Method Detail

getAddress

public java.lang.String getAddress()

Returns the Actor's address used for all "from" parameters.

Specified by:

getAddress in interface QuerySender

getActor

public Actor getActor()

getBroker

public Broker getBroker()

The underlying, low-level stream to the link

Specified by:

getBroker in interface ActorSender

Specified by:

getBroker in interface QuerySender

setBroker

public void setBroker(Broker broker)

getManagedBroker

protected ManagedBroker getManagedBroker()

message

public void message(java.lang.String to,
                    java.io.Serializable payload)

Sends a unidirectional message to an ActorHolder, addressed by the Actor's address.

Specified by:

message in interface ActorSender

Specified by:

message in interface QuerySender

Parameters:

to - the target actor's address

payload - the message payload

nextQueryId

public long nextQueryId()

Description copied from interface: ActorSender

Returns the next query identifier.

Specified by:

nextQueryId in interface ActorSender

getQueryManager

public QueryManager getQueryManager()

Specified by:

getQueryManager in interface QuerySender

query

public java.io.Serializable query(java.lang.String to,
                                  java.io.Serializable payload)

Sends a query information call (get) to an actor, blocking until the actor responds with a result or an error. The target actor of a queryGet acts as a service and the caller acts as a client. Because BAM Actors are symmetrical, all Actors can act as services and clients for different RPC calls. The target actor MUST send a queryResult or queryError to the client using the same id, because RPC clients rely on a response.

Specified by:

query in interface ActorSender

Specified by:

query in interface QuerySender

Parameters:

to - the target actor's address

payload - the query payload

query

public java.io.Serializable query(java.lang.String to,

                                  long timeout)

Sends a query information call (get) to an actor, blocking until the actor responds with a result or an error. The target actor of a queryGet acts as a service and the caller acts as a client. Because BAM Actors are symmetrical, all Actors can act as services and clients for different RPC calls. The target actor MUST send a queryResult or queryError to the client using the same id, because RPC clients rely on a response.
