/**
*
* PduSubscriber interface for receivePDU () methods.
*
* This is an interface, a list of methods that a class can implement.
* If the class does in fact implement all of the methods declared here,
* it is said to implement the interface.
*
* The interface here consists of a single method, receivePDU(). Presumably
* this object has registered itself with a PDUPublisher object via
* an addListener() method. That object will in turn send PDUs to us.
* The intention here is to closely match the technique and methods
* used in the Java 1.1 event model.
*
* This is an example of the Observer pattern. See _Design Patterns_,
* Gamma, Helm, Johnson, & Vlissides, pp. 293-303.
