Interface HasControls

All Known Subinterfaces:: UnsolicitedNotification

public interface HasControls

This interface is for returning controls with objects returned in NamingEnumerations. For example, suppose a server sends back controls with the results of a search operation, the service provider would return a NamingEnumeration of objects that are both SearchResult and implement HasControls.

 NamingEnumeration elts = ectx.search((Name)name, filter, sctls);
 while (elts.hasMore()) {
 Object entry = elts.next();
 // Get search result 
 SearchResult res = (SearchResult)entry;
 // do something with it 
 // Get entry controls
 if (entry instanceof HasControls) {
 Control[] entryCtls = ((HasControls)entry).getControls();
 // do something with controls
 }
 }
