Class 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.
