Package: get EClass by name? [message #503115]

Hi,

is there a way to get an EClass returned from the Package by giving it
the name of the class as a String?

Example: I have the String "InputEvent" and want to get the EClass
InputEvent from my package. I've seen that there are methods like
'Package.eINSTANCE.getInputEvent()' which returns the EClass InputEvent.
So I could use that method and a Mapping<String, EClass> to map every
String to its corresponding class, but a method like 'getEClass(String
eClassName)' would be more comfortable.

Is there anytinhg like that?

Thanks,
Matthias

Hi Matthias,

An EClass is an EClassifier, hence you can call:

eClass = (EClass) ePackage.getEClassifier("MyClass");

I have a followup question. How can I get the related ePackage from a class name?

Thanks,
Roza

Roza,

Different packages can have classifiers for the same class name, so
there isn't a general one-to-one mapping from class name to classifier.
