Package org.supercsv.cellprocessor.constraint

Class LMinMax

  • All Implemented Interfaces:
    CellProcessor, StringCellProcessor
    public class LMinMax
extends CellProcessorAdaptor
implements StringCellProcessor
    Converts the input data to a Long and and ensures the value is between the supplied min and max values (inclusive). If the data has no upper or lower bound, you should use either of MIN or MAX constants provided in the class.

      Constructor Description
      LMinMax​(long min, long max)
      Constructs a new LMinMax processor, which converts the input data to a Long and and ensures the value is between the supplied min and max values.
      LMinMax​(long min, long max, LongCellProcessor next)
      Constructs a new LMinMax processor, which converts the input data to a Long and and ensures the value is between the supplied min and max values, then calls the next processor in the chain.
