Inheritance diagram for Expr_PolyExpression:

Public Member Functions
Standard_Integer	NbOperands () const
	returns the number of operands contained in <me>
const Handle_Expr_GeneralExpression &	Operand (const Standard_Integer index) const
	Returns the <index>-th operand used in <me>. An exception is raised if index is out of range
void	SetOperand (const Handle< Expr_GeneralExpression > &exp, const Standard_Integer index)
	Sets the <index>-th operand used in <me>. An exception is raised if <index> is out of range Raises InvalidOperand if <exp> contains <me>.
Standard_Integer	NbSubExpressions () const
	returns the number of sub-expressions contained in <me> ( >= 2)
const Handle_Expr_GeneralExpression &	SubExpression (const Standard_Integer I) const
	Returns the sub-expression denoted by in <me> Raises OutOfRange if > NbSubExpressions(me)
Standard_Boolean	ContainsUnknowns () const
	Does <me> contains NamedUnknown ?
Standard_Boolean	Contains (const Handle< Expr_GeneralExpression > &exp) const
	Tests if <exp> is contained in <me>.
void	Replace (const Handle< Expr_NamedUnknown > &var, const Handle< Expr_GeneralExpression > &with)
	Replaces all occurences of with <with> in <me> Raises InvalidOperand if <with> contains <me>.
Handle_Expr_GeneralExpression	Simplified () const
	Returns a GeneralExpression after replacement of NamedUnknowns by an associated expression and after values computation.
Protected Member Functions
	Expr_PolyExpression ()
	initialize an empty list of operands.
void	AddOperand (const Handle< Expr_GeneralExpression > &exp)
	Adds an operand to the list of <me>.
void	RemoveOperand (const Standard_Integer index)
	Remove the operand denoted by <index> from the list of <me>. Raises exception if <index> is out of range or if removing operand intend to leave only one or no operand.
