	IGESSelect_SelectBasicGeom (const Standard_Integer mode)

Standard_Boolean	Explore (const Standard_Integer level, const Handle< Standard_Transient > &ent, const Interface_Graph &G, Interface_EntityIterator &explored) const override
	Explores an entity, to take its contained Curves 3d Works recursively.

TCollection_AsciiString	ExploreLabel () const override
	Returns a text defining the criterium : "Curves 3d" or "Basic Geometry".

Public Member Functions inherited from IFSelect_SelectExplore
Standard_Integer	Level () const
	Returns the required exploring level.

Interface_EntityIterator	RootResult (const Interface_Graph &G) const override
	Returns the list of selected entities. Works by calling the method Explore on each input entity : it can be rejected, taken for output, or to explore. If the maximum level has not yet been attained, or if no max level is specified, entities to be explored are themselves used as if they were input.

TCollection_AsciiString	Label () const override
	Returns a text saying "(Recursive)" or "(Level nn)" plus specific criterium returned by ExploreLabel (see below)

void	SetInput (const Handle< IFSelect_Selection > &sel)
	Defines or Changes the Input Selection.

Handle< IFSelect_Selection >	Input () const
	Returns the Input Selection.

Standard_Boolean	HasInput () const
	Returns True if the Input Selection is defined, False else.

Standard_Boolean	HasAlternate () const
	Tells if an Alternate List has been set, i.e. : the Alternate Definition is present and set.

Handle< IFSelect_SelectPointed > &	Alternate ()
	Returns the Alternate Definition It is returned modifiable, hence an already defined SelectPointed can be used But if it was not yet defined, it is created the first time.

Interface_EntityIterator	InputResult (const Interface_Graph &G) const
	Returns the Result determined by Input Selection, as Unique if Input Selection is not defined, returns an empty list.

void	FillIterator (IFSelect_SelectionIterator &iter) const override
	Puts in an Iterator the Selections from which "me" depends This list contains one Selection : the InputSelection.

Interface_EntityIterator	UniqueResult (const Interface_Graph &G) const
	Returns the list of selected entities, each of them being unique. Default definition works from RootResult. According HasUniqueResult, UniqueResult returns directly RootResult, or build a Unique Result from it with a Graph.

virtual Interface_EntityIterator	CompleteResult (const Interface_Graph &G) const
	Returns the list of entities involved by a Selection, i.e. UniqueResult plus the shared entities (directly or not)

Public Member Functions inherited from Standard_Transient
	Standard_Transient ()
	Empty constructor.

	Standard_Transient (const Standard_Transient &)
	Copy constructor – does nothing.

	Assignment operator, needed to avoid copying reference counter.

virtual	~Standard_Transient ()
	Destructor must be virtual.

virtual const opencascade::handle< Standard_Type > &	DynamicType () const
	Returns a type descriptor about this object.

Standard_Boolean	IsInstance (const opencascade::handle< Standard_Type > &theType) const
	Returns a true value if this is an instance of Type.

Standard_Boolean	IsInstance (const Standard_CString theTypeName) const
	Returns a true value if this is an instance of TypeName.

Standard_Boolean	IsKind (const opencascade::handle< Standard_Type > &theType) const
	Returns true if this is an instance of Type or an instance of any class that inherits from Type. Note that multiple inheritance is not supported by OCCT RTTI mechanism.

Standard_Boolean	IsKind (const Standard_CString theTypeName) const
	Returns true if this is an instance of TypeName or an instance of any class that inherits from TypeName. Note that multiple inheritance is not supported by OCCT RTTI mechanism.

Standard_Transient *	This () const
	Returns non-const pointer to this object (like const_cast). For protection against creating handle to objects allocated in stack or call from constructor, it will raise exception Standard_ProgramError if reference counter is zero.

Standard_Integer	GetRefCount () const noexcept
	Get the reference counter of this object.

void	IncrementRefCounter () noexcept
	Increments the reference counter of this object.

Standard_Integer	DecrementRefCounter () noexcept
	Decrements the reference counter of this object; returns the decremented value.

	Returns True if RootResult guarantees uniqueness for each Entity. Called by UniqueResult. Default answer is False. Can be redefined.

Detailed Description

This selection returns the basic geometric elements contained in an IGES Entity Intended to run a "quick" transfer. I.E. :

for a Group, considers its Elements
for a Trimmed or Bounded Surface or a Face (BREP), considers the 3D curves of each of its loops
for a Plane (108), considers its Bounding Curve
for a Curve itself, takes it

Also, FREE surfaces are taken, because curve 3d is known for them. (the ideal should be to have their natural bounds)

If <curvesonly> is set, ONLY curves-3d are returned
