IFSelect_SelectRootComps Class Reference

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

 IFSelect_SelectRootComps ()
 Creates a SelectRootComps

virtual Interface_EntityIterator RootResult (const Interface_Graph &G) const
 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

Standard_Boolean Sort (const Standard_Integer rank, const Handle< Standard_Transient > &ent, const Handle< Interface_InterfaceModel > &model) const
 Returns always True, because RootResult has done work

TCollection_AsciiString ExtractLabel () const
 Returns a text defining the criterium : "Local Root Componants"

Protected Member Functions

virtual Standard_Boolean HasUniqueResult () const
 Returns True, RootResult assuring uniqueness
