                  edu.vub.at.objects.natives.NATMessage

All Implemented Interfaces:

ATAbstractGrammar, ATConversions, ATExpression, ATMessage, ATNil, ATObject, ATStatement, java.io.Serializable

Direct Known Subclasses:

NATAsyncMessage, NATDelegation, NATMethodInvocation

public abstract class NATMessage

extends NATObject

implements ATMessage

Instances of the class NATMessage represent first-class messages. A NATMessage is an abstract class, as it can be either a synchronous method invocation or an asynchronous message send. NATMessages subclass from NATIsolate, such that they represent true AmbientTalk objects.
