Method Detail

Same

public <T> Behavior<T> Same()

Return this behavior from message processing in order to advise the system to reuse the previous behavior. This is provided in order to avoid the allocation overhead of recreating the current behavior where that is not necessary.

Returns:

(undocumented)

Unhandled

public <T> Behavior<T> Unhandled()

Return this behavior from message processing in order to advise the system to reuse the previous behavior, including the hint that the message has not been handled. This hint may be used by composite behaviors that delegate (partial) handling to other behaviors.

Returns:

(undocumented)

Stopped

public <T> Behavior<T> Stopped()

Return this behavior from message processing to signal that this actor shall terminate voluntarily. If this actor has created child actors then these will be stopped as part of the shutdown procedure. The PostStop signal that results from stopping this actor will NOT be passed to the current behavior, it will be effectively ignored.

Returns:

(undocumented)

Empty

public <T> Behavior<T> Empty()

This behavior does not handle any inputs, it is completely inert.

Returns:

(undocumented)

Ignore

public <T> Behavior<T> Ignore()

This behavior does not handle any inputs, it is completely inert.

Returns:

(undocumented)

SelfAware

public <T> Behavior<T> SelfAware(scala.Function1<ActorRef<T>,Behavior<T>> behavior)

A behavior decorator that extracts the self ActorRef while receiving the the first signal or message and uses that to construct the real behavior (which will then also receive that signal or message).

Example:

 SelfAware[MyCommand] { self =>
   Simple {
     case cmd =>
   }
 }
 

This can also be used together with implicitly sender-capturing message types:

 final case class OtherMsg(msg: String)(implicit val replyTo: ActorRef[Reply])

 SelfAware[MyCommand] { implicit self =>
   Simple {
     case cmd =>
       other ! OtherMsg("hello") // assuming Reply <: MyCommand
   }
 }
 

Parameters:

behavior - (undocumented)

Returns:

(undocumented)

ContextAware

public <T> Behavior<T> ContextAware(scala.Function1<ActorContext<T>,Behavior<T>> behavior)

A behavior decorator that extracts the ActorContext while receiving the the first signal or message and uses that to construct the real behavior (which will then also receive that signal or message).

Example:

 ContextAware[MyCommand] { ctx => Simple {
     case cmd =>
       ...
   }
 }
 

Parameters:

behavior - (undocumented)

Returns:

(undocumented)
