Can you be a bit more explicit (until your book [1] arrives .-).

Say I have (in package foo.model)

---- Candybox.java
/** @model */
interface CandyBox extends EObject {
	/** @model type="Candy" containment="true"*/
	EList getCandy()
}

--- Candy.java
/** @model */
interface Candy extends EObject {
	/** @model */
	String getType();
}

I have used the generated Editor to create the following XML file (in 
meta notation)
<CandyBox>
	<Candy type="sugar bomb"/>
	<Candy type="wine gum"/>
</CandyBox>

Now, in the generated Editor, I write

ResourceSet foo = getEditingDomain().getResourceSet();
/* Now I imagine I should interpret your answer to tell me to */
Adapter bar = adapterFactory.adapt(XXX,YYY); /* adapterFactory is a  	 

                                                generated variable */
CandyBox goo = bar.ZZZ();
Candy moo = bar.XYZ();

Please tell me if I am out in the woods. Any hints to what XXX,YYY, ZZZ 
and XYZ might be would be much appreciated?

XXX I could imagine to be, say, CandyBoxImpl, but that is not visible 
from the editor.
YYY I could imagine to be ModelItemProviderAdapterFactory.java 
(generated, in .edit)
XYZ I could imagine to be getChild (perhaps with another YYY, than 
proposed here).

Thanks,
