Last change on this file since 1922:1ee37068316b was 1675:fa89ffb27a6d, checked in by Balazs Dezso, 19 years ago

Redesign of the map adaptors.
/smart reference handling only used by functions/

Better handling of the function objects and functions.


\todo May we use operators instead of the addMap, subMap...?
