package org.axonframework.eventhandling.annotation;

Annotation that marks a class as an Asynchronous EventListener. Postprocessors will detect this bean and wrap it with a suitable AsynchronousEventHandlerWrapper. This type-level annotation allows the definition of the concurrency policy for this EventListener.

This annotation allows the configuration of any arbitrary class, as long as it implements the org.axonframework.eventhandling.SequencingPolicy interface. It also needs to have (at least) a no-arg constructor.
