org.axonframework.messaging.eventhandling.annotation.MethodSequencingPolicyEventHandlerDefinition

All Implemented Interfaces:

HandlerEnhancerDefinition

public class MethodSequencingPolicyEventHandlerDefinition
extends Object
implements HandlerEnhancerDefinition

Definition of event handlers that are annotated with SequencingPolicy. These handlers are wrapped with a MethodSequencingPolicyEventHandlerDefinition.SequencingPolicyEventMessageHandlingMember that provides access to the configured sequencing policy.

The SequencingPolicy annotation can be applied either directly to the handler method or to the declaring class. When applied to the class, all handler methods in that class will inherit the sequencing policy. Method-level annotations take precedence over class-level annotations.
