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 execute a second lambda function based on the outcome of some previous logic. An...

LINQ的基本功能就是创建操作管道,以及这些操作需要的任何状态。 为了富有效率的使用数据库和其他查询引擎,我们需要一种不同的方式表示管道中的各个操作。即把代码当作可在编程中进行检查的数据。 Lambda表达式不仅可以用他们创建委托实例,而且C#编译器也能将他们转换成表
{usingnamespacestd;//The following code declares a lambda expression that returns//another lambda expression that adds two numbers.//The returned lambda expression captures parameter x by value.auto addtwointegers = [](intx) -> function<int(int)>{return[=](inty) {returnx +y; }; ...
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...
CallSite中能够得到MethodHandle,表示方法指针 JVM之后调用这里就不再需要重新解析,直接绑定到这个CallSite上,调用对应的targetMethodHandle,并能够进行inline等调用优化 第一行invokedynamic后面有两个参数,第二个0没有意义固定为0 第一个参数是#2,指向的是常量池中类型为CONSTANT_InvokeDynamic_info的常量。
链接过程通过调用一个boostrap method,传入当前的调用相关信息,bootstrap method会返回一个CallSite,这个CallSite中包含了MethodHandle的引用,也就是CallSite的target。
