Quick solutions to common questions related to Epsilon.

How do I get all children of a model element?

Epsilon does not provide a built-in method for this but you can use EObject's eContents() method if you're working with EMF. To get all descendants of an element, something like the following should do the trick: o.asSequence().closure(x | x.eContents()). See https://www.eclipse.org/forums/index.php/t/855628/ for more details.

How do I get the container of a model element?

Epsilon does not provide a built-in method for this but you can use EObject's eConainer() method if you're working with EMF.

How can I use an existing EMF Resource in Epsilon?

To use an existing EMF Resource in your Epsilon program, you should wrap it as an InMemoryEmfModel first.

How can I validate/transform Archi models using Epsilon?

To use Archi (http://www.archimatetool.com/) models within Eclipse, you need to install the Archi plugins from https://github.com/archi-contribs/eclipse-update-site. You can then use Archi models in Epsilon in the same way that you'd use any other EMF-based models.
