Public Member Functions
virtual Standard_Integer	NbOfVariables () const =0
	Returns the number of variables of <me>.

virtual Handle< Expr_NamedUnknown >	Variable (const Standard_Integer index) const =0
	Returns the variable denoted by <index> in <me>. Raises OutOfRange if index > NbOfVariables.

virtual Handle< Expr_GeneralFunction >	Copy () const =0
	Returns a copy of <me> with the same form.

virtual Handle< Expr_GeneralFunction >	Derivative (const Handle< Expr_NamedUnknown > &var) const =0
	Returns Derivative of <me> for variable .

virtual Handle< Expr_GeneralFunction >	Derivative (const Handle< Expr_NamedUnknown > &var, const Standard_Integer deg) const =0
	Returns Derivative of <me> for variable with degree <deg>.

virtual Standard_Real	Evaluate (const Expr_Array1OfNamedUnknown &vars, const TColStd_Array1OfReal &vals) const =0
	Computes the value of <me> with the given variables. Raises NotEvaluable if <vars> does not match all variables of <me>.

virtual Standard_Boolean	IsIdentical (const Handle< Expr_GeneralFunction > &func) const =0
	Tests if <me> and <func> are similar functions (same name and same used expression).

virtual Standard_Boolean	IsLinearOnVariable (const Standard_Integer index) const =0
	Tests if <me> is linear on variable on range <index>

virtual TCollection_AsciiString	GetStringName () const =0

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.
