 |
|
Hello All,
My apologies if this question is in the FAQ, however, I looked for the FAQ
but couldn't find it. Direction to it would be appreciated. My question is
very simple, can a class have as a return type for one it's methods the type
the class defines? Probably not clear, an example:
class example {
public:
example testfn();
};
example example::testfn() {
}
Is that valid?
Thanks.

Absolutely. Do you experience any problems?

As long as you actually return an object of type
'example', then yes - Not only is it valid, it is
a commonly used construct.

That IS how it is mostly done. But to be able to return an object of
type 'example' from any function (member or not) by value, you must
have a valid copy constructor (explicitly defined or compiler
generated). If you don't know what a copy-ctor is, forget what I just
said :)
