Sends a one-way asynchronous message.
Sends a one-way asynchronous message. E.g. fire-and-forget semantics.
If invoked from within an actor then the actor reference is implicitly passed on as the implicit 'sender' argument.
This actor 'sender' reference is then available in the receiving actor in the 'sender' member variable, if invoked from within an Actor. If not then no sender is available.
actor ! message
Comparison only takes address into account.

Forwards the message and passes the original sender actor as the sender.
Forwards the message and passes the original sender actor as the sender.
Works with '!' and '?'/'ask'.
Obtain ActorRef by possibly traversing the actor tree or looking it up at some provider-specific location.
Obtain ActorRef by possibly traversing the actor tree or looking it up at some provider-specific location. This method shall return the end result, i.e. not only the next step in the look-up; this will typically involve recursive invocation. A path element of ".." signifies the parent, a trailing "" element must be disregarded. If the requested path does not exist, return Nobody.
Obtain parent of this ref; used by getChild for ".
Obtain parent of this ref; used by getChild for ".." paths.
Is the actor shut down? The contract is that if this method returns true, then it will never be false again.
Is the actor shut down? The contract is that if this method returns true, then it will never be false again. But you cannot rely on that it is alive if it returns true, since this by nature is a racy method.
Returns the path for this actor (from this actor up to the root actor).

Sends the specified message to the sender, i.e. fire-and-forget semantics, including the sender reference if possible (not supported on all senders).

Actor-less logging implementation for synchronous logging to standard output. This logger is always attached first in order to be able to log failures during application start-up, even before normal logging is started. Its log level can be configured by setting
akka.stdout-loglevelinakka.conf.
