Class NotNull
- java.lang.Object
-
- org.supercsv.cellprocessor.CellProcessorAdaptor
-
- org.supercsv.cellprocessor.constraint.NotNull

- All Implemented Interfaces:
BoolCellProcessor
,CellProcessor
,DateCellProcessor
,DoubleCellProcessor
,LongCellProcessor
,StringCellProcessor
public class NotNull extends CellProcessorAdaptor implements BoolCellProcessor, DateCellProcessor, DoubleCellProcessor, LongCellProcessor, StringCellProcessor
This processor ensures that the input is not null.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.

NotNull
public NotNull()
Constructs a new NotNull which ensures that the input is not null.
-
NotNull
public NotNull(CellProcessor next)
Constructs a new NotNull which ensures that the input is not null, then calls the next processor in the chain. All other processor should check for null inputs, so this constructor is not typically required.- Parameters:
next
- the next processor in the chain
