    • Constructor Summary

      Constructors 
      Constructor Description
      RequireHashCode​(int... requiredHashcodes)
      Constructs a new RequireHashCode processor, which converts the input to a String, and ensures that the input's hash function matches any of a given set of hashcodes.
      RequireHashCode​(int[] requiredHashcodes, CellProcessor next)
      Constructs a new RequireHashCode processor, which converts the input to a String, ensures that the input's hash function matches any of a given set of hashcodes, then calls the next processor in the chain.
      RequireHashCode​(int requiredHashcode, CellProcessor next)
      Constructs a new RequireHashCode processor, which converts the input to a String, ensures that the input's hash function matches the supplied hashcode, then calls the next processor in the chain.

      • 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:
        SuperCsvCellProcessorException - if value is null
        SuperCsvConstraintViolationException - if value isn't one of the required hash codes
