Annotation Interface Subscribe
Annotation for single-argument (void) methods that indicates that the method is a listener.
The parameter type is to be used to filter events.
Annotated methods may be invoked synchronously or asynchronously, depending on which eventbus they are delivered, but in any case must refrain from expensive operations since that will block the entire event delivery mechanism, and also the event raising process in case of synchronous events.
This annotation is a fork of the guava eventbus annotation. This was necessary since we do not want to push the guava library (see http://code.google.com/p/guava-libraries/) onto the shared class path.
