The interesting thing about method Pointers is that their use can be an indication that the code violates the Law of Demeter.
关于方法指针，有意思的事情是：它们的使用可能就表明代码违反了迪米特法则。
Delegates are special types that encapsulate a method, similar to function Pointers found in other programming languages.
委托是封装方法的特殊类型，它类似于其它编程语言中的函数指针。
Method handles act as both function Pointers and as function combinators, allowing a built-in way to construct a call protocol flow from a caller to a callee.
