Method Summary

Modifier and Type	Method and Description
void	error(AmpActorRef to, AmpActorRef from, AmpEncoder encoder, AmpError error) Sends a message error to an ActorHolder, addressed by the Actor's address.

send

public void send(AmpActorRef to,
                 AmpActorRef from,
                 AmpEncoder encoder,
                 java.lang.String methodName,
                 java.lang.Object... args)

Description copied from interface: AmpStream

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

Specified by:

send in interface AmpStream

Parameters:

to - the target actor's address

from - the source actor's address

error

public void error(AmpActorRef to,
                  AmpActorRef from,
                  AmpEncoder encoder,
                  AmpError error)

Description copied from interface: AmpStream

Sends a message error to an ActorHolder, addressed by the Actor's address. Actor protocols may choose to send error messages if a message fails for some reason. In general, Actors should not rely on the delivery of error messages. If an error return is required, use an RPC query instead.

Specified by:

error in interface AmpStream

Parameters:

to - the target actor's address

from - the source actor's address

error - the message error

query

public void query(long id,
                  AmpActorRef to,
                  AmpActorRef from,
                  AmpEncoder encoder,
                  java.lang.String methodName,
                  java.lang.Object... args)

Description copied from interface: AmpStream

Sends a query/RPCinformation call The receiver of a query 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 stream 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 AmpStream

Parameters:

id - the query identifier used to match requests with responses

to - the service actor's address

from - the client actor's address

queryResult

public void queryResult(long id,
                        AmpActorRef to,
                        AmpActorRef from,
                        AmpEncoder encoder,
                        java.lang.Object result)

Description copied from interface: AmpStream

Sends a query response for a query

Specified by:

queryResult in interface AmpStream

Parameters:

id - the query identifier used to match requests with responses

to - the client actor's address

from - the service actor's address

queryError

public void queryError(long id,
                       AmpActorRef to,
                       AmpActorRef from,
                       AmpEncoder encoder,
                       AmpError error)

Description copied from interface: AmpStream

Sends a query error from a failed query.

Specified by:

queryError in interface AmpStream

Parameters:

id - the query identifier used to match requests with responses

to - the client actor's address

from - the service actor's address

error - additional error information

getMethod

public AmpMethodRef getMethod(java.lang.String methodName,
                              AmpEncoder encoder)

Specified by:

getMethod in interface AmpActor
