Package org.axonframework.eventsourcing.eventstore

Definitions and implementations of the Event store, the mechanism that can load event streams and append events to them.

See: Description

Interface Summary

Interface	Description
DomainEventData<T>	Interface describing the properties of serialized Domain Event Messages.
DomainEventStream	The DomainEventStream represents a stream of historical events published by an Aggregate.
EventData<T>	Interface describing the properties of serialized Event Messages.
EventStorageEngine	Provides a mechanism to append as well as retrieve events from an underlying storage like a database.
EventStore	Provides a mechanism to open streams from events in the the underlying event storage.
TrackedEventData<T>	Interface describing the properties of serialized Event Messages containing a TrackingToken.
TrackingEventStream	Describes a stream of TrackedEventMessages.
TrackingToken	Tag interface identifying a token that is used to identify the position of an event in an event stream.

Class Summary

Class	Description
AbstractDomainEventEntry<T>	Abstract base class of a serialized domain event.
AbstractEventEntry<T>	Abstract base class of a serialized event.
AbstractEventStorageEngine	Abstract event storage implementation that takes care of event serialization and upcasting.
AbstractEventStore	Abstract implementation of an EventStore that uses a EventStorageEngine to store and load events.
AbstractSequencedDomainEventEntry<T>	Abstract base class of a serialized domain event.
AbstractSnapshotEventEntry<T>	Abstract base class of a serialized snapshot event storing the state of an aggregate.
AbstractSnapshotEventEntry.PK	Primary key definition of the AbstractEventEntry class.
BatchingEventStorageEngine	Abstract EventStorageEngine implementation that fetches events in batches from the backing database.
ConcatenatingDomainEventStream	DomainEventStream implementation that concatenates multiple streams, taking into account that some sequence numbers may appear in more than one stream.
EmbeddedEventStore	Implementation of an EventStore that stores and fetches events using an EventStorageEngine.
EventUtils	Utility class for dealing with events and event streams.
GapAwareTrackingToken	Implementation of a TrackingToken that uses the global insertion sequence number of the event to determine tracking order and additionally stores a set of possible gaps that have been detected while tracking the event store.
GenericDomainEventEntry<T>	Generic implementation of a serialized domain event entry.
GenericTrackedDomainEventEntry<T>	Deprecated Use TrackedDomainEventData instead, as it uses composition (instead of inheritance)
GlobalSequenceTrackingToken	Tracking token based on the global sequence number of an event.
IteratorBackedDomainEventStream	DomainEventStream implementation that gets its messages from an Iterator.
SequenceEventStorageEngine	EventStorageEngine implementation that combines the streams of two event storage engines.
TrackedDomainEventData<T>	Specialization of the DomainEventData class that includes the Token representing the position of this event in a stream.
TrackingTokenParameterResolverFactory	Implementation of a ParameterResolverFactory that resolves the TrackingToken of an event message if that message is a TrackedEventMessage.

Exception Summary

Exception	Description
EventStoreException	Indicates that the given events stream could not be stored or read due to an underlying exception.
