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