## 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
  >          }
  >        }
