Question

I have such design:

public interface MyInterface {
    public abstract List<Sth> getSth();
}

public class MyConcreteImplementation implements MyInterface {
    private ConcreteSth mSth = new ConcreteSth();

    public List<Sth> getSth(){
        return mSth.getSth(additionalParams); 
    }
}

Purpose of code above is to provide unified method to be called from other classes.

Can this be called a pattern? If so how to name it?

Answer 1

Adapter

Purpose of code above is to provide unified method to be called from other classes.

That’s really sound like Adapter. You want to have a certain class adapted to your interface. The interface here is MyInterface and the adaptee is ConcreteSth.
