  Interface java.telephony.ProviderObserver
</h1>
<dl>
  <dt> public interface <b>ProviderObserver</b>
  <dt> extends <a href="java.lang.Object.html#_top_">Object</a>
</dl>
The ProviderObserver interface reports all state changes on the Provider
object as events. Applications instantiate an object which implements
this interface and uses the <EM>Provider.addObserver()</EM> method to begin
the delivery of events to this object. Applications may use the
<EM>Provider.removeObserver()</EM> method to discontinue the delivery of
events to an observer object. A list of observers on the Provider object can
be obtained via the <EM>Provider.getObservers()</EM> method
<p>
The ProviderObserver interface has one method:
<EM>providerChangedEvent()</EM>. This method takes a single argument, an
array of ProvEv objects. Applications iterate over this array for the
individual events. All Provider events must extend the
java.telephony.events.ProvEv interface.
<p>
The ProviderObserver reports a list of events because several state changes
may occur at once. To maintain the consistency between the state changes
in the call model and the events reported to the application, several
events may need to be delivered at once.
<p>
The ProviderObserver interface reports the following events. The hyper-links
below provide access to the specifications for these events.
