Method Detail

actorOf
ActorRef actorOf(Props props)
Create new actor as child of this context and give it an automatically generated name (currently similar to base64-encoded integer count, reversed and with “$” prepended, may change in the future).See
Props
for details on how to obtain aProps
object.- Throws:
ConfigurationException
- if deployment, dispatcher or mailbox configuration is wrongjava.lang.UnsupportedOperationException
- if invoked on an ActorSystem that uses a custom user guardian
-
actorOf
ActorRef actorOf(Props props, java.lang.String name)
Create new actor as child of this context with the given name, which must not be null, empty or start with “$”. If the given name is already in use, anInvalidActorNameException
is thrown.See
Props
for details on how to obtain aProps
object.- Throws:
InvalidActorNameException
- if the given name is invalid or already in useConfigurationException
- if deployment, dispatcher or mailbox configuration is wrongjava.lang.UnsupportedOperationException
- if invoked on an ActorSystem that uses a custom user guardian
-
actorSelection
ActorSelection actorSelection(java.lang.String path)
Construct anActorSelection
from the given path, which is parsed for wildcards (these are replaced by regular expressions internally). No attempt is made to verify the existence of any part of the supplied path, it is recommended to send a message and gather the replies in order to resolve the matching set of actors.
-
actorSelection
ActorSelection actorSelection(ActorPath path)
Construct anActorSelection
from the given path, which is parsed for wildcards (these are replaced by regular expressions internally). No attempt is made to verify the existence of any part of the supplied path, it is recommended to send a message and gather the replies in order to resolve the matching set of actors.

stop
void stop(ActorRef actor)
Stop the actor pointed to by the givenActorRef
; this is an asynchronous operation, i.e. involves a message send. If this method is applied to theself
reference from inside an Actor then that Actor is guaranteed to not process any further messages after this call; please note that the processing of the current message will continue, this method does not immediately terminate this actor.
