Dealing with EMF model and parser error [message #719252]

Hi,
when there is a parser error in a resource, the EMF model is incomplete.
What is the preferred way to avoid NPEs? Check everything for being not
null, although it should not be null when it is required? Or get to know
that there are parser errors in that resource and cancel the operation?
Is there an easy way to get this information from a Resource?

Hi,
thanks for the link, but I cannot find the answer.
My question was not around loading models. My model is already loaded in
an Eclipse environment, and I want to know how to deal with parser
errors respectivily incomplete models.

Hi,

i actually meant this

Quote:

Potential parse errors are available as resource.getErrors().

Hi,
is there also a way to get validation errors (e.g. parser errors or
constraint violation) from a given IEObjectDescription or
IResourceDescription without loading the resource? The information is
already there, as it is shown in Problems View and Markers...
I get the mentioned objects from the injected IResourceDescriptions,
which is provided by the builder fragment.

Hi Sebastian,

you could try to obtain them from the markers on the IFile that
corresponds to the EMF resource / IResourceDescription.

Sebastian

Thanks, I'm going to try that. I can imagine that it is difficult to
determine if a particular model element is affected. I guess, the text
position can be used somehow.
