Class StrMinMax

  • All Implemented Interfaces:
    CellProcessor, StringCellProcessor

    public class StrMinMax
    extends CellProcessorAdaptor
    implements StringCellProcessor
    This constraint ensures that the input data has a string length between the supplied min and max values (both inclusive). Should the input be anything different from a String, it will be converted to a string using the input's toString() method.

      Constructor Description
      StrMinMax​(long min, long max)
      Constructs a new StrMinMax processor, which ensures that the input data has a string length between the supplied min and max values (both inclusive).
      StrMinMax​(long min, long max, CellProcessor next)
      Constructs a new StrMinMax processor, which ensures that the input data has a string length between the supplied min and max values (both inclusive), then calls the next processor in the chain.

      • StrMinMax

        public StrMinMax​(long min,
                         long max)
        Constructs a new StrMinMax processor, which ensures that the input data has a string length between the supplied min and max values (both inclusive).
        Parameters:
        min - the minimum String length
        max - the maximum String length
        Throws:
        java.lang.IllegalArgumentException - if max < min, or min is < 0

      • execute

        public java.lang.Object execute​(java.lang.Object value,
                                        CsvContext context)
        This method is invoked by the framework when the processor needs to process data or check constraints.
        Specified by:
        execute in interface CellProcessor
        Parameters:
        value - the value to be processed
        context - the CSV context
        Returns:
        the result of cell processor execution
        Throws:
