virtual Standard_EXPORT Standard_Integer NbSubExpressions () const =0
 Returns the number of sub-expressions contained
in <me> ( >= 0)
.
virtual Standard_EXPORT const
Handle_Expr_GeneralExpression & 
SubExpression (const Standard_Integer I) const =0
 Returns the -th sub-expression of <me>
raises OutOfRange if > NbSubExpressions(me)
.

virtual Standard_EXPORT Handle_Expr_GeneralExpression Simplified () const =0
 Returns a GeneralExpression after replacement of
NamedUnknowns by an associated expression and after
values computation.
.
virtual Standard_EXPORT Handle_Expr_GeneralExpression ShallowSimplified () const =0
 Returns a GeneralExpression after a simplification
of the arguments of <me>.
.
virtual Standard_EXPORT Handle_Expr_GeneralExpression Copy () const =0
 Returns a copy of <me> having the same unknowns and
functions.
.
virtual Standard_EXPORT Standard_Boolean ContainsUnknowns () const =0
 Tests if <me> contains NamedUnknowns.
.
virtual Standard_EXPORT Standard_Boolean Contains (const Handle(Expr_GeneralExpression)&exp) const =0
 Tests if <exp> is contained in <me>.
.
virtual Standard_EXPORT Standard_Boolean IsLinear () const =0
 Tests if <me> is linear on every NamedUnknown it
contains.
.
virtual Standard_EXPORT 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 Standard_EXPORT Standard_Boolean IsIdentical (const Handle(Expr_GeneralExpression)&Other) const =0
 Tests if <me> and <other> define the same expression.
Warning: This method does not include any simplification before
testing. It could also be very slow; to be used
carefully.

.
virtual Standard_EXPORT void Replace (const Handle(Expr_NamedUnknown)&var, const Handle(Expr_GeneralExpression)&with)=0
 Replaces all occurences of with copies of <with>
in <me>. Copies of <with> are made with the Copy() method.

 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.
.
Standard_EXPORT Standard_Real EvaluateNumeric () const
 Returns the value of <me> (as a Real) by
replacement of <vars> by <vals>.
