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
>             }
>        }
