18 | |
19 | ---Purpose : determines strong componants of a graph, that is |
20 | -- isolated entities (single componants) or loops |
21 | |
22 | uses Graph |
23 | |
24 | is |
25 | |
26 | Create (agraph : Graph; whole : Boolean) returns StrongComponants; |
27 | ---Purpose : creates with a Graph, and will analyse : |
28 | -- whole True : all the contents of the Model |
29 | -- whole False : sub-parts which will be given later |
30 | |
31 | Evaluate (me : in out) is redefined; |
32 | ---Purpose : does the computation |
33 | |
34 | -- -- Iteration : More-Next-etc... will give strong componants |
