Hello Martin,
If the Instantiation for the class is defined to be <i>Private</i>, then you
cannot create the object of the class outside of the class.
=============================================================================
You have asked: <i>Is this a common approach in the abap oo world ? </i>.
There's nothing common or uncommon about it. It depends on what functionality
needs to be achieved.
=============================================================================
<i>Looks strange....why do they do this?</i>
In Java, you can actually make the constructor as private. In ABAP, however,
that is not possible. So this is another way of achieving equivalent
functonality.
=============================================================================
Now you'd like to know <i>Why do they do this...?</i>
That is a reasonably big discussion and cannot possible be explained satisfactorily
in a Forum Post. but I can tell you something: This way of disallowing external
instantiation for a class is the key to implementing OO Design Patterns.
As I had said, you can easily find other weblogs and Forum posts which can introduce
you to what these are.
Regards,
Anand Mandalika.
