First, we will discuss the meaning of an abstract class and then the pure virtual function in C++. Afterward, we will see the practical implementation of the abstract class in C++ and the limitations of this typ

PURE_VIRTUAL作用:一个继承自UObject的UClass都是必须能够实例化的,系统要能够调用其默认构造函数,即所谓的CDO(Class Default Object),这样他就不能含有纯虚函数,但是某些特定场景中要求他的虚函数在其子类中被强制实现(而不是普通虚函数的可选实现),那么此时可以使用PURE_VIRTUAL,这样他的cpp文件中可以不用实现此函...

On the other hand, we have the concept of pure virtual functions, which are declared similar to the regular virtual functions and include the notation = 0; at the end of the declaration. These functions essentially don’t have a definition in the base class, where they are declared first....
有了这些基础,作者然后列出了5中可能出现"pure virtual function call"的情况。 http://www.artima.com/cppsource/pure_virtual.html 有空再将其翻译出来学习下。 本文的基本观点引自:http://www.debuggingnow.com/blog/2010/03/pure-virtual-function-call-in-cpp.html...
