get_data_set

Get the DataModelIter object represented the current selected row in this.

This function may return either null or an invalid iterator (see is_valid) if the selection cannot be represented by a single selected row.

Note that the returned DataModelIter is actually an iterator iterating on the DataModel returned by the get_model method.

Parameters:

this	an object which implements the DataSelector interface

Returns:

a pointer to a DataModelIter object, or null
