AkkaActorGateway

public AkkaActorGateway(akka.actor.ActorRef actor,
                        UUID leaderSessionID)

方法详细资料

ask

public scala.concurrent.Future<Object> ask(Object message,
                                           scala.concurrent.duration.FiniteDuration timeout)

Sends a message asynchronously and returns its response. The response to the message is returned as a future.

指定者:

ask 在接口中 ActorGateway

参数:

message - Message to be sent

timeout - Timeout until the Future is completed with an AskTimeoutException

返回:

Future which contains the response to the sent message

tell

public void tell(Object message)

Sends a message asynchronously without a result.

指定者:

tell 在接口中 ActorGateway

参数:

message - Message to be sent

tell

public void tell(Object message,
                 ActorGateway sender)

Sends a message asynchronously without a result with sender being the sender.

指定者:

tell 在接口中 ActorGateway

参数:

message - Message to be sent

sender - Sender of the message

forward

public void forward(Object message,
                    ActorGateway sender)

Forwards a message. For the receiver of this message it looks as if sender has sent the message.

指定者:

forward 在接口中 ActorGateway

参数:

message - Message to be sent

sender - Sender of the forwarded message

retry

public scala.concurrent.Future<Object> retry(Object message,
                                             int numberRetries,
                                             scala.concurrent.duration.FiniteDuration timeout,
                                             scala.concurrent.ExecutionContext executionContext)

Retries to send asynchronously a message up to numberRetries times. The response to this message is returned as a future. The message is re-sent if the number of retries is not yet exceeded and if an exception occurred while sending it.

指定者:

retry 在接口中 ActorGateway

参数:

message - Message to be sent

numberRetries - Number of times to retry sending the message

timeout - Timeout for each sending attempt

executionContext - ExecutionContext which is used to send the message multiple times

返回:

Future of the response to the sent message

path

public String path()

Returns the ActorPath of the remote instance.

指定者:

path 在接口中 ActorGateway

返回:

ActorPath of the remote instance.

actor

public akka.actor.ActorRef actor()

Returns ActorRef of the target actor

指定者:

actor 在接口中 ActorGateway

返回:

ActorRef of the target actor

leaderSessionID

public UUID leaderSessionID()

从接口复制的说明: ActorGateway

Returns the leaderSessionID associated with the remote actor or null.

指定者:

leaderSessionID 在接口中 ActorGateway

返回:

Leader session ID if its associated with this gateway, otherwise null

toString

public String toString()
