Public Member Functions
	Expr_FunctionDerivative (const Handle< Expr_GeneralFunction > &func, const Handle< Expr_NamedUnknown > &withX, const Standard_Integer deg)
	Creates a FunctionDerivative of degree <deg> relative to the <withX> variable. Raises OutOfRange if <deg> lower or equal to zero.

	Returns the number of variables of <me>.

Handle< Expr_NamedUnknown >	Variable (const Standard_Integer index) const override
	Returns the variable denoted by <index> in <me>. Raises OutOfRange if <index> greater than NbOfVariables of <me>.

Standard_Real	Evaluate (const Expr_Array1OfNamedUnknown &vars, const TColStd_Array1OfReal &values) const override
	Computes the value of <me> with the given variables. Raises DimensionMismatch if Length(vars) is different from Length(values).

Handle< Expr_GeneralFunction >	Copy () const override
	Returns a copy of <me> with the same form.

Handle< Expr_GeneralFunction >	Derivative (const Handle< Expr_NamedUnknown > &var) const override
	Returns Derivative of <me> for variable .

	Tests if <me> is linear on variable on range <index>

Handle< Expr_GeneralFunction >	Function () const
	Returns the function of which <me> is the derivative.

Standard_Integer	Degree () const
	Returns the degree of derivation of <me>.

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.
