What does assignment to *this do (*this = val)?

Question

I was browsing Qt sources, and noticed this

QUuid &operator=(const GUID &guid)
{
    *this = QUuid(guid);
    return *this;
}

I've never seen assignment to "this" before. What does assignment to "this" do?

Answer 1

That is not an assignment to this but to the object pointed by this. That will effectively call operator=( QUuid const & ) on the current object.
