Public Member Functions
	ShapeAnalysis_TransferParameters ()
	Creates empty tool with myShift = 0 and myScale = 1.

	ShapeAnalysis_TransferParameters (const TopoDS_Edge &E, const TopoDS_Face &F)
	Creates a tool and initializes it with edge and face.

virtual void	Init (const TopoDS_Edge &E, const TopoDS_Face &F)
	Initialize a tool with edge and face.

void	SetMaxTolerance (const double maxtol)
	Sets maximal tolerance to use linear recomputation of parameters.

virtual occ::handle< NCollection_HSequence< double > >	Perform (const occ::handle< NCollection_HSequence< double > > &Params, const bool To2d)
	Transfers parameters given by sequence Params from 3d curve to pcurve (if To2d is True) or back (if To2d is False)

virtual double	Perform (const double Param, const bool To2d)
	Transfers parameter given by sequence Params from 3d curve to pcurve (if To2d is True) or back (if To2d is False)

virtual void	TransferRange (TopoDS_Edge &newEdge, const double prevPar, const double currPar, const bool To2d)
	Recomputes range of curves from NewEdge. If Is2d equals True parameters are recomputed by curve2d else by curve3d.

virtual bool	IsSameRange () const
	Returns True if 3d curve of edge and pcurve are SameRange (in default implementation, if myScale == 1 and myShift == 0)

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 ()=default
	Destructor must be virtual.

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

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

bool	IsInstance (const char *const theTypeName) const
	Returns a true value if this is an instance of TypeName.

bool	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.

bool	IsKind (const char *const 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.

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

void	IncrementRefCounter () noexcept
	Increments the reference counter of this object. Uses relaxed memory ordering since incrementing only requires atomicity, not synchronization with other memory operations.

int	DecrementRefCounter () noexcept
	Decrements the reference counter of this object; returns the decremented value. Uses release ordering for the decrement to ensure all writes to the object are visible before the count reaches zero. An acquire fence is added only when the count reaches zero, ensuring proper synchronization before deletion. This is more efficient than using acq_rel for every decrement.

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

Detailed Description

This tool is used for transferring parameters from 3d curve of the edge to pcurve and vice versa.

Default behaviour is to trsnafer parameters with help of linear transformation:

T2d = myShift + myScale * T3d where myScale = ( Last2d - First2d ) / ( Last3d - First3d ) myShift = First2d - First3d * myScale [First3d, Last3d] and [First2d, Last2d] are ranges of edge on curve and pcurve

This behaviour can be redefined in derived classes, for example, using projection.
