In this article, I am going to explain how to create an AWS Lambda function and then call this function from another Lambda function within the same region. This is a useful scenario in which we may need to exe

2:在这里,我们调用后台函数,但也调用返回的lambda (Key point A) Key point A,我们将在这里得到一个编译错误:“参数anotherLambda传递的No值”,因为当我们调用它时,它要求我们向它传递一个参数,这是一种() -> Unit类型。 代码语言:javascript 代码运行次数:0 运行 AI代码解释 background()() // <-- com...
Bootstrap Method: 用户可以自己编写的方法,实现自己的逻辑最终返回一个CallSite对象。 CallSite: 负责通过getTarget()方法返回MethodHandle MethodHandle: MethodHandle表示的是要执行的方法的指针 再串联起来梳理下 invokedynamic在最开始时处于未链接(unlinked)状态,这时这个指令并不知道要调用的目标方法是什么。

A lambda expression can take another lambda expression as its argument. For more information, see "Higher-Order Lambda Expressions" in the articleExamples of lambda expressions. Because a parameter list is optional, you can omit the empty parentheses if you don't pass arguments to the lambda exp...
another // lambda expression as its argument. // The lambda expression applies the argument z to the function f // and adds 1. auto h = [](const function<int (int)>& f, int z) { return f(z) + 1; }; // Call the lambda expression that is bound to h. auto a = h(g(7)...
