Class DMinMax

java.lang.Object
org.supercsv.cellprocessor.CellProcessorAdaptor
org.supercsv.cellprocessor.constraint.DMinMax
All Implemented Interfaces:
CellProcessor, StringCellProcessor
public class DMinMax extends CellProcessorAdaptor implements StringCellProcessor
Converts the input data to a Double and ensures that number is within a specified numeric range (inclusive). If the data has no upper bound (or lower bound), you should use either of MIN or MAX constants provided in the class.
