Method Details

aroundSignal

public Behavior<I> aroundSignal(TypedActorContext<Object> ctx,
 Signal signal,
 BehaviorInterceptor.SignalTarget<I> target)

Description copied from class: BehaviorInterceptor

Override to intercept a signal sent to the running actor. Pass the signal on to the next behavior in the stack by passing it to target.apply.

Overrides:

aroundSignal in class BehaviorInterceptor<Object,I>

Returns:

The behavior for next message or signal

See Also:

• BehaviorSignalInterceptor

aroundStart

public Behavior<I> aroundStart(TypedActorContext<Object> ctx,
 BehaviorInterceptor.PreStartTarget<I> target)

Description copied from class: BehaviorInterceptor

Override to intercept actor startup. To trigger startup of the next behavior in the stack, call target.start().

Overrides:

aroundStart in class BehaviorInterceptor<Object,I>

Returns:

The returned behavior will be the "started" behavior of the actor used to accept the next message or signal.

dropped

public void dropped(TypedActorContext<?> ctx,
 Object signalOrMessage)

handleExceptionOnStart

protected abstract scala.PartialFunction<Throwable,Behavior<I>> handleExceptionOnStart(TypedActorContext<Object> ctx,
 BehaviorInterceptor.PreStartTarget<I> target)

handleReceiveException

protected abstract scala.PartialFunction<Throwable,Behavior<I>> handleReceiveException(TypedActorContext<Object> ctx,
 BehaviorInterceptor.ReceiveTarget<I> target)

handleSignalException

protected abstract scala.PartialFunction<Throwable,Behavior<I>> handleSignalException(TypedActorContext<Object> ctx,
 BehaviorInterceptor.SignalTarget<I> target)

isInstanceOfTheThrowableClass

protected boolean isInstanceOfTheThrowableClass(Throwable t)

isSame

public boolean isSame(BehaviorInterceptor<Object,Object> other)

Overrides:

isSame in class BehaviorInterceptor<Object,I>

Returns:

true if this behavior logically the same as another behavior interceptor and can therefore be eliminated (to avoid building infinitely growing stacks of behaviors)? Default implementation is based on instance equality. Override to provide use case specific logic.

log

public void log(TypedActorContext<?> ctx,
 Throwable t)

log

public void log(TypedActorContext<?> ctx,
 Throwable t,
 int errorCount)

toString

public String toString()

Overrides:

toString in class Object
