invoke是C++17标准引入的一个函数模板,用来调用可调用对象(Callable Object,如函数指针、函数对象、成员函数指针等)并返回结果。 invoke提供了统一的调用语法,无论可调用对象的类型是什么,都可以使用同一种方式进行调用。 详见:https://en.cppreference.com/w/cpp/utility/functional/invoke ...
A function is a block of code that performs some operation. A function can optionally define input parameters that enable callers to pass arguments into the function. A function can optionally return a value as output. Functions are useful for encapsulating common operations in a single reusable ...
