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.

Constructor & Destructor Documentation

ShapeUpgrade_SplitCurve()

ShapeUpgrade_SplitCurve::ShapeUpgrade_SplitCurve

(

)

Empty constructor.

Member Function Documentation

Build()

virtual void ShapeUpgrade_SplitCurve::Build ( const bool Segment )

virtual

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.

Reimplemented in ShapeUpgrade_ConvertCurve2dToBezier, ShapeUpgrade_ConvertCurve3dToBezier, ShapeUpgrade_SplitCurve2d, and ShapeUpgrade_SplitCurve3d.

Compute()

virtual void ShapeUpgrade_SplitCurve::Compute ( )

virtual

Calculates points for correction/splitting of the curve.

Reimplemented in ShapeUpgrade_ConvertCurve2dToBezier, ShapeUpgrade_ConvertCurve3dToBezier, ShapeUpgrade_SplitCurve2dContinuity, and ShapeUpgrade_SplitCurve3dContinuity.

Init()

void ShapeUpgrade_SplitCurve::Init	(	const double	First,
		const double	Last )

Initializes with curve first and last parameters.

Perform()

void ShapeUpgrade_SplitCurve::Perform

(

const bool

Segment = true

)

Performs correction/splitting of the curve. First defines splitting values by method Compute(), then calls method Build().

SetSplitValues()

void ShapeUpgrade_SplitCurve::SetSplitValues

(

const occ::handle< NCollection_HSequence< double > > &

SplitValues

)

Sets the parameters where splitting has to be done.

SplitValues()

const occ::handle< NCollection_HSequence< double > > & ShapeUpgrade_SplitCurve::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

Status()

bool ShapeUpgrade_SplitCurve::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.
