Type Members

1. trait ActorContext[T] extends typed.ActorContext[T]

   

   An Actor is given by the combination of a Behavior and a context in which this behavior is executed.

   An Actor is given by the combination of a Behavior and a context in which this behavior is executed. As per the Actor Model an Actor can perform the following actions when processing a message:

   • send a finite number of messages to other Actors it knows
   • create a finite number of Actors
   • designate the behavior for the next message

   In Akka the first capability is accessed by using the ! or tell method on an ActorRef, the second is provided by ActorContext#spawn and the third is implicit in the signature of Behavior in that the next behavior is always returned from the message processing logic.

   An ActorContext in addition provides access to the Actor’s own identity (“self”), the ActorSystem it is part of, methods for querying the list of child Actors it created, access to Terminated and timed message scheduling.

   Not for user extension.

2. abstract class MutableBehavior[T] extends ExtensibleBehavior[T]

   

   Mutable behavior can be implemented by extending this class and implement the abstract method MutableBehavior#onMessage and optionally override MutableBehavior#onSignal.

   Mutable behavior can be implemented by extending this class and implement the abstract method MutableBehavior#onMessage and optionally override MutableBehavior#onSignal.

   Instances of this behavior should be created via Behaviors#setup and if the ActorContext is needed it can be passed as a constructor parameter from the factory function.

3. trait StashBuffer[T] extends AnyRef

   

   A non thread safe mutable message buffer that can be used to buffer messages inside actors and then unstash them.

   A non thread safe mutable message buffer that can be used to buffer messages inside actors and then unstash them.

   The buffer can hold at most the given capacity number of messages.

   Not for user extension.

4. class StashOverflowException extends RuntimeException

   

   Is thrown when the size of the stash exceeds the capacity of the stash buffer.

5. trait TimerScheduler[T] extends AnyRef

   

   Support for scheduled self messages in an actor.

   Support for scheduled self messages in an actor. It is used with Behaviors.withTimers. Timers are bound to the lifecycle of the actor that owns it, and thus are cancelled automatically when it is restarted or stopped.

   TimerScheduler is not thread-safe, i.e. it must only be used within the actor that owns it.
