Class Strlen

java.lang.Object
org.supercsv.cellprocessor.CellProcessorAdaptor
org.supercsv.cellprocessor.constraint.Strlen
All Implemented Interfaces:
CellProcessor, StringCellProcessor
public class Strlen extends CellProcessorAdaptor implements StringCellProcessor
This processor ensures that the input String has a length equal to any of the supplied lengths. The length constraints must all be > 0 or an exception is thrown. Lookup time is O(1).
