CellProcessor
,StringCellProcessor
public class StrNotNullOrEmpty extends CellProcessorAdaptor implements StringCellProcessor
This processor checks if the input is null or an empty string, and raises an exception in that case. In all other cases, the next processor in the chain is invoked.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.
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.
