class Cycles  from IFGraph  inherits SubPartsIterator

    	---Purpose : determines strong componants in a graph which are Cycles

uses Graph, StrongComponants

is

    Create (agraph : Graph; whole : Boolean) returns Cycles;
    ---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

    Create (subparts : in out StrongComponants);
    ---Purpose : creates from a StrongComponants which was already computed

    Evaluate (me : in out) is redefined;
    ---Purpose : does the computation. Cycles are StrongComponants which are
    --           not Single

    	-- --   Iteration : More-Next-etc... will give Cycles

end Cycles;
