How to make an element transient? [message #508479]

I have an xml that looks like this-
<parent type="x">
<child type="a"/>
<child type="b"/>
<child type="c"/>
</parent>

I have generated the ecore for that from the schema and I have an emf model from that.

At runtime on my emf model, I would like to make a specific child object (say <child type="b">) transient so that it is not serialized.

How do I go about doing that?
I tried childObject.eContainmentFeature().setTransient(true) where childObject is an instance that has type="b".
But that makes all the child objects as transient (i.e disappear when I serialize).

So I get -
<parent type="x"/>

Thanks,
Karthik

Karthik,

You can't make individual objects transient.

Thanks. I realized later that transient is a property of the feature and not of the individual objects. Should have realized that before posting the question. Razz
