Hi All,

We use Diagnostician.INSTANCE.validate() method if we manually want to trigger the editor.

Is it possible to filter it for error types?

I mean to say, can we validate only the validations which produces errors but not warnings ?

Thanks for any help Smile

Hi,

no you have to build that yourself. (maybe you can abuse the existing IssueSeveritiesProvider/ConfigurableIssueCodesProvider/IssueSeverities for that)

what is the reason for doing that?

Hi Christian,
Thanks for your reply.

Actually I have 2 grammars , one with extension .model1 and second one with .model2.

.model2 files refer data from .model1 files.

And suppose, if .model1 files have errors then I do not want to continue generation for .model2 file.

I detect these problems by calling Diagnostician.INSTANCE.validate() method from validator class of .model2 file for the referred content of .model1 files.

So at this stage, if .model1 files have errors, I notify this in .model2 file saying that the referred file has errors OTHERWISE it continues generating outputs which ends up in many problems/exceptions.

So I needed this.

Do you see a better approach than this ?

Regards,
Arshad

Hi Arshad,

you may want to use the IResourceValidator instead of the diagnostician
singleton. The resource validation will also include errors on the
resource level and configure the diagnostician properly before it
invokes that one.

Best,
Sebastian

Hi Sebastian,

Thanks for your reply.

But is there any execution time related differences between IResourceValidator and Diagnostician ?

Regards,
Arshad

I don't understand the question. What do you refer to by 'execution-time
related'? The IResourceValidator will provide the correct result while
Diagnostician.INSTANCE will not provide the correct result, e.g. it
misses all Resource.getErrors

Sebastian
