Subject: bijective association
Date: Sun, 05 Aug 2007 12:40:23 +0200	[thread overview]
Message-ID: <46B5A917.1090303@menta.net> (raw)

Hello,

Please, knows someone if there are any module who implements a bijective 
association ( 'a <=> 'b)?

functions should be something like (assuming 't is the type of the 
association):
add : 't -> 'a -> 'b -> 't
find_a  : 't -> 'a -> 'b
find_b : 't -> 'b -> 'a
remove : 't -> 'a -> 't
...

If not, which one could be the best option: use two associative lists, 
two maps, two hash tables or others?

Thanks a lot.
