ActorContextImpl

public ActorContextImpl(java.lang.String address,
                        AmpActor actorStream,
                        AmpMailboxFactory mailboxFactory)

Method Detail

getAddress

public java.lang.String getAddress()

Specified by:

getAddress in class AmpActorContext

getMailbox

public AmpMailbox getMailbox()

Specified by:

getMailbox in class AmpActorContext

getActorRef

public AmpActorRef getActorRef()

Specified by:

getActorRef in class AmpActorContext

getStream

public AmpStream getStream()

Specified by:

getStream in class AmpActorContext

getMethod

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

Specified by:

getMethod in interface AmpActor

Specified by:

getMethod in class AmpActorContext

getQueryTimeout

public long getQueryTimeout()

setQueryTimeout

public void setQueryTimeout(long timeout)

send

public final 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

query

public void query(AmpMethodRef methodRef,
                  java.lang.Object[] args,
                  AmpQueryCallback cb,
                  long timeout)

Specified by:

close

public void close()

Registers a callback future.

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object

handleAlarm

public void handleAlarm(Alarm alarm)

Description copied from interface: AlarmListener

Handles a callback from an alarm.

Specified by:

handleAlarm in interface AlarmListener
