Validation API

[Luncher91]

I am currently working on an API which should give the possibility to validate the A2L data.
My first try has been to trigger validation on a per class basis during parsing so it is possible to output the line of the a2l file. But that might not be suffiecient because it might be necessary to validate the data before writing or just at any time after the object structure has been created.

The API should have

• default validators which follow the specification
• the possibility to add custom validators
• validation should easily be possible on a per class basis
• validation of Object structure, A2L data, JSON data
• api to define a custom validation result sink (Default: StdOut/StdErr)
• default validators need to be configurable
  • deactivate specific default validators
  • do/do not fail on validation error
• (nice to have) information about the position in the raw data (A2L, JSON) where the issue has been encountered

Which uses cases do you have for such an API?
Which information would you expect to have during validation?

Please feel free to write down any suggestions regarding this topic!

I worked towards this goal by making the A2L Data iterable. This gave me the possibility to validate all Formula objects in the structure.
I think of a class which iterates once and calls the registered validators for this class.

I therefore dropped the idea about giving the position within the file. It might be enough to locate the issue by printing the validated object.
