17 class SCRoots from IFGraph inherits StrongComponants
19 ---Purpose : determines strong componants in a graph which are Roots
25 Create (agraph : Graph; whole : Boolean) returns SCRoots;
26 ---Purpose : creates with a Graph, and will analyse :
27 -- whole True : all the contents of the Model
28 -- whole False : sub-parts which will be given later
30 Create (subparts : in out StrongComponants);
31 ---Purpose : creates from a StrongComponants which was already computed
33 Evaluate (me : in out) is redefined;
34 ---Purpose : does the computation
36 -- -- Iteration : More-Next-etc... gives Roots (either Loop or not)
