java.lang.Object akka.actor.UntypedActor akka.actor.UntypedActorWithUnrestrictedStash
public abstract class UntypedActorWithUnrestrictedStash
Actor base class with Stash
that does not enforce any mailbox type. The mailbox of the actor has to be configured
manually. See UntypedActorWithStash
for details on how Stash
works.

Method Detail |

public ActorContext context()
Context of the actor that uses this stash.
public ActorRef self()
Self reference of the actor that uses this stash.
public scala.collection.immutable.Vector<Envelope> theStash()
public akka.actor.ActorCell actorCell()
public int capacity()
public DequeBasedMessageQueueSemantics mailbox()
The actor's deque-based message queue.
mailbox.queue
is the underlying Deque
.
public void stash()
StashOverflowException
- in case of a stash capacity violation
java.lang.IllegalStateException
- if the same message is stashed more than oncepublic void prepend(scala.collection.immutable.Seq<Envelope> others)
others
to this stash. This method is optimized for a large stash and
small others
.
public void unstash()
Messages from the stash are enqueued to the mailbox until the capacity of the
mailbox (if any) has been reached. In case a bounded mailbox overflows, a
MessageQueueAppendFailedException
is thrown.
The unstashed message is guaranteed to be removed from the stash regardless
if the unstash()
call successfully returns or throws an exception.
public void unstashAll()
Messages from the stash are enqueued to the mailbox until the capacity of the
mailbox (if any) has been reached. In case a bounded mailbox overflows, a
MessageQueueAppendFailedException
is thrown.
The stash is guaranteed to be empty after calling unstashAll()
.
public void unstashAll(scala.Function1<java.lang.Object,java.lang.Object> filterPredicate)
Prepends selected messages in the stash, applying filterPredicate
, to the
mailbox, and then clears the stash.
Messages from the stash are enqueued to the mailbox until the capacity of the
mailbox (if any) has been reached. In case a bounded mailbox overflows, a
MessageQueueAppendFailedException
is thrown.
The stash is guaranteed to be empty after calling unstashAll(Any => Boolean)
.
filterPredicate
- only stashed messages selected by this predicate are
prepended to the mailbox.public scala.collection.immutable.Vector<Envelope> clearStash()
Clears the stash and and returns all envelopes that have not been unstashed.
public void enqueueFirst(Envelope envelope)
envelope
at the first position in the mailbox. If the message contained in
the envelope is a Terminated
message, it will be ensured that it can be re-received
by the actor.
