Method Summary
	`get_definition()` Gets the name of the image file with critical dimension evaluator description.
	`get_name()` Return cdline name (its unique identifier).
	`get_nparams()` Return the number of parameters of `cdline`.
	`get_param_default(param)` Returns: The default parameter value, unrelated to the actual data fitted.
	`get_param_name(param)` Returns: The name of parameter @param.
	`get_param_units(param, siunit_x, siunit_y)` Derives the SI unit of a critical dimension parameter from the units of abscissa and ordinate.
	`UNIMPLEMENTED_fit(n_dat, x, y, n_param, params, err, fixed_param, user_data)` Performs a critical dimension evaulation (fit).
	`UNIMPLEMENTED_get_value(x, params, fres)` Calculates critical dimension function value in a single point with given parameters.

Method Details

Gets the name of the image file with critical dimension evaluator description.

Return cdline name (its unique identifier).

Return the number of parameters of cdline.

Returns: The default parameter value, unrelated to the actual data fitted.

Returns:: The default parameter value, unrelated to the actual data fitted. It is worthless.

Returns: The name of parameter @param.

Derives the SI unit of a critical dimension parameter from the units of abscissa and ordinate.

Parameters:: param - A parameter number. (int); siunit_x - SI unit of abscissa. (SIUnit); siunit_y - SI unit of ordinate. (SIUnit)

Returns:: A newly created SIUnit with the units of the parameter @param. If the units of @param are not representable as SIUnit, the result is unitless (i.e. it will be presented as a mere number).
Since: 2.5

Performs a critical dimension evaulation (fit).

Parameters:: n_dat - The number of data points (number of items in x and y). (int); x - Abscissa points. (const-gdouble*); y - Ordinate points. (const-gdouble*); n_param - The number of parameters. This argument is ignored as the evaluator knows how many parameters it has, it is safe to pass 0. (int); params - Array to store fitted parameter values to. (gdouble*); err - Array to store parameter errros to, may be NULL. (gdouble*); fixed_param - Which parameters should be treated as fixed. It is ignored, pass NULL. (const-gboolean*); user_data - Ignored, pass NULL. (gpointer)

Calculates critical dimension function value in a single point with given parameters.

Parameters:: x - The point to compute value at. (float); params - Evaluator parameter values. (const-gdouble*); fres - Set to True if succeeds, False on failure. (gboolean*)
