[EMF] The purpose of Injector and Extractor? [message #766076]

Hi all pioneers,

I'm a newbie to the EMF and I have some questions about the purpose of injector and extractor...

As to my knowledge to the injector and extractor, they are classes that transform xmi files to a model (injector) and a model to xmi (extractor)? Are they correct? Or they are not designed to do such things?

Also, I am confused about the injector method:

public void inject(IModel targetModel, String strSource)

I traced the code that when I run an ATL transform, the transform actually run inject 3 times -- At the first time, strSource is my IN ecore path, and second time, strSource is my IN xmi file, and third time, strSource is my OUT ecore path... (The code that I traced is EMFInjector)

So that I'm confused about the purpose of this inject method... could anyone please help explaining me about this? Or pointing out a clear document location to read?

Thank you in advance.

Please post to the eclipse.modeling.m2m forum and include [ATL] as the
start of your subject line.
