Validation just for the changed elements? [message #820676]

Hi,

I got some validations which cause much cpu usage at the runtime (calculating permutations for logical expressions). Thats why i am asking if there is a way to tell the validator "just execute this validation for the element after some change inside the element was done".

At the moment the validator runs every time i change 1 sign anywhere in the document -> And then he checks all validations.

My fear is, that if my file gets longer and longer and longer -> That there will be a real problem with the cpu load.

So ... is there a way to change the way of validation?
Hope there is one! :>

Thanks in advance!

Hi Heinz,

no there is no infrastructure for that. You may want to execute your
validation only on save (see param for @Check annotation).
Did you profile your check implementation. Maybe there is something
unexpected going on under the hood?

Sebastian

Hi Sebastian,

first of all thank you for your answer.

The function i wrote is okay. I checked it very often now.
And with a normal amount of using this validation everything is very fine.
I am just worried about the case when there are about 200 things which will be validated in this way.
So i thought of just let the validation happen when something is changed. But if Xtext couldn't do this at the moment, i have to stay worried until this feature is implemented Smile

The solution with the validation before saving is not the way i wanted it.
I'll give it a try, but i don't think that this is perfect for my use case.

Thanks again for the very quick help!! Smile
