Method Summary

Methods

Modifier and Type	Method and Description

void	registerAggregateRoot(AbstractEventSourcedAggregateRoot aggregateRootToRegister) Register the aggregate root with this entity.

Method Detail

registerAggregateRoot

void registerAggregateRoot(AbstractEventSourcedAggregateRoot aggregateRootToRegister)

Register the aggregate root with this entity. The entity must use this aggregate root to apply Domain Events. The aggregate root is responsible for tracking all applied events.

A parent entity is responsible for invoking this method on its child entities prior to propagating events to it. Typically, this means all entities have their aggregate root set before any actions are taken on it.

Parameters:

aggregateRootToRegister - the root of the aggregate this entity is part of.

handleRecursively

void handleRecursively(DomainEventMessage event)

Report the given event for handling in the current instance (this), as well as all the entities referenced by this instance.

Parameters:

event - The event to handle
