Interface Summary

Interface	Description
WithState<ID,EVENT_TYPE,AGGREGATE_TYPE extends AggregateRoot<ID,EVENT_TYPE,AGGREGATE_TYPE>,AGGREGATE_STATE extends AggregateState<ID,EVENT_TYPE,AGGREGATE_TYPE>>	Marker interface that indicates that all state and all EventHandler annotated methods will be hosted with the AggregateState object.

Class Summary

Class	Description
AggregateRoot<ID,EVENT_TYPE,AGGREGATE_TYPE extends AggregateRoot<ID,EVENT_TYPE,AGGREGATE_TYPE>>	A modern opinionated interpretation of the classic AggregateRoot design, where the Event's are mutable. The modern interpretation doesn't specify any requirement on the design of the Events, they can be Java 17+ records or simple POJO's. Note: The AggregateRoot works best in combination with the StatefulAggregateRepository that's configured to use the StatefulAggregateInstanceFactory.reflectionBasedAggregateRootFactory(), because the AggregateRoot needs to be provided its aggregated id through the AggregateRoot(Object) constructor! The modern AggregateRoot supports keeping the state projection and EventHandler annotated methods within the AggregateRoot instance or within an AggregateState instance. If you wish to keep the state projection and EventHandler annotated methods within an AggregateState instance, then you only need to implement the WithState interface:
AggregateState<ID,EVENT_TYPE,AGGREGATE_TYPE extends AggregateRoot<ID,EVENT_TYPE,AGGREGATE_TYPE>>	Aggregate state object associated with a given AggregateRoot instance (see AggregateState.getAggregate()) Example:
