Multiple Validation Classes -- Dynamic [message #1002422]

In thread Using multiple providers there is an explanation how to use multiple Validator classes:

@ComposedChecks(validators={V1.class, V2.class})
public class MyDslJavaValidator extends AbstractMyDslJavaValidator {

}

This works fine if the validation classes are known at compile time. I now have a situation where additional validator classes are defined by new bundles that represent components of the DSL. Each component comes with its own validators. The validator classes are therefore not known at compile time.

Is there a way to easily add such validator classes at runtime to the main Xtext validator?

Regards, Jos

Hi Jos,

we had the same problem. Our solution was to use the extension point org.eclipse.ui.startup to call a method on startup of the new bundle which then registers the new validator(s) with the EValidatorRegistrar.

Is there any better solution?

Best regards,

Tim

You may want to override
org.eclipse.xtext.validation.AbstractInjectableValidator.register(EValidatorRegistrar)
and read the additional validators from an extension point.

Sebastian
