How do I call a parent class's overidden method?

module test;

abstract class SuperClass {
    public pure void methodA() {

    }
}

class SubClass {
    public override pure void methodB() {
        // How do I call the parent methodA() from here?
    }
}

super.method

so

abstract class SuperClass {
    public pure void methodA() {

    }
}

class SubClass : SuperClass {
    public override pure void methodA() {
        // calls the parents
        super.methodA();
    }
}


To do it from outside the class, you write the class name:


void main() {
        auto obj = new SubClass();
        obj.SuperClass.methodA(); // calls the specific super method
}

Submit a bug to the bugtracker with "[dox]" in its subject line. This is the only way to guarantee the docs will improve.

http://dlang.org/function#virtual-functions
=========================

To avoid dynamic binding on member function call, insert base class name before the member function name. For example:

...


void main() {
  auto d = new D();
  assert(d.foo() == 3);    // calls D.foo
  assert(d.B.foo() == 1);  // calls B.foo
  assert(d.C.foo() == 2);  // calls C.foo
  d.test();
}

=========================
