public class SubclassableTuple

extends SuperTuple

A SubclassableTuple is an ordered sequence of Fields, and implements the subclassable version. For this class, just the fact that SubclassableTuple isn't final is enough to enforce what we're looking for.

Subclasses could override the matches() method to implement any exotic behavior, but recall that matches() is called on the requesting template, rather than the tuple in the tuplespace. This maintains the property of communication orthogonality, i.e. the creator of a tuple has no control over its destination, while the reciever has the flexibility to choose which tuple to recieve.
