context

public ActorContext context()

Description copied from interface: Actor

Scala API: Stores the context for this actor, including self, and sender. It is implicit to support operations such as forward.

WARNING: Only valid within the Actor itself, so do not close over it and publish it to other threads!

pekko.actor.ActorContext is the Scala API. getContext returns a pekko.actor.AbstractActor.ActorContext, which is the Java API of the actor context.

Specified by:

context in interface Actor

self

public final ActorRef self()

Description copied from interface: Actor

The 'self' field holds the ActorRef for this actor.

Can be used to send messages to itself:

 self ! message
 

Specified by:

self in interface Actor

org$apache$pekko$actor$Actor$_setter_$context_$eq

protected void org$apache$pekko$actor$Actor$_setter_$context_$eq(ActorContext x$1)

Description copied from interface: Actor

Scala API: Stores the context for this actor, including self, and sender. It is implicit to support operations such as forward.

WARNING: Only valid within the Actor itself, so do not close over it and publish it to other threads!

pekko.actor.ActorContext is the Scala API. getContext returns a pekko.actor.AbstractActor.ActorContext, which is the Java API of the actor context.

Specified by:

org$apache$pekko$actor$Actor$_setter_$context_$eq in interface Actor

org$apache$pekko$actor$Actor$_setter_$self_$eq

protected final void org$apache$pekko$actor$Actor$_setter_$self_$eq(ActorRef x$1)

Description copied from interface: Actor

The 'self' field holds the ActorRef for this actor.

Can be used to send messages to itself:

 self ! message
 

Specified by:

org$apache$pekko$actor$Actor$_setter_$self_$eq in interface Actor

serialization

public Serialization serialization()

serializer

public SerializerWithStringManifest serializer()

manifest

public String manifest()

writeBehindInterval

public scala.concurrent.duration.FiniteDuration writeBehindInterval()

dir

pending

postRestart

public void postRestart(Throwable reason)

Description copied from interface: Actor

User overridable callback: By default it calls preStart().

Specified by:

postRestart in interface Actor

Parameters:

reason - the Throwable that caused the restart to happen

Is called right AFTER restart on the newly created Actor to allow reinitialization after an Actor crash.

postStop

public void postStop()

Description copied from interface: Actor

User overridable callback.

Is called asynchronously after 'actor.stop()' is invoked. Empty default implementation.

Specified by:

postStop in interface Actor

receive

public scala.PartialFunction<Object,scala.runtime.BoxedUnit> receive()

Description copied from interface: Actor

Scala API: This defines the initial actor behavior, it must return a partial function with the actor logic.

Specified by:

receive in interface Actor

init
