How can i poof an elis datat? [message #423362]

Hello,

I have an Elist like this. EList<Property> Pi

Now i fill this EList with some Elements. But i want to proof these
Elements dynamically. So is there a way to get the information, that
this elist only holds propertys?

This is only an example, there are some more lists, whiches holds other
elements.

Greetings
Jörg

Jörg, I'm curious: Which non-Property classed objects do you think would
Java allow you to add to such a list?

There is no non-property class i can at. I know this. this is the reason
i want to proof it, before i call the put method.

I still don't understand. Why do you want to proof something that you
already know?

The lists for multi-valued properties implement
EStructuralFeature.Setting and hence can be cast to that. From there
you can find out the feature and hence the type of the feature...

Ah, do you mean how to test if a given object "is a" Property?
That would be a pure Java question and I'd say

if (object instanceof Property) list.add((Property)object);
