Attribute derived from resource uri [message #427315]

Hey,

I expect instances of a certain class to be serialized in a single
resource. Now, instead of giving that class a full-featured 'name'
attribute, I'd want to make 'name' volatile/non-changeable/transient and
derive it from the name of the (file)resource that the object is
contained in. As long as there's no resource, there's no name of course.
Is there anything to watch out for when doing things like this? (I'm
aware I need to take care when the object is moved into a different
resource..)

Thanks,
Felix

Mark it derived as well. Is the object in the root of the resource or
nested deeper? Will you have to consider the case of the resource's URI
being set in addition to moving to a different resource?

Of course.

It's the root.

Good point. At the moment I only set it once.
