[Asterisk-java-users] AsteriskManager

[Alex M. <al...@go...>]

Is there any way to get a concrete implementation of AsteriskManager
currently (preferably that uses a pre-existing ManagerConnection for
connection information)?

What I need to do is get a list of channels and map them to my list of
Employee objects so that I can add channel event listeners and have each
Employee be self-updating rather than monitoring the ManagerConnection
for events that relate to a particular user. Is this possible or will it
be possible at some point?

[Asterisk-java-users] UserEvents

[Chris H. <ch...@as...>]

I'm currently working with an older version of Asterisk Java (plan on 
updating soon but I don't have time for regression test). I have a need for 
a user defined event but the UserEvent class was not included in the 
version I was working with.  I pull the user event class from the latest cvs 
and added it.  Created my own user event

public class UserEventASGHold extends UserEvent
{
  private String callerId;
   public UserEventASGHold(Object source)
   {
     super(source);
   }

   public String getCallerId()
   {
     return callerId;
   }

   public void setCallerId(String callerId)
   {
     this.callerId = callerId;
   }
 }

I call the event via:
exten => _0262,10,UserEvent(ASGHold|callerId: ${CALLERIDNUM})

Now I get the warning:

WARNING: No event class registered for event type 'usereventasghold', 
attributes: {callerid=0262, uniqueid=1110900347.498, event=UserEventASGHold, 
channel=Zap/38-1}

How do I register the event?  Is this because I'm using a old version of the 
core code?

Thanks,
Chris

I was mainly working on the FastAGI implementation for the last time, so
it "shouldn't" break your Manager API stuff.

Your class must be named ASGHoldEvent just the name of the event you
will send with the appendix Event.

The newer code base includes a method called
registerUserEventClass(Class userEventClass) in the ManagerConnection
interface so you would just call

managerConnection.registerUserEventClass(ASGHoldEvent.class);

If you are unable to upgrade right now and don't mind to change
Asterisk-java's internal code you can also add your event to the
EventBuilder (this is either net.sf.asterisk.manager.EventBuilder or in
newer versions net.sf.asterisk.manager.impl.EventBuilderImpl).
There is a private method called registerBuiltinEventClasses() where you
can add a

registerEventClass(ASGHoldEvent.class);

Hope that helps

I just had a look at the asterisk sources to verify that and indeed
asterisk prefixes user events with UserEvent.
So for now your class should be named UserEventASGHoldEvent - which
really sucks.

ok. i just had a look at my sources to verify whats going on there :)

if the class name ends with "event" (ignoring case) that part is
stripped of, if not it is takes the full class name.

I added support for user events to latest cvs so if your event extends
UserEvent and does not start with "userevent" that string is prepended.
so you can name your class ASGHold, ASGHoldEvent, UserEventASGHold or
even UserEventASGHoldEvent with latest CVS.
I would prefer ASGHoldEvent for a uniform naming schema.

Speed has not yet been optimized. I think the biggest "problem" is
currently that the ManagerEventHandlers are called within the same
thread as the events are received. So if you do a lot of processing in
your handleEvent() methods that will block any other events from being
received and (if you registered more than one EventHandler) other
EventHandlers from being called timely.
There is no easy solution to this because events must be dispatched in
the right order. One possible solution is to use a separate Thread for
each registered EventHandler.
Do you encounter speed problems right now? Do you use multiple
EventHandlers?

Yes that might improve speed but if you check for the events you are
interested in early in the handleEvent() method and return fast if not
interested handling these additional events should not be much of an
issue.
Note that not registering events received from Asterisk will fill your
logs with warnings about that.
For the 0.1 release i plan to add an=20
addEventHandler(ManagerEventHandler eventHandler, ManagerEventFilter
filer)
method to the ManagerConnection so you can indicate which events you are
interested in and Asterisk-java will not bother you with the irrelevant
ones.
