| Serializing a list of any type [message #409760] |

Hi,
I would like to create an EObject with an attribute called allMyObjects.
This attribute would be used to store any type of objects i.e.: EObject,
EList, String, Integer, Long, Date etc.
I thought of modeling this with a "to many" relation of EJavaObject but I've
found out that EJavaObject are not serialized by Resources.
What are the options when it comes to modeling a list of any type and have
this list saved and retrieved from at Resource?
Thanks
Jean-Claude

Jean-Claude,
In EMF 2.3 we've made EJavaObject a serializeable EDataType, but it's
implemented to use java.io.Serializeable, so the resulting serialization
is not human readable and is extremely verbose. It might be better use
an multi-valued EReference to EObject and then serialize EObjects that
are instances of SimpleAnyType which is very similar to Java's wrapper
types for primitives, i.e., an Integer is a java.lang.Object, but an int
is not. This search page is a great place to look up previous answers

I've searched for the SimpleAnyType and that's what I would need.
However I do I specify this in the Ecore Model Editor. Seems like a bit =
of a dumb question but the GUI that I have does not seem to have the =
SimpleAnyType option. I'm using EMF 2.1.

JC,
You'd need to load the XMLType.ecore model, which is in
org.eclipse.emf.ecore/model/XMLType.ecore, and that should make all of
it's classifiers available.
