Public Member Functions
	Expr_Division (const Handle< Expr_GeneralExpression > &exp1, const Handle< Expr_GeneralExpression > &exp2)
	Creates the division <exp1>/<exp2>

Handle< Expr_GeneralExpression >	ShallowSimplified () const override
	Returns a GeneralExpression after a simplification of the arguments of <me>.

Handle< Expr_GeneralExpression >	Copy () const override
	Returns a copy of <me> having the same unknowns and functions.

Standard_Boolean	IsIdentical (const Handle< Expr_GeneralExpression > &Other) const override
	Tests if <me> and <Other> define the same expression. This method does not include any simplification before testing.

Standard_Boolean	IsLinear () const override
	Tests if <me> is linear on every NamedUnknown it contains.

Handle< Expr_GeneralExpression >	Derivative (const Handle< Expr_NamedUnknown > &X) const override
	Returns the derivative on <X> unknown of <me>.

Standard_Real	Evaluate (const Expr_Array1OfNamedUnknown &vars, const TColStd_Array1OfReal &vals) const override
	Returns the value of <me> (as a Real) by replacement of <vars> by <vals>. Raises NotEvaluable if <me> contains NamedUnknown not in <vars> or NumericError if result cannot be computed.

TCollection_AsciiString	String () const override
	returns a string representing <me> in a readable way.

Public Member Functions inherited from Expr_BinaryExpression
const Handle< Expr_GeneralExpression > &	FirstOperand () const

const Handle< Expr_GeneralExpression > &	SecondOperand () const

void	SetFirstOperand (const Handle< Expr_GeneralExpression > &exp)
	Sets first operand of <me> Raises InvalidOperand if exp = me.

void	SetSecondOperand (const Handle< Expr_GeneralExpression > &exp)
	Sets second operand of <me> Raises InvalidOperand if <exp> contains <me>.

Standard_Integer	NbSubExpressions () const override
	returns the number of sub-expressions contained in <me> ( >= 0)

const Handle< Expr_GeneralExpression > &	SubExpression (const Standard_Integer I) const override
	returns the -th sub-expression of <me> raises OutOfRange if > NbSubExpressions(me)

Standard_Boolean	ContainsUnknowns () const override
	Does <me> contain NamedUnknown ?

Standard_Boolean	Contains (const Handle< Expr_GeneralExpression > &exp) const override
	Tests if <me> contains <exp>.

void	Replace (const Handle< Expr_NamedUnknown > &var, const Handle< Expr_GeneralExpression > &with) override
	Replaces all occurrences of with <with> in <me>. Raises InvalidOperand if <with> contains <me>.

Handle< Expr_GeneralExpression >	Simplified () const override
	Returns a GeneralExpression after replacement of NamedUnknowns by an associated expression and after values computation.

Public Member Functions inherited from Expr_GeneralExpression
virtual Standard_Boolean	IsShareable () const
	Tests if <me> can be shared by one or more expressions or must be copied. This method returns False as a default value. To be redefined ( especially for NamedUnknown).

virtual Handle< Expr_GeneralExpression >	NDerivative (const Handle< Expr_NamedUnknown > &X, const Standard_Integer N) const
	Returns the <N>-th derivative on <X> unknown of <me>. Raise OutOfRange if N <= 0.

Standard_Real	EvaluateNumeric () const
	Returns the value of <me> (as a Real) by replacement of <vars> by <vals>. Raises NotEvaluable if <me> contains NamedUnknown not in <vars> or NumericError if result cannot be computed.

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.

Protected Member Functions inherited from Expr_BinaryExpression
void	CreateFirstOperand (const Handle< Expr_GeneralExpression > &exp)
	Sets first operand of <me>

void	CreateSecondOperand (const Handle< Expr_GeneralExpression > &exp)
	Sets second operand of <me> Raises InvalidOperand if <exp> contains <me>.
