Method Detail

receive

public final Behavior<T> receive(TypedActorContext<T> ctx,
                                 T msg)
                          throws java.lang.Exception

Description copied from class: ExtensibleBehavior

Process an incoming message and return the next behavior.

The returned behavior can in addition to normal behaviors be one of the canned special objects:

* returning stopped will terminate this Behavior * returning same designates to reuse the current Behavior * returning unhandled keeps the same Behavior and signals that the message was not yet handled

Code calling this method should use Behavior$ canonicalize to replace the special objects with real Behaviors.

Specified by:

receive in class ExtensibleBehavior<T>

Throws:

java.lang.Exception

receiveMessage

public abstract Behavior<T> receiveMessage(T msg)
                                    throws java.lang.Exception

Process an incoming message and return the next behavior.

The returned behavior can in addition to normal behaviors be one of the canned special objects:

* returning stopped will terminate this Behavior * returning same designates to reuse the current Behavior * returning unhandled keeps the same Behavior and signals that the message was not yet handled

Throws:

java.lang.Exception

receiveSignal

public abstract Behavior<T> receiveSignal(Signal sig)
                                   throws java.lang.Exception

Process an incoming Signal and return the next behavior. This means that all lifecycle hooks, ReceiveTimeout, Terminated and Failed messages can initiate a behavior change.

The returned behavior can in addition to normal behaviors be one of the canned special objects:

* returning stopped will terminate this Behavior * returning same designates to reuse the current Behavior * returning unhandled keeps the same Behavior and signals that the message was not yet handled

Throws:

java.lang.Exception
