I'm reading http://www.digitalmars.com/d/2.0/declaration.html#Typeof
where it says:
"typeof(this) will generate the type of what this would be in a
non-static member function, even if not in a member function. "
From that I got the impression that the code below would print the
same result, but it doesn't. It prints:
main.Bar
main.Foo
instead of:
main.Foo
main.Foo
Is this a bug or have I misunderstood the docs?
module main;
import std.stdio;
class Bar
{
void method ()
{
writeln(typeid(typeof(this)));
writeln(typeid(this));
}
}
class Foo : Bar {}
void main ()
{
auto foo = new Foo;
foo.method;
}
I don't think it's a bug. More of it, Expressions page in the docs has
your very same example in Typeid section.
Inside Bar.method, typeof(this) yields a type (Bar), and typeid for
types gets you, well, typeid for types :) typeid(this), hovewer, should
get typeinfo for most derived class, which it does.
