Method Detail

advise

public static int advise(org.omg.CORBA.Object source,
                         java.lang.String id,

Advise an event source of your interest in its events. This example shows how to advise a com.sas.iom.SAS.ILanguageService object of interest in com.sas.iom.SASEvents.ILanguageEvents events.

 ILanguageServices iLang = iWork.LanguageService();
 String eventID = ILanguageEventsHelper.id();
 ILanguageEventsOperations eventOps = // user's event listener implementation
 ILanguageEventsPOATie eventServant = new ILanguageEventsPOATie(eventOps); 
 int handle = EventUtil.advise(iLang,eventID,eventServant);
 // eventOps can now received events from iLang
 EventUtil.unadvise(iLang,eventID,handle);
 // eventOps no longer can receive events from iLang
