Interface Coordination</H2>
<HR>
<DL>
<DT><PRE>public interface <B>Coordination</B></DL>
</PRE>
<P>
A Coordination object is used to coordinate a number of independent
Participants.
<p>
Once a Coordination is <A HREF="../../../../org/osgi/service/coordinator/Coordinator.html#create(java.lang.String, long)"><CODE>created</CODE></A>, it
can be used to add <A HREF="../../../../org/osgi/service/coordinator/Participant.html" title="interface in org.osgi.service.coordinator"><CODE>Participant</CODE></A> objects. When the Coordination is
ended, the participants are <A HREF="../../../../org/osgi/service/coordinator/Participant.html#ended(org.osgi.service.coordinator.Coordination)"><CODE>notified</CODE></A>.
A Coordination can also fail for various reasons. When this occurs, the
participants are <A HREF="../../../../org/osgi/service/coordinator/Participant.html#failed(org.osgi.service.coordinator.Coordination)"><CODE>notified</CODE></A> of the
failure.
<p>
A Coordination must be in one of two states, either ACTIVE or TERMINATED. The
transition between ACTIVE and TERMINATED must be atomic, ensuring that a
Participant can be guaranteed of either receiving an exception when adding
itself to a Coordination or of receiving notification the Coordination has
terminated.
<p>
A Coordination object is thread safe and can be passed as a parameter to
other parties regardless of the threads these parties use.
<p>
The following example code shows how a Coordination should be used.
<pre>
void foo() {
Coordination c = coordinator.create("work", 0);
try {
doWork(c);
}
catch (Exception e) {
c.fail(e);
}
finally {
c.end();
}
}

If this Coordination has been <A HREF="../../../../org/osgi/service/coordinator/Coordination.html#push()"><CODE>pushed</CODE></A> on the thread local
Coordination stack of another thread, this method does nothing except
throw a CoordinationException of type
<A HREF="../../../../org/osgi/service/coordinator/CoordinationException.html#WRONG_THREAD"><CODE>CoordinationException.WRONG_THREAD</CODE></A>.
<p>
If this Coordination has been <A HREF="../../../../org/osgi/service/coordinator/Coordination.html#push()"><CODE>pushed</CODE></A> on the thread local
Coordination stack of this thread but is not the
<A HREF="../../../../org/osgi/service/coordinator/Coordinator.html#peek()"><CODE>current Coordination</CODE></A>, then the Coordinations
on the thread local Coordination stack above this Coordination must be
terminated and removed from the thread local Coordination stack before
this Coordination is terminated. Each of these Coordinations, starting
with the current Coordination, will be <A HREF="../../../../org/osgi/service/coordinator/Coordination.html#end()"><CODE>terminated normally</CODE></A>
. If the termination throws a <A HREF="../../../../org/osgi/service/coordinator/CoordinationException.html" title="class in org.osgi.service.coordinator"><CODE>CoordinationException</CODE></A>, then the
next Coordination on the thread local Coordination stack will be
<A HREF="../../../../org/osgi/service/coordinator/Coordination.html#fail(java.lang.Throwable)"><CODE>terminated as a failure</CODE></A> with a failure cause of
the thrown CoordinationException. At the end of this process, this
Coordination will be the current Coordination and will have been
terminated as a failure if any of the terminated Coordinations threw a
CoordinationException
<p>

<p>
If this Coordination is already terminated, a CoordinationException is
thrown. If this Coordination was terminated as a failure, the

CoordinationException.

Otherwise, this Coordination is terminated normally and then all

finalize any work associated with this Coordination. The successful
return of this method indicates that the Coordination has terminated
normally and all registered Participants have been notified of the normal
termination.
<p>
It is possible that one of the Participants throws an exception during
notification. If this happens, this Coordination is considered to have
partially failed and this method must throw a CoordinationException of
type <A HREF="../../../../org/osgi/service/coordinator/CoordinationException.html#PARTIALLY_ENDED"><CODE>CoordinationException.PARTIALLY_ENDED</CODE></A> after all the

<DL>
<DD>Register a Participant with this Coordination.
<p>
Once a Participant is registered with this Coordination, it is guaranteed
to receive a notification for either
<A HREF="../../../../org/osgi/service/coordinator/Participant.html#ended(org.osgi.service.coordinator.Coordination)"><CODE>normal</CODE></A> or
<A HREF="../../../../org/osgi/service/coordinator/Participant.html#failed(org.osgi.service.coordinator.Coordination)"><CODE>failure</CODE></A> termination when this
Coordination is terminated.
<p>
Participants are registered using their object identity. Once a
Participant is registered with this Coordination, subsequent attempts to
register the Participant again with this Coordination are ignored and the
Participant is only notified once when this Coordination is terminated.
<p>
A Participant can only be registered with a single active Coordination at
a time. If a Participant is already registered with an active
Coordination, attempts to register the Participation with another active
Coordination will block until the Coordination the Participant is
registered with terminates. Notice that in edge cases the notification to
the Participant that this Coordination has terminated can happen before
this method returns.
<p>
Attempting to register a Participant with a <A HREF="../../../../org/osgi/service/coordinator/Coordination.html#isTerminated()"><CODE>terminated</CODE></A> Coordination will result in a CoordinationException being
thrown.
<p>
The ordering of notifying Participants must follow the order in which the
Participants were registered.
