Equals and HashCode in ModelElements [message #839921]

Hi,

I was having a look at the generated model classes and found out
that equals and hashCode aren't implemented.

My problem is:
I have a list of Nodes which have all a attribute id.
To validate the nodes I want to check if every id attribute
is unique. The code I imagine should look like this

INode node1 = ...
INode node2 = ...

node1.equals(node2) == node1.getId().getContent().equals(node2.getid().getContent());

cheers,
Muki

In the upcoming 0.5 release, there is an EqualityService feature that gives model author ability to implement equals() and hashCode() methods. See the enhancements guide for the 0.5 release for more details.
