GdaDataModelIter

typedef struct _GdaDataModelIter GdaDataModelIter;

gda_data_model_iter_new ()

GdaDataModelIter *  gda_data_model_iter_new             (GdaDataModel *model);

Creates a new GdaDataModelIter object which represents a value or a parameter.

gda_data_model_iter_get_value_at ()

const GValue *      gda_data_model_iter_get_value_at    (GdaDataModelIter *iter,
                                                         gint col);

Get the value stored at the column col in iter

const GValue *      gda_data_model_iter_get_value_for_field
                                                        (GdaDataModelIter *iter,

Get the value stored at the column field_name in iter

gda_data_model_iter_is_valid ()

gboolean            gda_data_model_iter_is_valid        (GdaDataModelIter *iter);

Tells if iter is a valid iterator (if it actually corresponds to a valid row in the model)

gda_data_model_iter_set_at_row ()

gboolean            gda_data_model_iter_set_at_row      (GdaDataModelIter *iter,
                                                         gint row);

Synchronizes the values of the parameters in iter with the values at the row row

If row < 0 then iter is not bound to any row of the data model it iters through.

gda_data_model_iter_move_next ()

gboolean            gda_data_model_iter_move_next       (GdaDataModelIter *iter);

Moves iter one row further than where it already is (synchronizes the values of the parameters in iter with the values at the new row).

gda_data_model_iter_move_prev ()

gboolean            gda_data_model_iter_move_prev       (GdaDataModelIter *iter);

Moves iter one row before where it already is (synchronizes the values of the parameters in iter with the values at the new row).

gda_data_model_iter_get_row ()

gint                gda_data_model_iter_get_row         (GdaDataModelIter *iter);

Get the row which iter represents in the data model

gda_data_model_iter_invalidate_contents ()

void                gda_data_model_iter_invalidate_contents
                                                        (GdaDataModelIter *iter);

Declare all the parameters in iter invalid, without modifying the GdaDataModel iter is for or changing the row it represents

gda_data_model_iter_get_column_for_param ()

gint                gda_data_model_iter_get_column_for_param
                                                        (GdaDataModelIter *iter,
                                                         GdaParameter *param);

Get the column number in the GdaDataModel for which iter is an iterator as represented by the param parameter

gda_data_model_iter_get_param_for_column ()

GdaParameter *      gda_data_model_iter_get_param_for_column
                                                        (GdaDataModelIter *iter,
