      • apply

        public akka.persistence.CompositeMetadata apply​(scala.collection.immutable.Seq<java.lang.Object> entries)
        INTERNAL API: Metadata entries keyed by metadata class.

        For backwards compatibility of for example EventEnvelope.eventMetadata the entries is a Seq with the metadata that was added last (ReplicatedEventMetaData) at the head of the Seq. Otherwise it could have been a Map[Class, Any].
