Applications instantiate an object which implementsthis interface and uses the <EM>Address.addObserver()</EM> method to beginthe delivery of events to this object. Applications may use the<EM>Address.removeObserver()</EM> method to discontinue the delivery ofevents to an observer object. A list of observers on the Address object canbe obtained via the <EM>Address.getObservers()</EM> method. Events will bedelivered to the AddressObserver interface only if the Provider is in theProvider.IN_SERVICE state.<p>The AddressObserver interface has one method: <EM>addressChangedEvent()</EM>.This method takes a single argument, an array of AddrEv objects. Applicationsiterate over this array for the individual events. All Address events mustextend the java.telephony.events.AddrEv interface.<p>The AddressObserver reports a list of events because several state changesmay occur at once. To maintain the consistency between the state changesin the call model and the events reported to the application, severalevents may need to be delivered at once.<p>The AddressObserver interface reports the following events. The hyper-linksbelow provide access to the specifications for these events.<p><dl> <dt> <b>See Also:</b> <dd> <a href="java.telephony.events.AddrEv.html#_top_">AddrEv</a></dl><hr><a name="index"></a><h2> <img src="images/method-index.gif" width=207 height=38 alt="Method Index"></h2><dl> <dt> <img src="images/red-ball-small.gif" width=6 height=6 alt=" o "> <a href="#addressChangedEvent(java.telephony.events.AddrEv[])"><b>addressChangedEvent</b></a>(AddrEv[]) <dd> Reports all events on the AddressObserver interface.</dl><a name="methods"></a><h2> <img src="images/methods.gif" width=151 height=38 alt="Methods"></h2><a name="addressChangedEvent(java.telephony.events.AddrEv[])"><img src="images/red-ball.gif" width=12 height=12 alt=" o "></a><a name="addressChangedEvent"><b>addressChangedEvent</b></a><pre> public abstract void addressChangedEvent(<a href="java.telephony.events.AddrEv.html#_top_">AddrEv</a> eventList[])</pre><dl> <dd> Reports all events on the AddressObserver interface.
