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.

Empty constructor.

Member Function Documentation

Build()

virtual void ShapeUpgrade_SplitSurface::Build ( const bool Segment )

virtual

Performs splitting of the supporting surface. If resulting surface is B-Spline and Segment is True, the result is composed with segments of the surface bounded by the U and V SplitValues (method Geom_BSplineSurface::Segment is used). If Segment is False, the result is composed with Geom_RectangularTrimmedSurface all based on the same complete surface. Fields myNbResultingRow and myNbResultingCol must be set to specify the size of resulting grid of surfaces.

Reimplemented in ShapeUpgrade_ConvertSurfaceToBezierBasis.

Compute()

virtual void ShapeUpgrade_SplitSurface::Compute ( const bool Segment = true )

virtual

Calculates points for correction/splitting of the surface.

Reimplemented in ShapeUpgrade_ConvertSurfaceToBezierBasis, ShapeUpgrade_SplitSurfaceAngle, ShapeUpgrade_SplitSurfaceArea, and ShapeUpgrade_SplitSurfaceContinuity.

Init() [1/2]

void ShapeUpgrade_SplitSurface::Init

(

const occ::handle< Geom_Surface > &

S

)

Initializes with single supporting surface.

Init() [2/2]

void ShapeUpgrade_SplitSurface::Init	(	const occ::handle< Geom_Surface > &	S,
		const double	UFirst,
		const double	ULast,
		const double	VFirst,

		const double	theArea = 0. )

Initializes with single supporting surface with bounding parameters.

Perform()

void ShapeUpgrade_SplitSurface::Perform

(

const bool

Segment = true

const

Returns obtained surfaces after splitting as CompositeSurface.

SetUSplitValues()

void ShapeUpgrade_SplitSurface::SetUSplitValues

Sets V parameters where splitting has to be done.

Status()

bool ShapeUpgrade_SplitSurface::Status

(

const ShapeExtend_Status

status

)

const

Returns the status OK - no splitting is needed DONE1 - splitting required and gives more than one patch DONE2 - splitting is required, but gives only single patch (initial) DONE3 - geometric form of the surface or parametrisation is modified.
