Refering to subclass from abstract class

i have a problem with my abstract class not knowing, which subclass calls its constructor.

abstract class A {

    Field field;

    public A() {
        this.field = Manager.add(Here i would like to add the type of subclass);
    }
}

I could carry the class-type as a parameter in a chain of constructors, but i was wondering if there is a different way.
Maybe I could use the StackTrace to find out about the subclasses and get their type, but i don't think it should be used this way.

Thank you very much in advance for your answers :)
