|
|
|
---Purpose : FindHasher defines HashCode for Finder, which is : ask a
|
|
-- Finder its HashCode ! Because this is the Finder itself which
|
|

--
|
|
-- This class complies to the template given in TCollection by
|
|
-- MapHasher itself
|
|
|
|
uses Finder
|

HashCode (myclass; K : Finder; Upper : Integer) returns Integer;
|
|
---Purpose : Returns a HashCode in the range <0,Upper> for a Finder :
|
|
-- asks the Finder its HashCode then transforms it to be in the
|
|
-- required range
|
|
|
|
IsEqual (myclass; K1, K2 : Finder) returns Boolean;
