class ExclusionFilter from AIS inherits Filter from SelectMgr
---Purpose: A framework to reject or to accept only objects of
-- given types and/or signatures.
-- Objects are stored, and the stored objects - along
-- with the flag settings - are used to define the filter.
-- Objects to be filtered are compared with the stored
-- objects added to the filter, and are accepted or
-- rejected according to the exclusion flag setting.
-- - Exclusion flag on
-- - the function IsOk answers true for all objects,
-- except those of the types and signatures stored
-- in the filter framework
-- - Exclusion flag off
-- - the funciton IsOk answers true for all objects
-- which have the same type and signature as the stored ones.
