ECORE API example [message #407673]

Hi,

Are there any examples of using ecore API to create an ecore model file
programmatically? Furthermore, can I automate the creation of the
genmodel and generate the code? I am working on a utility to
dynamically create models and corresponding code (model and editors).

Thanks.

The EMF book has a detailled section on this topic (13.6 - Dynamic EMF).
Essentially, there is nothing special about creating Ecore models
dynamically. It's done as for any other EMF model, using the generated
Package and Factory classes.

For example:

EcoreFactory factory = EcoreFactory.eINSTANCE;
EcorePackage package = EcorePackage.eINSTANCE;

EClass libraryClass = factory.createEClass();
libraryClass.setName("Library");

EAttribute numBooksAttribute = factory.createEAttribute();
numBooksAttribute.setName("numBooks");
numBooksAttribute.setType(package.getEInteger());

libraryClass.getEAttributes().add(numBooksAttribute);

// ...

A search on the newsgroup should give plenty of answers to this
question, e.g.:

http://dev.eclipse.org/newslists/news.eclipse.tools.emf/msg2 1057.html

Matt

Besides the awesome pointers from Matt, you can also see several
examples of models built by hand on EMF's JUnit test. Here's an example
http://dev.eclipse.org/viewcvs/index.cgi/org.eclipse.emf/tes ts/org.eclipse.emf.test.core/src/org/eclipse/emf/test/core/d ynamic/SimpleModelTest.java?root=Tools_Project&view=mark up

Cheers,
Marcelo
