1. Unified Type System Scala has a unified type system, enclosed by the type Any at the top of the hierarchy and the type Nothing at the bottom of the hierarchy. All Scala types inherit from Any. # Using Any, Book extends AnyRef, and x is an Int that…

Once again, in this series of posts I look at the parts of the .NET Framework that may seem trivial, but can help improve your code by making it easier to write and maintain. The index of all my past little wonders posts can be found here. We've seen…

We can create the most basic components of our GraphQL Schema using GraphQL's Object Types. These types allow us to group related fields together under a specific type, such as a Video or a User, and then allows us to fetch these types when we query…

RTTI(Run-Time Type Information,通过运行时类型信息)程序能够使用基类的指针或引用来检查这些指针或引用所指的对象的实际派生类型. RTTI提供了以下两个非常有用的操作符: (1)typeid操作符,返回指针和引用所指的实际类型. (2)dynamic_cast操作符,将基类类型的指针或引用安全地转换为派生类型的指针或引用.  面向对象的编程语言,象C++,Java,delphi都提供了对RTTI的支持. 本文将简略介绍 RTTI 的一些背景知识.描述 RTTI 的概念…

elasticSearch 的中文文档 http://es.xiaoleilu.com/010_Intro/05_What_is_it.html https://www.elastic.co/blog/index-vs-type Who has never wondered whether new data should be put into a new type of an existing index, or into a new index? This is a recurring qu…

This section deals with more theoretical aspects of types. A type system is a set of rules used by a language to structure and organize its collection of types. We use the term object (or data object) to denote both the storage and the stored value.…

The "any" type can be very useful, especially when adding types to an existing JavaScript codebase, but it can also lead to lots of runtime errors, as it provides no type-checking. The "unknown" type on the other hand, restricts develo…

类型转换是一种检查类实例的方式,并且哦或者也是让实例作为它的父类或者子类的一种方式. Type casting is a way to check the type of an instance, and/or to treat that instance as if it is a different superclass or subclass from somewhere else in its own class hierarchy. 类型转换在Swift中使用is 和 as操作符实现.…

Runtime type information (RTTI) allow you to discover and use type information while a program is running This take two forms: 1. "traditional" RTTI, which assumes that you have all the types available at compile time, 2. the reflection mechanis…
