Re: why use the 'sealed' ?

Suppose that you have something like this;

public abstract class anAbstractClass
{
public abstract void someMethod();
public abstract void anotherMethod();
}

public class FirstDerivativeClass : anAbstractClass
{
public sealed override void someMethod()
{
}
public override void anotherMethod()
{
}
}

public class SecondDerivativeClass : FirstDerivativeClass
{
public override void anotherMethod()
{
}
}
public sealed class ThirdDerivativeClass : SecondDerivativeClass
{
public override void anotherMethod()
{
}
}


Now you have an abstract class and two abstract methods. At
FirstDerivativeClass, you implement someMethod() and do not want to anybody
to override it. You define it as sealed method. At SecondDerivativeClass you
can not override someMethod() but can override anotherMethod. At
ThirdDerivativeClass you still can override anotherMethod. But you guarantee
that there can not be a fourth derivative class by defining that class as a
sealed. Is it clear?
