Method Detail

buf

public scala.collection.immutable.Vector<EventEnvelope> buf()

Specified by:

buf in interface DeliveryBuffer<EventEnvelope>

context

public ActorContext context()

Description copied from interface: Actor

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!

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

Specified by:

context in interface Actor

Returns:

(undocumented)

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

Returns:

(undocumented)

tag

public java.lang.String tag()

fromOffset

public long fromOffset()

maxBufSize

public int maxBufSize()

writeJournalPluginId

public java.lang.String writeJournalPluginId()

journal

public ActorRef journal()

currOffset

public long currOffset()

toOffset

public abstract long toOffset()

receive

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

Description copied from interface: Actor

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

Specified by:

receive in interface Actor

Returns:

(undocumented)

init

public scala.PartialFunction<java.lang.Object,scala.runtime.BoxedUnit> init()

receiveInitialRequest

public abstract void receiveInitialRequest()

idle

replay

public void replay()

replaying

public scala.PartialFunction<java.lang.Object,scala.runtime.BoxedUnit> replaying(int limit)
