23class SelectRootComps from IFSelect inherits SelectExtract
24
25 ---Purpose : A SelectRootComps sorts the Entities which are part of Strong
26 -- Componants, local roots of a set of Entities : they can be
27 -- Single Componants (containing one Entity) or Cycles
28 -- This class gives a more secure result than SelectRoots (which
29 -- considers only Single Componants) but is longer to work : it
30 -- can be used when there can be or there are cycles in a Model
31 -- For each cycle, one Entity is given arbitrarily
32 -- Reject works as for SelectRoots : Strong Componants defined in
33 -- the input list which are not local roots are given

38
39 Create returns mutable SelectRootComps;
40 ---Purpose : Creates a SelectRootComps
41
42 RootResult (me; G : Graph) returns EntityIterator is redefined;
43 ---Purpose : Returns the list of local root strong componants, by one
44 -- Entity par componant. It is redefined for a purpose of
45 -- effeciency : calling a Sort routine for each Entity would
46 -- cost more ressource than to work in once using a Map
47 -- RootResult takes in account the Direct status
48
49 HasUniqueResult (me) returns Boolean is redefined protected;
50 ---Purpose : Returns True, RootResult assuring uniqueness
51
52 Sort (me; rank : Integer; ent : Transient; model : InterfaceModel)
53 returns Boolean;
54 ---Purpose : Returns always True, because RootResult has done work
55
56 ExtractLabel (me) returns AsciiString from TCollection;
57 ---Purpose : Returns a text defining the criterium : "Local Root Componants"
