Why not just pass in the map of 32 * normalizers to these parsers and let them use that? First off this mapping 33 * will not be static when dynamic updates are enabled to schema. So if 34 * we just passed in the map then there would be no way to set a new map or 35 * trigger the change of the map when schema changes. Secondly we cannot just 36 * pass server side objects that return this mapping because these parsers may 37 * and will be used in client side applications. They will not have access to 38 * these server side objects that generate these mappings. Instead when a 39 * resolver is used we can create mock or almost right implementations. 40 * 41 * @author <a href="mailto:dev@directory.apache.org">Apache Directory Project</a> 42 */ 43 public interface NormalizerMappingResolver<E extends Normalizer> 44 { 45 Map<String, E> getNormalizerMapping() throws Exception; 46 }
