Calling a Method in Constructor

Question

Herb Sutter mentions in one of his http://www.gotw.ca articles that an object is constructed(has valid existence) only if the constructor executes completes.ie to put it in

Answer 1

Now from what Herb says, can't we say that since A is not completely constructed inside its constructor Calling f() inside the constructor is invalid as the "this" ptr is not ready yet.

That is only when f() is a virtual method of class A or its inheritance hierarchy and you expect the runtime resolution for f() according to the right object. In simple words, virtual mechanism doesn't kick in if the method is invoked inside constructor.

If f() is not a virtual function, there is no harm in calling it from constructor(s) provided you know what exactly f() does. Programmers usually call class methods like initialize() from constructor(s).

Can you give me the link to the Herb Sutter's article?
