How to check if an ObjectContext is the root ObjectContext? (has no parent)

Hi all.
How do I check if an ObjectContext is the root ObjectContext, i.e. does not have a parent ObjectContext? Do I simply check if the ObjectContext’s channel is an instance of an ObjectContext to see if it’s a child context?

Cheers,

Yep, still true in 4.0

Hi Hugi,

I believe that's true, at least for 3.1.  I had this lying around somewhere
that seemed to work:

    public static boolean isChildContext(ObjectContext context)
    {
        if (context.getChannel() instanceof ObjectContext)
            return true;
        else
            return false;
    }

mrg
