Abstract Value Members
- abstract def readAllMessages(from: LogPosition, direction: Direction, maxCount: Long, resolveLinkTos: Boolean): Stream[F, AllMessage]
Read AllMessage messages from the global stream, sec.StreamId.All.
Read AllMessage messages from the global stream, sec.StreamId.All.
- from
log position to read from.
- direction
whether to read forwards or backwards.
- maxCount
limits maximum events returned.
- resolveLinkTos
whether to resolve EventType.LinkTo events automatically.
- returns
a Stream that emits AllMessage values.
- abstract def readStreamMessages(streamId: StreamId, from: StreamPosition, direction: Direction, maxCount: Long, resolveLinkTos: Boolean): Stream[F, StreamMessage]
Read StreamMessage messages from an individual stream.
Read StreamMessage messages from an individual stream.
- streamId
the id of the stream to subscribe to.
- from
stream position to read from.
- direction
whether to read forwards or backwards.
- maxCount
limits maximum events returned.
- resolveLinkTos
whether to resolve EventType.LinkTo events automatically.
- returns
a Stream that emits StreamMessage values.
