## Public Member Functions

Standard_EXPORT Standard_Integer | NbInputs () const
| Returns the count of Input Selections .
Standard_EXPORT Handle_IFSelect_Selection | Input (const Standard_Integer num) const
| Returns an Input Selection, given its rank in the list .
Standard_EXPORT Standard_Integer | InputRank (const Handle(IFSelect_Selection)&sel) const
| Returns the rank of an input Selection, 0 if not in the list. Most generally, its value is meaningless, except for testing the presence of an input Selection : - == 0 if <sel> is not an input for <me> - > 0 if <sel> is an input for <me> .
Standard_EXPORT void | Add (const Handle(IFSelect_Selection)&sel, const Standard_Integer atnum=0)
| Adds a Selection to the filling list By default, adds it to the end of the list A Positive rank less then NbInputs gives an insertion rank (InsertBefore : the new <atnum>th item of the list is <sel>) .
Standard_EXPORT Standard_Boolean | Remove (const Handle(IFSelect_Selection)&sel)
| Removes an input Selection. Returns True if Done, False, if <sel> is not an input for <me> .
Standard_EXPORT Standard_Boolean | Remove (const Standard_Integer num)
| Removes an input Selection, given its rank in the list Returns True if Done, False if <num> is out of range .
Standard_EXPORT void | FillIterator (IFSelect_SelectionIterator &iter) const
| Puts in an Iterator the Selections from which "me" depends That is to say, the list of Input Selections .
Standard_EXPORT const | Handle (Standard_Type)&DynamicType() const

## Protected Member Functions

Standard_EXPORT | IFSelect_SelectCombine ()
| Defines an empty SelectCombine .
virtual Standard_EXPORT Standard_Boolean | HasUniqueResult () const
| Returns always True, because RootResult gives a Unique list .
