Supplier

public class Supplier extends Worker
Represents the supplier component of the sample application. Does some work, and places the results into a queue. This class is identical to smaple.standard.Supplier. We could have used that class in our example. However, it has been copied into the dynamic package so that it may inherit from dynamic.Basic instead of sample.standard.Basic.
