-- D0,D1,D2... Correspond to this restriction.
-- Returns Standard_False (default implementation)
returns Boolean
is redefined;

-- of continuity <S>.

-- The array must provide enough room to accomodate
-- for the parameters. i.e. T.Length() > NbIntervals()
raises

-- =================== To help computation of Tolerance ===============
--
-- Evaluation of error, in 2d space, or on composed function, is
-- difficult. The following methods can help the approximation to
-- make good evaluation and use good tolerances.
--
-- It is not necessary for the following informations to be very
-- precise. A fast evaluation is sufficient.
Resolution(me;
Index : Integer from Standard;
Tol : Real from Standard;
TolU, TolV : out Real from Standard)
---Purpose: Returns the resolutions in the sub-space 2d <Index>
-- This information is usfull to find an good tolerance in
-- 2d approximation.
