1.  final class DeletedDurableState[A] extends DurableStateChange[A]
   A

   the type of the value

2.  sealed trait DurableStateChange[A] extends AnyRef

   The DurableStateStoreQuery stream elements for DurableStateStoreQuery.

   The DurableStateStoreQuery stream elements for DurableStateStoreQuery.

   The implementation can be a UpdatedDurableState or a DeletedDurableState.

   Not for user extension

3.  final class EventEnvelope extends Product4[Offset, String, Long, Any] with Serializable

   Event wrapper adding meta data for the events in the result stream of akka.persistence.query.scaladsl.EventsByTagQuery query, or similar queries.

   Event wrapper adding meta data for the events in the result stream of akka.persistence.query.scaladsl.EventsByTagQuery query, or similar queries.

   The timestamp is the time the event was stored, in milliseconds since midnight, January 1, 1970 UTC (same as System.currentTimeMillis).

4.  abstract class Offset extends AnyRef
5.  class PersistenceQuery extends PersistencePlugin[ReadJournal, ReadJournal, ReadJournalProvider] with Extension
6.  trait ReadJournalProvider extends AnyRef

   A query plugin must implement a class that implements this trait.

   A query plugin must implement a class that implements this trait. It provides the concrete implementations for the Java and Scala APIs.

   A read journal plugin must provide implementations for both akka.persistence.query.scaladsl.ReadJournal and akka.persistence.query.javadsl.ReadJournal. The plugin must implement both the scaladsl and the javadsl traits because the akka.stream.scaladsl.Source and akka.stream.javadsl.Source are different types and even though those types can easily be converted to each other it is most convenient for the end user to get access to the Java or Scala Source directly. One of the implementations can delegate to the other.

7.  final case class Sequence(value: Long) extends Offset with Ordered[Sequence] with Product with Serializable

   Corresponds to an ordered sequence number for the events.

   Corresponds to an ordered sequence number for the events. Note that the corresponding offset of each event is provided in the akka.persistence.query.EventEnvelope, which makes it possible to resume the stream at a later point from a given offset.

   The offset is exclusive, i.e. the event with the exact same sequence number will not be included in the returned stream. This means that you can use the offset that is returned in EventEnvelope as the offset parameter in a subsequent query.

8.  final case class TimeBasedUUID(value: UUID) extends Offset with Ordered[TimeBasedUUID] with Product with Serializable

   Corresponds to an ordered unique identifier of the events.

   Corresponds to an ordered unique identifier of the events. Note that the corresponding offset of each event is provided in the akka.persistence.query.EventEnvelope, which makes it possible to resume the stream at a later point from a given offset.

   The offset is exclusive, i.e. the event with the exact same sequence number will not be included in the returned stream. This means that you can use the offset that is returned in EventEnvelope as the offset parameter in a subsequent query.

9.  final class TimestampOffset extends Offset

   Timestamp based offset.

   Timestamp based offset. Since there can be several events for the same timestamp it keeps track of what sequence nrs for every persistence id that have been seen at this specific timestamp.

   The offset is exclusive, i.e. the event with the exact same sequence number will not be included in the returned stream. This means that you can use the offset that is returned in EventEnvelope as the offset parameter in a subsequent query.

10.  final class TimestampOffsetBySlice extends Offset

    Timestamp-based offset by slice.

    Timestamp-based offset by slice.

11.  final class UpdatedDurableState[A] extends DurableStateChange[A]
    A
