All Implemented Interfaces:

MessageReceiver

Direct Known Subclasses:

StdSingleServerQueue

public abstract class SingleServerQueue
extends Entity
implements MessageReceiver

SingleServerQueue is an abstract base class for single servers. It provides a non-blocking input port ("input") and a non-blocking (synchronous) output port ("output").

Messages received on the input port are forwarded to the method ReceiveMessage which has to be defined in derived classes. Moreover, it contains an end of service event which is handled by HandleEndOfService that has to defined in subclasses.
