setTimeOut和本地函数 [英] setTimeOut and local function

问题描述

我正在使用Ax 4.0

I'm working on Ax 4.0

我试图在具有局部功能的作业中使用Object.setTimeOut方法，如

I'm trying to use the Object.setTimeOut method in a job with a local function, as stated in the msdn documentation :

static void setTimeOutJob()
{
    Object o = new Object();

    void printText()
    {
        ;
        info( "2 seconds has elapsed since the user did anything" );
    }
    ;
    // Set a Time Out with the idle flag set to false
    o.setTimeOut(identifierstr(printText), 2000, false);
}

但是这个简单的工作不会产生任何结果，因此看来我在这里缺少了一些东西.

But this simple job doesn't produce anything, so it seems I'm missing something here.

有人为此工作吗?

推荐答案

setTimeout方法不适用于作业中的本地功能.

The setTimeout method does not work with a local function in a job.

有关工作示例，请查看表单tutorial_Timer.

For a working example have a look on the form tutorial_Timer instead.

更新:

setTimeout方法是一个魔术"函数，但是不会将AX变成多线程环境.

The setTimeout method is a "magic" function, but it does not turn AX into a multithreading environment.

它仅在Windows 事件循环起作用时起作用.在AX上下文中，这意味着表单正在运行，而其他人正在等待表单完成. sleep函数不符合条件.

It only works while a Windows event loop is in action. In the AX context it means that a form is running and someone else is waiting for the form to complete. The sleep function does not meet the criteria.

该对象还必须是活动的"，调用垃圾回收对象是不好的！

Also the object must be "alive", calling a garbage collected object is no good!

示例(基于类):

class SetTimeoutTest extends Object //Yes, extend or it will not compile
{
    str test;
}

public void new()
{
    super();
    test = "Hello";
}

public str test()
{
    return test;
}

protected void timedOut()
{;
    test = "2 seconds has elapsed since the user did anything";
    info(test);
}

static void main(Args args)
{
    SetTimeoutTest t = new SetTimeoutTest();
    FormRun fr;
    ;
    t.setTimeOut(methodStr(SetTimeoutTest,timedOut), 2000, false);
    //sleep(4000); //Does not work
    fr = ClassFactory::formRunClassOnClient(new Args(formstr(CustGroup))); //Could be any form
    fr.init();
    fr.run();
    fr.wait(); //Otherwise the t object runs out of scope
    info(t.test());
}
