    Public Member Functions

     ShapeUpgrade_ConvertCurve2dToBezier ()
     Empty constructor.
    void Compute () override
     Converts curve into a list of beziers, and stores the splitting parameters on original curve.
    void Build (const bool Segment) override
     Splits a list of beziers computed by Compute method according the split values and splitting parameters.
    occ::handle< NCollection_HSequence< double > > SplitParams () const
     Returns the list of split parameters in original curve parametrisation.
    Public Member Functions inherited from ShapeUpgrade_SplitCurve2d
     ShapeUpgrade_SplitCurve2d ()
     Empty constructor.
    void Init (const occ::handle< Geom2d_Curve > &C)
     Initializes with pcurve with its first and last parameters.
    void Init (const occ::handle< Geom2d_Curve > &C, const double First, const double Last)
     Initializes with pcurve with its parameters.
    void Build (const bool 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.
    const occ::handle< NCollection_HArray1< occ::handle< Geom2d_Curve > > > & GetCurves () const
    Public Member Functions inherited from ShapeUpgrade_SplitCurve
     ShapeUpgrade_SplitCurve ()
     Empty constructor.
    void Init (const double First, const double Last)
     Initializes with curve first and last parameters.
    void SetSplitValues (const occ::handle< NCollection_HSequence< double > > &SplitValues)
     Sets the parameters where splitting has to be done.
    const occ::handle< NCollection_HSequence< double > > & 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
    void Perform (const bool Segment=true)
     Performs correction/splitting of the curve. First defines splitting values by method Compute(), then calls method Build().
    bool 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_Transientoperator= (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_TransientThis () 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.

    Additional Inherited Members

    typedef void base_type
     Returns a type descriptor about this object.
    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.
