java中lambda接口一览

1、java中标准定义的用于操作数据的lambda接口都在 package java.util.function; 这个包里面,这些接口都不是用来给你在别的类里面实现的,虽然实现了也没什么关系。 2、lambda的写法实际上是逆反面向对象编程这种思想的,因为在编程中它直接提现了数据的处理的逻辑。 之 ......

c++lambda引用捕获的陷阱思考

### 值传递与应用传递概念 1. = 值传递:使用=来捕获外部变量时,lambda表达式会复制外部变量的值到lambda内部,以供后续使用。这意味着lambda函数内部使用的是外部变量的副本,对副本的修改不会影响外部变量本身。 2. & 引用传递:使用&来捕获外部变量时,lambda表达式会捕获外 ......
