This factory reports the Class of objects that it is creates as 29 * well as the objectClass corresponding to that Class. This makes it easier 30 * for the server side provider to lookup the respective factory rather than 31 * attempt several others within the list of object factories in the order of 32 * greatest specificity. JNDI SPI methods are inefficient since they are 33 * designed to try all object factories to produce the object. Our provider 34 * looks up the most specific object factory based on this additional 35 * information. This makes a huge difference when the number of ObjectFactory 36 * instances is large. 37 * <p/> 38 * Eventually, it is highly feasible for generated schemas, to also include 39 * state and object factories for various objectClasses, or domain objects. 40 * This means the number of factories will increase. By associating object and 41 * state factories with their respective objectClasses and Classes we can 42 * integrate these DAOs into the schema subsystem making factory lookups 43 * extremely fast and efficient without costing the user too much to create and 44 * store objects within the directory. At the end of the day the directory 45 * becomes a hierarchical object store where lookup, bind and rebind are the 46 * only operations besides search to access and store objects. That's pretty 47 * PHAT! 48 * 49 * @author <a href="mailto:dev@directory.apache.org">Apache Directory Project</a> 50 * @version $Rev: 679219 $ 51 */ 52 public interface ServerDirObjectFactory extends DirObjectFactory 53 { 54 /** 55 * Gets either the OID for the objectClass or the human readable name for 56 * the objectClass this DirStateFactory is associated with.
