Interface HasControls

  • All Known Subinterfaces:

    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 =, filter, sctls);
       while (elts.hasMore()) {
         Object entry =;
         // 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
