Method Summary

Methods

Modifier and Type	Method and Description
DomainEventStream	readEvents(String type, Object identifier, long firstSequenceNumber) Returns a Stream containing events for the aggregate identified by the given type and identifier, starting at the event with the given firstSequenceNumber (included).
DomainEventStream	readEvents(String type, Object identifier, long firstSequenceNumber, long lastSequenceNumber) Returns a Stream containing events for the aggregate identified by the given type and identifier, starting at the event with the given firstSequenceNumber (included) up to and including the event with given lastSequenceNumber.

Method Detail

readEvents

DomainEventStream readEvents(String type,
                           Object identifier,
                           long firstSequenceNumber)

Returns a Stream containing events for the aggregate identified by the given type and identifier, starting at the event with the given firstSequenceNumber (included).

The returned stream will not contain any snapshot events.

Parameters:

type - The type identifier of the aggregate

identifier - The identifier of the aggregate

firstSequenceNumber - The sequence number of the first event to find

Returns:

a Stream containing events for the given aggregate, starting at the given first sequence number

readEvents

DomainEventStream readEvents(String type,
                           Object identifier,
                           long firstSequenceNumber,
                           long lastSequenceNumber)

Returns a Stream containing events for the aggregate identified by the given type and identifier, starting at the event with the given firstSequenceNumber (included) up to and including the event with given lastSequenceNumber. If no event with given lastSequenceNumber exists, the returned stream will simply read until the end of the aggregate's events.

The returned stream will not contain any snapshot events.

Parameters:

type - The type identifier of the aggregate

identifier - The identifier of the aggregate

firstSequenceNumber - The sequence number of the first event to find

lastSequenceNumber - The sequence number of the last event in the stream

Returns:

a Stream containing events for the given aggregate, starting at the given first sequence number
