XAF ships with the Business Class Library that contains a number of persistent classes ready for use in your applications. All these classes derive from the BaseObject base persistent class declared in the same library. This is a recommended-to-use f…

派生类访问模板基类(templatized base class)命名 本文地址: http://blog.csdn.net/caroline_wendy/article/details/23993691 派生类继承模板化基类的成员函数, 默认是无法訪问, 模板化基类的命名. 原因是模板的定制化有可能取消某些函数, 为了能在编译期检測出错误, 所以默认无法訪问. 派生类訪问模板化基类, 包括三种方法: 1. 调用基类函数时, 使用"this->", 指明调用的类, 是本类, 在编…

1.为什么C++中不允许类的大小是0 class ZeroSizeT {}; ZeroSizeT z[10]; &z[i] - &z[j]; 一般是用两个地址之间的字节数除以类型大小而得到的,而类型大小是0将会出问题 2.为什么有时多个类组成实例所占空间都是一样的 class Empty { }; class EmptyToo : public Empty { }; class EmptyThree : public EmptyToo { }; sizeof(Empty) : 1 size…

We have a form component: <label> <h3>Type</h3> <workout-type formControlName="type" ></workout-type> </label> form = this.fb.group({ name: ['', Validators.required], type: 'strength' }); constructor( private…

Preloading all modules is quite an extreme approach and might not always be desirable. For instance, you don't want to preload lazy routes a user might not even have access to. Therefore, in this lesson we're going to have a look at how to define a c…

uvm_object,是所有uvm data和hierarchical class的基类,实现了copy,compare,print,record之类的函数 扩展类中必须实现create和get_type_name函数,get_type函数. uvm_object从uvm_void中扩展出来,uvm_void是一个virtual class,不包含任何其他东西. 声明了一个static类型的变量 uvm_status_container    __m_uvm_status_container:…

完全参考自:<C++ Templates The Complete Guide>e_CN,p_281 16.2 空基类优化 最近周围有点吵,论文没看进去,随便翻了本书…… 下文没有多大意义,只是解决了自己的一个疑惑. 1.为什么C++中不允许类的大小是0 class ZeroSizeT {}; ZeroSizeT z[]; &z[i] - &z[j]; 一般是用两个地址之间的字节数除以类型大小而得到的,而类型大小是0将会出问题 2.为什么有时多个类组成实例所占空间都是一样的 c…
