# 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
.

## Public Member Functions

Standard_EXPORT | IFSelect_SelectRootComps ()
| Creates a SelectRootComps .
virtual Standard_EXPORT 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_EXPORT 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 .
Standard_EXPORT TCollection_AsciiString | ExtractLabel () const
| Returns a text defining the criterium : "Local Root Componants" .
Standard_EXPORT const | Handle (Standard_Type)&DynamicType() const

## Protected Member Functions

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