API changes in Akka Typed

We have done some additional API changes to Akka Typed since 2.5.11. Sorry for the inconvenience but it should be a straight forward find-replace migration.

Renames:

  • Behaviors.immutable -> Behaviors.receive
  • Behaviors.immutablePartial -> Behaviors.receivePartial
  • Behaviors.onSignal -> Behaviors.receiveSignal
  • Behaviors.immutable … onSignal -> Behaviors.receive … receiveSignal
  • Behaviors.mutable -> Behaviors.setup
  • Behaviors.MutableBehavior -> MutableBehavior (top level class)
  • ExtensibleBehavior.receiveMessage -> ExtensibleBehavior.receive

New:

  • Behaviors.receiveMessage (similar to Behaviors.receive, but handling only the message, no context)
  • Behaviors.receiveMessagePartial

See issue #24683
