Camel stop() event
Hello,
I am wondering if there is a way, in a Camel route, to retrieve a kind of
"stop event" that might be sent from the context when asked for stopping?
Actually, one of my routes is processing a loop on multiple data and does a
long-running business task for each of these data. So when I try to stop the
Camel context, it uses the default shutdown strategy with the default
timeout but always finishes by killing my process.
So I am looking for a way to catch, within a route, a "bubbling" stop event
coming from the context that could be used in my business loop to check
after each processing if the context is asking for shutdown and cleanly stop
my tasks.
Is this possible?

Sorry for the mistake, I meant ' Nothing more interesting on "getContext()"
'.
I think I do not really understand. Where is this "isStopping()" method? In
2.9.0 it is not on CamelContext :

isStopping() should be a method on CamelContext itself.

Thank you for the answer.
The EventNotifier seems to match my needs, but I have none of the mentioned
methods on the context or on the status. I am in version 2.9.0 and on
getContext().getStatus() I only found, among others, "isStarting()",
"isStarted()", "isStoppable()" but not "isStopping()". Nothing more
interesting on "getStatus()". Is this in an other camel's version?

You can check the state of CamelContext as it has a getStatus method,
or use the isStopping() method.
And you can then check if its stopping.
There is also a isRunAllowed() method that the EIPs use themselves, so
sometimes it may be easier to check this method on the
CamelContext. As it will return false if Camel is stopping.
Alternative there is an event notifier in Camel, that send out events.
And you can then have a listener that receives the events from
http://camel.apache.org/maven/current/camel-core/apidocs/org/apache/camel/management/event/package-summary.html
There is a little example here about the events
