public class NotNull extends CellProcessorAdaptor implements BoolCellProcessor, DateCellProcessor, DoubleCellProcessor, LongCellProcessor, StringCellProcessor
You should only use this processor when a column must be non-null, but you do not need to apply any other processor to the column (i.e. a mandatory String column with no other conversions or constraints)
If you apply other processors to the column, you can safely omit this processor as all other processors should do a null-check on its input.
