PersistentEntityRegistry

trait PersistentEntityRegistry extends AnyRef

At system startup all PersistentEntity classes must be registered here with PersistentEntityRegistry#register.

Later, com.lightbend.lagom.scaladsl.persistence.PersistentEntityRef can be retrieved with PersistentEntityRegistry#refFor. Commands are sent to a com.lightbend.lagom.scaladsl.persistence.PersistentEntity using a PersistentEntityRef.

Abstract Value Members

  1. abstract def eventStream[Event <: AggregateEvent[Event]](aggregateTag: AggregateEventTag[Event], fromOffset: Offset): Source[EventStreamElement[Event], NotUsed]

    A stream of the persistent events that have the given aggregateTag, e.g.

    A stream of the persistent events that have the given aggregateTag, e.g. all persistent events of all Order entities.

    The type of the offset is journal dependent, some journals use time-based UUID offsets, while others use sequence numbers. The passed in fromOffset must either be akka.persistence.query.NoOffset, or an offset that has previously been produced by this journal.

    The stream will begin with events starting after fromOffset. To resume an event stream, store the Offset corresponding to the most recently processed Event, and pass that back as the value for fromOffset to start the stream from events following that one.

    Exceptions thrown

    IllegalArgumentException If the fromOffset type is not supported by this journal.

  2. abstract def refFor[P <: PersistentEntity](entityId: String)(implicit arg0: ClassTag[P]): PersistentEntityRef[refFor.P.Command]

    Retrieve a com.lightbend.lagom.scaladsl.persistence.PersistentEntityRef for a given com.lightbend.lagom.scaladsl.persistence.PersistentEntity class and identifier.

    Retrieve a com.lightbend.lagom.scaladsl.persistence.PersistentEntityRef for a given com.lightbend.lagom.scaladsl.persistence.PersistentEntity class and identifier. Commands are sent to a PersistentEntity using a PersistentEntityRef.

  3. abstract def register(entityFactory: ⇒ PersistentEntity): Unit

    At system startup all com.lightbend.lagom.scaladsl.persistence.PersistentEntity classes must be registered with this method.

    At system startup all com.lightbend.lagom.scaladsl.persistence.PersistentEntity classes must be registered with this method.

    The entityFactory will be called when a new entity instance is to be created. That will happen in another thread, so the entityFactory must be thread-safe, e.g. not close over shared mutable state that is not thread-safe.
