Hi,
In some cases when my function returns, I need to return a object of
null state. This is when I return object by value.
(Just like for by pointer, I can return a null pointer ).
It has to be equivalent to null (or uninitialized state) , just
like null iterator (or end iterator) .
has someone worked with the concept of a generic null object , i.e
any object with a null object trait can be treated as null object or
like that, with their value comparison semantic etc, so that I dont
need to define a null state for each class I create explicitly.
Thanks
