23class SelectRoots from IFSelect inherits SelectExtract
25 ---Purpose : A SelectRoots sorts the Entities which are local roots of a
26 -- set of Entities (not shared by other Entities inside this set,
27 -- even if they are shared by other Entities outside it)
29uses AsciiString from TCollection, InterfaceModel, EntityIterator, Graph
33 Create returns mutable SelectRoots;
34 ---Purpose : Creates a SelectRoots
36 RootResult (me; G : Graph) returns EntityIterator is redefined;
37 ---Purpose : Returns the list of local roots. It is redefined for a purpose
38 -- of effeciency : calling a Sort routine for each Entity would
39 -- cost more ressource than to work in once using a Map
40 -- RootResult takes in account the Direct status
42 HasUniqueResult (me) returns Boolean is redefined protected;
43 ---Purpose : Returns True, because RootResult assures uniqueness
45 Sort (me; rank : Integer; ent : Transient; model : InterfaceModel)
46 returns Boolean;
47 ---Purpose : Returns always True, because RootResult has done work
49 ExtractLabel (me) returns AsciiString from TCollection;
50 ---Purpose : Returns a text defining the criterium : "Local Root Entities"
