class StrongComponants  from IFGraph  inherits SubPartsIterator

    	---Purpose : determines strong componants of a graph, that is
    	--           isolated entities (single componants) or loops

uses Graph

is

    Create (agraph : Graph; whole : Boolean) returns StrongComponants;
    ---Purpose : creates with a Graph, and will analyse :
    --           whole True  : all the contents of the Model
    --           whole False : sub-parts which will be given later

    Evaluate (me : in out) is redefined;
    ---Purpose : does the computation

    	-- --   Iteration : More-Next-etc... will give strong componants

end StrongComponants;
