[ECL] How can I determine a type from a set [message #1353064]

Hi Dimitris,

I have a short question: I need to get the type from a dependency supplier property. I do not know how to determine this. This is the example:

If I print the following to the console:
(Dependency): "self.supplier.println();" I receive a set: "Set {Operation [name = method, ...}". I would like to get the type "Operation" from this set, as I need to compare it against the type of another set.

Can you tell me how to do this, please?

Thanks in advance and kind regards, Alex

Hi Alex,

Does self.supplier.first().eClass().name do the trick?

Cheers,
Dimitris

Hi Dimitris,

yes, it does! Great, thanks! Btw: Would it have been possible to find this out myself via any literature? I have looked closely into the Epsilon book, but did not find the answer you gave me.... Just to be aware Wink

.

Thanks and kind regards, have a nice evening, Alex

Hi Alex,

I'm glad this helped. eClass() is an EMF method - it's worth keeping in mind that all model elements in EMF-based models implement the EObject interface [1] which provides several useful methods (e.g. eClass(), eContainer(), eContents() etc.).

Cheers,
Dimitris
