org.axonframework.modelling.saga.EndSagaMessageHandlerDefinition.EndSageMessageHandlingMember<T>

Type Parameters:

T - the entity type wrapped by this MessageHandlingMember

All Implemented Interfaces:

MessageHandlingMember<T>

Enclosing class:

EndSagaMessageHandlerDefinition

public static class EndSagaMessageHandlerDefinition.EndSageMessageHandlingMember<T>
extends WrappedMessageHandlingMember<T>

A WrappedMessageHandlingMember implementation dedicated towards MessageHandlingMembers annotated with EndSaga. After invocation of the handle(Message, ProcessingContext, Object) method, the saga is ended through the SagaLifecycle.end() method, whether the handler succeeded or failed: Axon Framework 4 called SagaLifecycle.end() in a finally block, so a throwing @EndSaga handler ended its saga all the same.
