Public Member Functions
	IFSelect_SelectUnion ()
	Creates an empty SelectUnion.

Interface_EntityIterator	RootResult (const Interface_Graph &G) const override
	Returns the list of selected Entities, which is the addition result from all input selections. Uniqueness is guaranteed.

TCollection_AsciiString	Label () const override
	Returns a text defining the criterium : "Union (OR)".

Public Member Functions inherited from IFSelect_SelectCombine
Standard_Integer	NbInputs () const
	Returns the count of Input Selections.

Handle< IFSelect_Selection >	Input (const Standard_Integer num) const
	Returns an Input Selection, given its rank in the list.

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 :

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_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_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.

void	FillIterator (IFSelect_SelectionIterator &iter) const override
	Puts in an Iterator the Selections from which "me" depends That is to say, the list of Input Selections.

Public Member Functions inherited from IFSelect_Selection
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.

Standard_Transient &	operator= (const Standard_Transient &)
	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.

virtual void	Delete () const
	Memory deallocator for transient classes.

Additional Inherited Members
Public Types inherited from Standard_Transient
typedef void	base_type
	Returns a type descriptor about this object.

Static Public Member Functions inherited from Standard_Transient
static constexpr const char *	get_type_name ()
	Returns a type descriptor about this object.

static const opencascade::handle< Standard_Type > &	get_type_descriptor ()
	Returns type descriptor of Standard_Transient class.

Protected Member Functions inherited from IFSelect_SelectCombine
	IFSelect_SelectCombine ()
	Defines an empty SelectCombine.

virtual Standard_Boolean	HasUniqueResult () const override
	Returns always True, because RootResult gives a Unique list.
