Interface Summary

Interface	Description
Aggregate<T>	Interface that describes an aggregate.
ApplyMore	Interface that describes a mechanism that enables the application of an additional event after another event is applied.
ForwardingMode<T extends Message<?>>	Interface describing the required functionality to forward a message.
Repository<T>	The repository provides an abstraction of the storage of aggregates.
RepositoryProvider	Provides a repository for given aggregate type.

Class Summary

Class	Description
AbstractRepository<T,A extends Aggregate<T>>	Abstract implementation of the Repository that takes care of the dispatching of events when an aggregate is persisted.
AggregateLifecycle	Abstract base class of a component that models an aggregate's life cycle.
AggregateScopeDescriptor	Describes the scope of an Aggregate by means of its type and identifier.
ForwardMatchingInstances<T extends Message<?>>	Only forward messages of type T if the routing key of the message matches that of the entity.
ForwardNone<T extends Message<?>>	Forward no messages T regardless of their set up.
ForwardToAll<T extends Message<?>>	Forward all messages T regardless of their set up.
GenericJpaRepository<T>	Generic repository implementation that stores JPA annotated aggregates.
LockAwareAggregate<AR,A extends Aggregate<AR>>	Aggregate implementation that provides access to the lock held by the aggregate while a command is handled.
LockingRepository<T,A extends Aggregate<T>>	Implementation of the Repository interface that takes provides a locking mechanism to prevent concurrent modifications of persisted aggregates.

Exception Summary

Exception	Description
AggregateEntityNotFoundException	Exception indicating that the an entity for an aggregate could not be found.
AggregateInvocationException	Exception thrown when an invocation on a method of an aggregate gives rise to an exception.
AggregateNotFoundException	Exception indicating that the an aggregate could not be found in the repository.
AggregateRolledBackException	Exception indicating that an aggregate has been part of a Unit of Work that was rolled back and that the validity of its state cannot be guaranteed.
ConcurrencyException	Exception indicating that concurrent access to a repository was detected.
ConflictingAggregateVersionException	Exception indicating that the (actual) version of a loaded aggregate did not match the given expected version number.
ConflictingModificationException	Root of a hierarchy of exceptions indicating the detection of conflicting concurrent modifications.

Annotation Types Summary

Annotation Type	Description
AggregateIdentifier	Field annotation that identifies the field containing the identifier of the Aggregate.
AggregateMember	Marker annotation for a field that references one or more Entities capable of handling Commands or Events.
AggregateRoot	Annotation placed on types that should be treated as the root of an aggregate.
AggregateVersion	Field annotation that indicates the field contains the value that represents the version of the Aggregate, used for optimistic locking, as well as state validation for commands.
CommandHandlerInterceptor	Annotation used to mark methods on Aggregate members which can intercept commands.
EntityId	Field annotation that marks the field containing the identifier of an Entity.
