-- Author: Odile Olivier
-- <odl@sacadox.paris1.matra-dtv.fr>
-- GG : GER61351 17/11/1999 Change SetColor() with a compatible Quantity_Color instead
-- the restricted NameOfColor.
-- GG : BUC60915 05/06/01 Enable to compute the requested arrow size if any
-- in all dimensions, add a field myArrowSizeIsDefined.

deferred class Relation from AIS inherits InteractiveObject from AIS
---Purpose: One of the four types of interactive object in
-- AIS,comprising dimensions and constraints. Serves
-- as the abstract class for the seven relation classes as
-- well as the seven dimension classes.
-- The statuses available for relations between shapes are as follows:
-- - 0 - there is no connection to a shape;
-- - 1 - there is a connection to the first shape;
-- - 2 - there is a connection to the second shape.
-- The connection takes the form of an edge between the two shapes.
