Public Member Functions
	ShapeUpgrade_SplitCurve2d ()
	Empty constructor.

void	Init (const Handle< Geom2d_Curve > &C)
	Initializes with pcurve with its first and last parameters.

void	Init (const Handle< Geom2d_Curve > &C, const Standard_Real First, const Standard_Real Last)
	Initializes with pcurve with its parameters.

virtual void	Build (const Standard_Boolean Segment) override
	If Segment is True, the result is composed with segments of the curve bounded by the SplitValues. If Segment is False, the result is composed with trimmed Curves all based on the same complete curve.

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

void	Init (const Standard_Real First, const Standard_Real Last)
	Initializes with curve first and last parameters.

void	SetSplitValues (const Handle< TColStd_HSequenceOfReal > &SplitValues)
	Sets the parameters where splitting has to be done.

const Handle< TColStd_HSequenceOfReal > &	SplitValues () const
	returns all the splitting values including the First and Last parameters of the input curve Merges input split values and new ones into myGlobalKnots

virtual void	Compute ()
	Calculates points for correction/splitting of the curve.

void	Perform (const Standard_Boolean Segment=Standard_True)
	Performs correction/splitting of the curve. First defines splitting values by method Compute(), then calls method Build().

Standard_Boolean	Status (const ShapeExtend_Status status) const
	Returns the status OK - no splitting is needed DONE1 - splitting required and gives more than one segment DONE2 - splitting is required, but gives only one segment (initial) DONE3 - geometric form of the curve or parametrisation is modified.

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.
