Default Inheritance and Name hiding

It seems like no body seems to be interested in answering my questions.. nonetheless I shall give it one more try.....

With regards to name hiding.. I have found that it is possible to hide an existing member in the base, simply by redeclaring it in the derived class preceeded by the keyweord 'new'.

I think I understand what it does, but on the other hand I don't see the difference between this and overriding a function.

Instead hiding the member wouldn't redefining it acheive the same thing!?

Some body please answermy question!!

thanx

Replying to my own question.... for the sake of others who might not know....


The difference is that hiding an exsting member done at compile time... whereas overriding occurs at run time... which is why run-time polymorphism may not occur with simply hiding a base member.........

some body correct me if my understanding is wrong...........

You will always find it difficult if you would try to differentiate between the two and yes simply redefining the method with a different name would serve the same purpose.
There are situations where you have to hide the base class definition of a method, otherwise you would always want to use overiding.
