Public Member Functions | |
virtual void | ToCoefficients (const Standard_Integer Dimension, const Standard_Integer Degree, const TColStd_Array1OfReal &CoeffinBase, TColStd_Array1OfReal &Coefficients) const =0 |
Convert the polynomial P(t) in the canonical base. | |
virtual void | D0 (const Standard_Real U, TColStd_Array1OfReal &BasisValue)=0 |
Compute the values of the basis functions in u. | |
virtual void | D1 (const Standard_Real U, TColStd_Array1OfReal &BasisValue, TColStd_Array1OfReal &BasisD1)=0 |
Compute the values and the derivatives values of the basis functions in u. | |
virtual void | D2 (const Standard_Real U, TColStd_Array1OfReal &BasisValue, TColStd_Array1OfReal &BasisD1, TColStd_Array1OfReal &BasisD2)=0 |
Compute the values and the derivatives values of the basis functions in u. | |
virtual void | D3 (const Standard_Real U, TColStd_Array1OfReal &BasisValue, TColStd_Array1OfReal &BasisD1, TColStd_Array1OfReal &BasisD2, TColStd_Array1OfReal &BasisD3)=0 |
Compute the values and the derivatives values of the basis functions in u. | |
virtual Standard_Integer | WorkDegree () const =0 |
returns WorkDegree | |
virtual void | ReduceDegree (const Standard_Integer Dimension, const Standard_Integer MaxDegree, const Standard_Real Tol, Standard_Real &BaseCoeff, Standard_Integer &NewDegree, Standard_Real &MaxError) const =0 |
Compute NewDegree <= MaxDegree so that MaxError is lower than Tol. MaxError can be greater than Tol if it is not possible to find a NewDegree <= MaxDegree. In this case NewDegree = MaxDegree. | |
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. | |
Additional Inherited Members | |
Public Types inherited from Standard_Transient | |
typedef void | base_type |
Returns a type descriptor about this object. | |
Static Public Member Functions inherited from Standard_Transient | |
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. | |
