EventStoreTransaction	Interface describing the actions that can be taken on a transaction to source a model from the EventStore based on the resulting MessageStream.
GenericTaggedEventMessage<E extends EventMessage>	Implementation of the TaggedEventMessage allowing a generic EventMessage of type E.
GlobalIndexConsistencyMarker	ConsistencyMarker implementation that uses a single `long` to represent a position in an event stream.
GlobalIndexPosition	An immutable implementation of Position which represents positions with an index in the global event stream.
InterceptingEventStore	Decorator around the EventStore intercepting all events before they are appended or published with dispatch interceptors.
MetadataBasedTagResolver	Implementation of the TagResolver that resolves Tags based on a metadata key from an EventMessage.
MultiTagResolver	TagResolver that combines the results of multiple other tag resolvers.
PayloadBasedTagResolver<P>	Simple implementation of the TagResolver that is able to combine several lambdas to construct Tags from payloads of type P.
Position	Represents a position from which sourcing may start.
SourcingCondition	Interface describing the condition to source events from an Event Store.
StorageEngineBackedEventStore	An EventStore implementation which uses an EventStorageEngine as its storage solution.

TaggedEventMessage<E extends EventMessage>	A wrapper of an EventMessage and its Tags.
TagResolver	Functional interface towards resolving a Set of Tags for a given EventMessage.
TooManyTagsOnEventMessageException	Exception indicating that an Event could not be appended to the event store because it contains more tags than the storage engine can support.
