   # do something1
end
@async begin
   # do something2
end

现在，我需要锁定一个线程.例如，do something1 是将消息推送到列表，do something2 是从同一列表中弹出消息.

Now, I need to lock a thread. For example, do something1 is to push message to a list and do something2 is to pop message from the same list.

这就像 Java 中的 同步.

It's like synchronized in Java.

Julia中的同步是什么?

what is synchronized in julia?

推荐答案

还有一个@sync 宏:

There is also a @sync macro:

帮助?> @sync

等到@async、@spawn、@spawnat 的所有动态封闭使用和@parallel 是完整的.封闭的异步引发的所有异常操作被收集并作为 CompositeException 抛出.

Wait until all dynamically-enclosed uses of @async, @spawn, @spawnat and @parallel are complete. All exceptions thrown by enclosed async operations are collected and thrown as a CompositeException.

@sync @async begin
   # do something1
end

@sync begin
    # some code    
    @async begin
        # do something2
    end
    @async # do something 3
end
