[news.eclipse.modeling.gmt] Re: [Epsilon]cloning a model element in EOL

[Kimon Polychroniadis <kpolychr@xxxxxxxxx>]

So, let's suppose there is model element A of type TypeOfA , and I wish 
to create a copy.
Isn't it possible to create a copy in a more 'manual' manner, with the 
following the steps below:

1. create a new element e.g. B := new TypeOfA;

2. copy A's attributes and feature values one by one (looping through 
the attributes and features of A, B(.

3. move B in the container of choice.

However, I am not sure as to how I should reference the atttributes and 
features of A (and their values).

I realise the solution (if feasible) is a bit 'brute force' but it's a 
relatively small model I 've got, so I don't think performance would be 
an issue.

Thanks,
Kimon
