Interface ATAsyncMessage

All Superinterfaces:

ATConversions, ATMessage, ATObject

All Known Implementing Classes:

NATAsyncMessage

public interface ATAsyncMessage

extends ATMessage

Instances of the class ATAsyncMessage represent first-class asynchronous message sends. They encapsulate a receiver object, a selector symbol and a table of arguments. Additionally, a message -- being a first-class object, may be extended with extra fields and behaviour (attachments).

Method Summary

ATObject	base_getReceiver() Messages also have an explicitly named receiver, which may either be a local object, or a representative of an object inside another actor.
ATObject	base_getSender() Signifies the object on behalf of which this asynchronous message is sent.
ATObject	base_process(ATActorMirror inActor) This method is responsible for processing the message in a certain actor.

Method Detail

base_getSender

public ATObject base_getSender()
                        throws InterpreterException

Signifies the object on behalf of which this asynchronous message is sent. For a 'normal' message send, it is bound to the active 'self' object that executed obj<-m().

Throws:

InterpreterException

base_getReceiver

public ATObject base_getReceiver()
                          throws InterpreterException

Messages also have an explicitly named receiver, which may either be a local object, or a representative of an object inside another actor.

Returns:

the receiver of the message

Throws:

InterpreterException

base_process

public ATObject base_process(ATActorMirror inActor)
                      throws InterpreterException

This method is responsible for processing the message in a certain actor. By default, process dispatches to the actor by means of receive. In pseudo-code: def process(act) { (reflect: act).receive(self) }

Throws:

InterpreterException
