All Implemented Interfaces:

public class NamesAreUniqueValidator
extends AbstractDeclarativeValidator

An EValidator implementation, that can be used via ComposedChecks generically to validate for duplicated exported objects.

It validates only the objects, that will be publicly available via an IExportedEObjectsProvider. Local variables and similar objects have to be validated on their own. The INamesAreUniqueValidationHelper provides a convenient way to apply this kind of constraints.
