Applications often require sending recurring or timed notifications. This can be done by creating a timer component that has a producer connected to a channel:
Code Block |
---|
|
public class SomeTimer implements Runnable {
@Producer(target="SomeChannel")
protected Channel channel;
public void run() {
Event event = ...
channel.publish(event);
}
}
|
Further, to limit timed events to a highly-available single source in a clustered zone (i.e. a clustered singleton), mark the implementation with @Domain orĀ @Scope("DOMAIN"):
Code Block |
---|
|
@Domain
public class SomeTimer implements Runnable {
@Producer(target="SomeChannel")
protected Channel channel;
public void run() {
Event event = ...
channel.publish(event);
}
}
