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
DomainEventStream	The DomainEventStream represents a stream of historical events published by an Aggregate.
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.

Class Summary

Class	Description
AbstractEventStorageEngine	Abstract EventStorageEngine implementation that takes care of event serialization and upcasting.
AbstractEventStorageEngine.Builder	Abstract Builder class to instantiate an AbstractEventStorageEngine.
AbstractEventStore	Abstract implementation of an EventStore that uses a EventStorageEngine to store and load events.
AbstractEventStore.Builder	Abstract Builder class to instantiate an AbstractEventStore.
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	AbstractEventStorageEngine implementation that fetches events in batches from the backing database.
BatchingEventStorageEngine.Builder	Abstract Builder class to instantiate a BatchingEventStorageEngine.
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.
EmbeddedEventStore.Builder	Builder class to instantiate an EmbeddedEventStore.
EqualRevisionPredicate	A predicate that matches against DomainEventData instances that have a revision 'equal' to the revision of the class is has serialized data for.
FilteringDomainEventStream	DomainEventStream implementation that filters a stream.
IteratorBackedDomainEventStream	DomainEventStream implementation that gets its messages from an Iterator.
SequenceEventStorageEngine	EventStorageEngine implementation that combines the streams of two event storage engines.

Exception Summary

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