  - - akka.actor.typed.internal.PoisonPillInterceptor<M>

```
public final class PoisonPillInterceptor<M>
extends BehaviorSignalInterceptor<M>
```
INTERNAL API
Returns Behaviors.stopped for PoisonPill signals unless it has been handled by the target Behavior. Used by Cluster Sharding to automatically stop entities without defining a stop message in the application protocol. Persistent actors handle PoisonPill and run side effects after persist and process stashed messages before stopping.

public Behavior<M> aroundSignal(TypedActorContext<M> ctx,
                                Signal signal,
                                BehaviorInterceptor.SignalTarget<M> target)
```
    Description copied from class: BehaviorSignalInterceptor
    
    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.
    
    Specified by:
    
    aroundSignal in class BehaviorSignalInterceptor<M>
    
    Returns:
    
    The behavior for next message or signal

```
public boolean isSame(BehaviorInterceptor<java.lang.Object,java.lang.Object> other)
```
    Overrides:
    
    isSame in class BehaviorInterceptor<M,M>
    
    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.
