编译器是如何针对虚函数产生可以再运行时刻确定被调用函数的代码呢？也就是说，虚函数实际上是如何被编译器处理的呢？Lippman在深度探索C++对象模型[1]中的不同章节讲到了几种方式，这里把“标准的”方式简单介绍一下。 我所说的“标准”方式，也就是 ...

My memory on this is a little sketchy, but I think that when you make a call on a virtual function, the virtual function table must be consulted before method invocation, whereas non-virtual functions ...

In object technology, a function that has a default operation for a base class, but which can be overridden and perform a different operation by a derived class. A derived class inherits the ...

I ask because it doesn't seem to be for me. I've got a number of classes that inherit from a base class with some virtual functions. When I have a base class pointer everything works fine as it should ...

Embedded C developers shy away from C++ out of concern for performance. The class construct is one of their main concerns. My previous article Code Craft – Embedding C++: Classes explored whether ...
