Question

Say, classes A1,A2,…,An all extends the abstract class B.
I would like A1,…,An to have a function that returns a string of the class name.
This is certainly known in compile-time, but I would like to implement this function in
B, and use inheritance so that all Ai:s get this functionality.

In java, this can easily be done, by letting B have the method

String getName() {
    return this.getClass();
}

more or less. So, how do I do this in D? Also, is there a way, using traits or similar, to determine which class members are public?

Answer 1

simply typeof(this).stringof

however this is fixed at compile time so inheritance doesn’t change the value

this.typeinfo.name

will give the dynamic name of the classname of the instance
