Interface ValidationProvider

All Superinterfaces:

Validator

All Known Implementing Classes:

BeanValidationProvider, DefaultValidationProvider, EcoreEditorPerformance_PTest.Validation, ValidationProvider.ContextSensitive

public interface ValidationProvider
extends Validator

The ValidationService calls the providers after the validation with EMF. By providing an own provider, one can extend the EMF validation by providing additional validation rules.

As of the 1.23 release, for validation that requires the current view model context, consider using a subclass of the nested ValidationProvider.ContextSensitive class.

1.5
