Public Member Functions

Standard_EXPORT Expr_NamedFunction (const TCollection_AsciiString &name, const Handle(Expr_GeneralExpression)&exp, const Expr_Array1OfNamedUnknown &vars)
 Creates a function of given variables <vars> with name
<name> defined by the expression <exp>.
.
Standard_EXPORT void SetName (const TCollection_AsciiString &newname)
 Sets the name <newname> to <me>.
.
Standard_EXPORT TCollection_AsciiString GetName () const
 Returns the name assigned to <me>
.
Standard_EXPORT Standard_Integer NbOfVariables () const
 Returns the number of variables of <me>.
.
Standard_EXPORT Handle_Expr_NamedUnknown Variable (const Standard_Integer index) const
 Returns the variable denoted by <index> in <me>.
Raises OutOfRange if <index> is greater than
NbOfVariables of <me>, or less than or equal to zero.
.
Standard_EXPORT Standard_Real Evaluate (const Expr_Array1OfNamedUnknown &vars, const TColStd_Array1OfReal &values) const
 Computes the value of <me> with the given variables.
Raises DimensionMismatch if Length(vars) is different from
Length(values).
.
Standard_EXPORT Handle_Expr_GeneralFunction Copy () const
 Returns a copy of <me> with the same form.
.
Standard_EXPORT Handle_Expr_GeneralFunction Derivative (const Handle(Expr_NamedUnknown)&var) const
 Returns Derivative of <me> for variable .
.

Standard_EXPORT Handle_Expr_GeneralFunction Derivative (const Handle(Expr_NamedUnknown)&var, const Standard_Integer deg) const
 Returns Derivative of <me> for variable with
degree <deg>.
.

Standard_EXPORT Standard_Boolean IsIdentical (const Handle(Expr_GeneralFunction)&func) const
 Tests if <me> and <func> are similar functions (same
name and same used expression).
.
Standard_EXPORT Standard_Boolean IsLinearOnVariable (const Standard_Integer index) const
 Tests if <me> is linear on variable on range <index>
.
Standard_EXPORT TCollection_AsciiString GetStringName () const
Standard_EXPORT Handle_Expr_GeneralExpression Expression () const
 Returns equivalent expression of <me>.
.
Standard_EXPORT void SetExpression (const Handle(Expr_GeneralExpression)&exp)
 Modifies expression of <me>.
Warning: Beware of derivatives. See FunctionDerivative
.
