 Expr_UnaryFunction (const Handle< Expr_GeneralFunction > &func, const Handle< Expr_GeneralExpression > &exp)
 Creates me as <func>(<exp>).
Raises exception if <func> is not unary.

Handle_Expr_GeneralFunction Function () const
 Returns the function defining <me>.

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

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

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

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

Handle_Expr_GeneralExpression Derivative (const Handle< Expr_NamedUnknown > &X) const
 returns the derivative on <X> unknown of <me>.

Standard_Real Evaluate (const Expr_Array1OfNamedUnknown &vars, const TColStd_Array1OfReal &vals) 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.

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