Can I override implementation of interfaces in inherited classes ?


interface xyz
{
    	void doSomething();
}

class abc: xyz
{
    	void doSomething()
    	{
    	    	// do something
    	}
}

class ijk : abc
{
    	override void doSomething()
    	{
    	    	super();
    	    	// do more things
    	}
}

This is powerfull.
Even besser then Delphi Object Pascal Implementation.

I think Delphi, as well as C++ and Java all
allow this.

By the way, shouldn't it be this:

class abc: Object, xyz  // Inherit from Object
{
    void doSomething()
    {
        // do something
    }
}

Or is Object automatically assumed as ancestor
when the first 'class' in the inheritance list
is in fact an interface?

Delphi, don't allow inherited interfaces be overrided.
I do not know how Java does...

I thought it does as long as the implementing
method is defined as public or protected?
I can hardly imagine this would not be possible!
