public interface ExtensionId<T extends Extension>
Identifies an Extension Lookup of Extensions is done by object identity, so the Id must be the same wherever it's used, otherwise you'll get the same extension loaded multiple times.

  • Method Details

    • apply

      T apply(ActorSystem system)
      Returns an instance of the extension identified by this ExtensionId instance.

    • apply

      T apply(ClassicActorSystemProvider system)
      Returns an instance of the extension identified by this ExtensionId instance.

    • createExtension

      T createExtension(ExtendedActorSystem system)
      Is used by Pekko to instantiate the Extension identified by this ExtensionId, internal use only.

    • equals

      boolean equals(Object other)
      Overrides:
      equals in class Object

    • get

      T get(ActorSystem system)
      Returns an instance of the extension identified by this ExtensionId instance. Java API For extensions written in Scala that are to be used from Java also, this method should be overridden to get correct return type. 
      
 override def get(system: ActorSystem): TheExtension = super.get(system)

    • get

      T get(ClassicActorSystemProvider system)
      Returns an instance of the extension identified by this ExtensionId instance. Java API For extensions written in Scala that are to be used from Java also, this method should be overridden to get correct return type. 
      
 override def get(system: ClassicActorSystemProvider): TheExtension = super.get(system)

    • hashCode

      int hashCode()
      Overrides:
      hashCode in class Object
