对Go的基本类型和接口介绍完后,我们就可以开始学习reflection的规则(laws)了 The laws of reflection the first law of reflection reflection将interface类型的值转化成reflection对象 Reflection goes from interface value to reflection object 知识点总结 reflect.Value Value.Type() Value.Kind() http://Value.Int(...
The Laws of Reflection (https://blog.golang.org/laws-of-reflection) 简介 Reflection(反射)在计算机中表示程序能够检查自身结构的能力,尤其是类型。它是元编程的一种形式,也是最容易让人迷惑的一部分。 本文中,我们将解释Go语言中反射的运行机制。每个编程语言的反射模型不大相同,很多语言索性就...
The Laws of Reflection 6 September 2011 Introduction Reflection in computing is the ability of a program to examine its own structure, particularly through types; it's a form of metaprogramming. It's also a great source of confusion. In this article we attempt to clarify things by explaining ...
//TypeOf returns the reflection Type that represents the dynamic type of i.//If i is a nil interface value, TypeOf returns nil.func TypeOf(iinterface{}) Type { eface := *(*emptyInterface)(unsafe.Pointer(&i))returntoType(eface.typ) } 当我们调用reflect.TypeOf(x)时,x首先存储在一个...
The first law of reflection 1. Reflection goes from interface value to reflection object. At the basic level, reflection is just a mechanism to examine the type and value pair stored inside an interface variable. To get started, there are two types we need to know about inpackage reflect:Ty...
Go语言反射规则 - The Laws of Reflection 原文地址:http://blog.golang.org/laws-of-reflection ##介绍 反射在计算机的概念里是指一段程序审查自身结构的能力,主要通过类型进行审查。它是元编程的一种形式,同样也是引起混乱的重大来源。 在这篇文章里我们试图阐明Go语言中的反射是如何工作的。每种语言的反射模型...

The 15 Invaluable Laws of GrowthJohn C. Maxwell1. The Law of Intentionality - growth doesn’t just happen正确认识“成长”并非随着年龄增长一个人便会成长,必须有意识地去做。你需要制定成长计划,思考哪些地方是你想要发展的, 你选择你将学习的东西,按照自己的步调和自订的计划去实现成长。从现在开始做!“...
(The earth, like the other planets, is subject to these same laws of movement; it endures a perpetual, internal struggle between its basic elements: the sea and the land seem to be eternally at war, and each instant produces fresh combinations. …… Human beings, dwelling in a place so ...
In the absence of a surface gradient, the new laws of refraction and reflection are ___ the conventional law, so they represent more of an extension than acompleterevolution. A. inferable from B. entailed by C. antithetical to D. coincident with ...
