// Class : HashGeneratorBase
|
|
// Description : This is the base class for a number of classes that
|
|
// generate arbitrary hash numbers for complex objects,
|
|
// based fundamentally on a sequence of integers.
|
|
//
|
|
// There are no virtual functions here, for performance
|
|
// reasons; it is generally desirable to generate hash
|
|
// numbers as quickly as possible. The derived classes
|
|
// must redefine all the basic functionality.
|
|
//
|
|
// Thus, a compile-time decision must be made for the
|
|
// kind of HashGenerator that is appropriate for a
|
|
// particular class.
