We can call functions in a Lua constructor. As Lua function can return more than one value, we can utilize this feature to initialize an element like array with values returned from a function. We're using following functions in the examples discussed below:-- returns no results function ...
To call the constructor, we use constructor chaining. The basic purpose of using abstract classes is to maintain a uniform interface inside all derived classes. This means if there are two classes inheriting from an abstract class, both classes should provide the implementation of a pure virtual...
嗷嗷按,今天被问到在constructor/destructor中调用virtual member function的问题。答错了,很羞耻。 依稀记得在constructor/destructor调用virtual member function不好,就随口答道不能调用,可能会出错。 后来仔细想想不对,羞耻呀。调用是可以的,从语言角度没错,只不过和其他情况下调用虚函数有些不同。
