Details

You must call the _setNumberOfColumns method before passing the identifier of this Data Set Data Vector instance to any methods of the Data Set Model class. This method initializes the column information. Passing an instance of the Data Set Data Vector class to the Data Set Model class before calling this method results in a program halt. The _setNumberOfColumns method should be called after a call to _setDataset on the instance of the Data Set Model class.
