Hello for everyone.

I'm trying to understand how are saved components of uml models for develop other one project.
I'm starting from Validation View in eclipse window.
My path looks like:
1. ValidationView.fixInstance.perform()
(package org.eclipse.epsilon.evl.dt.views) ->
2. context.getModelRepository().getTransactionSupport().commitTransaction()
(org.eclipse.epsilon.evl.execute) ->
3. model.getTransactionSupport().commitTransaction()
org.eclipse.epsilon.eol.models.transactions ->
4. activeTransactionTree.getTransaction().commit()
org.eclipse.epsilon.eol.models.transactions ->
5. changeRecorder.endRecording()
org.eclipse.epsilon.emc.emf.transactions ->
6. consolidateChanges()
org.eclipse.emf.ecore.change.util ->
7. finalizeChange (for both cases ResourceChange and FeatureChange, EObject )
org.eclipse.emf.ecore.change.util ->
8. EStructuralFeature feature

Am i good understanding, that interface EStructuralFeature collects uml models?

Hi Andril,

I'm not sure I understand what you're trying to achieve or why you need to use transactions. Could you please elaborate a bit more with a concrete example?

> Am i good understanding, that interface EStructuralFeature collects UML models?

This doesn't sound right. EStructuralFeature is an abstract supertype of EAttribute and EReference in Ecore - it doesn't have anything to do with UML.

Cheers,
Dimitris

Thank You for answer.

I want to know where is stored old uml model, with some faults, for future change. Because, i guess, that epsilon stores particular uml in some class.

Is my opinion correct?

Hi Andrii,

Sorry - I don't think I understand what you mean by "store old UML models for future change". Perhaps a minimal example [1] would help clarify things.

Cheers,
Dimitris
