Package org.supercsv.cellprocessor.constraint

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.

      Constructor Description
      DMinMax​(double min, double max)
      Constructs a new DMinMax processor, which converts the input to a Double and ensures the value is between the supplied min and max values.
      DMinMax​(double min, double max, DoubleCellProcessor next)
      Constructs a new DMinMax processor, which converts the input to a Double, ensures the value is between the supplied min and max values, then calls the next processor in the chain.
