## Public Member Functions

Standard_EXPORT | IFSelect_SelectPointed ()
| Creates a SelectPointed .
Standard_EXPORT void | Clear ()
| Clears the list of selected items Also says the list is unset All Add* methods and SetList say the list is set .
Standard_EXPORT Standard_Boolean | IsSet () const
| Tells if the list has been set. Even if empty .
Standard_EXPORT void | SetEntity (const Handle(Standard_Transient)&item)
| As SetList but with only one entity If <ent> is Null, the list is said as being set but is empty .
Standard_EXPORT void | SetList (const Handle(TColStd_HSequenceOfTransient)&list)
| Sets a given list to define the list of selected items <list> can be empty or null : in this case, the list is said as being set, but it is empty To use it as an alternate input, one shot : - SetList or SetEntity to define the input list - RootResult to get it - then Clear to drop it .
Standard_EXPORT Standard_Boolean | Add (const Handle(Standard_Transient)&item)
| Adds an item. Returns True if Done, False if <item> is already in the selected list .
Standard_EXPORT Standard_Boolean | Remove (const Handle(Standard_Transient)&item)
| Removes an item. Returns True if Done, False if <item> was not in the selected list .
Standard_EXPORT Standard_Boolean | Toggle (const Handle(Standard_Transient)&item)
| Toggles status of an item : adds it if not pointed or removes it if already pointed. Returns the new status (Pointed or not) .
Standard_EXPORT Standard_Boolean | AddList (const Handle(TColStd_HSequenceOfTransient)&list)
| Adds all the items defined in a list. Returns True if at least one item has been added, False else .
Standard_EXPORT Standard_Boolean | RemoveList (const Handle(TColStd_HSequenceOfTransient)&list)
| Removes all the items defined in a list. Returns True if at least one item has been removed, False else .
Standard_EXPORT Standard_Boolean | ToggleList (const Handle(TColStd_HSequenceOfTransient)&list)
| Toggles status of all the items defined in a list : adds it if not pointed or removes it if already pointed. .
Standard_EXPORT Standard_Integer | Rank (const Handle(Standard_Transient)&item) const
| Returns the rank of an item in the selected list, or 0. .
Standard_EXPORT Standard_Integer | NbItems () const
| Returns the count of selected items .
Standard_EXPORT Handle_Standard_Transient | Item (const Standard_Integer num) const
| Returns an item given its rank, or a Null Handle .
Standard_EXPORT void | Update (const Handle(Interface_CopyControl)&control)
| Rebuilds the selected list. Any selected entity which has a bound result is replaced by this result, else it is removed. .
Standard_EXPORT void | Update (const Handle(IFSelect_Transformer)&trf)
| Rebuilds the selected list, by querying a Transformer (same principle as from a CopyControl) .
Standard_EXPORT Interface_EntityIterator | RootResult (const Interface_Graph &G) const
| Returns the list of selected items. Only the selected entities which are present in the graph are given (this result assures uniqueness). .
Standard_EXPORT TCollection_AsciiString | Label () const
| Returns a text which identifies the type of selection made. It is "Pointed Entities" .
Standard_EXPORT const | Handle (Standard_Type)&DynamicType() const
