validate

public void validate(RoleValidator.RoleConfig config,
                     Errors.Collector collector,
                     ProviderRequest request)

supportedAnnotations

public Collection<Class<? extends Annotation>> supportedAnnotations()

Description copied from interface: AbacValidator

Provide extension annotations supported by this validator (e.g. RolesAllowed). Annotations will be collected according to framework in use. For JAX-RS, annotations from application class, resource class and resource methods will be collected. The annotations will be transformed to configuration by AbacValidator.fromAnnotations(EndpointConfig).

Specified by:

supportedAnnotations in interface AbacValidator<RoleValidator.RoleConfig>

Returns:

Collection of annotations this provider expects.
