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

|
---Purpose : Creates a SelectRootComps
|
|
|
|
RootResult (me; G : Graph) returns EntityIterator is redefined;
|
|
---Purpose : Returns the list of local root strong componants, by one
|
|
-- Entity par componant. It is redefined for a purpose of
|
|
-- effeciency : calling a Sort routine for each Entity would
|
|
-- cost more ressource than to work in once using a Map
|
|
-- RootResult takes in account the Direct status
|
|
|
|
HasUniqueResult (me) returns Boolean is redefined protected;
|
|
---Purpose : Returns True, RootResult assuring uniqueness
|
|
|
|
Sort (me; rank : Integer; ent : Transient; model : InterfaceModel)
|
|
returns Boolean;
|
|
---Purpose : Returns always True, because RootResult has done work

ExtractLabel (me) returns AsciiString from TCollection;
|
|
---Purpose : Returns a text defining the criterium : "Local Root Componants"
