20 * This is the base class for a number of classes that generate arbitrary hash
21 * numbers for complex objects, based fundamentally on a sequence of integers.
22 *
23 * There are no virtual functions here, for performance reasons; it is
24 * generally desirable to generate hash numbers as quickly as possible. The
25 * derived classes must redefine all the basic functionality.
26 *
27 * Thus, a compile-time decision must be made for the kind of HashGenerator
28 * that is appropriate for a particular class.
