Class StrMinMax

java.lang.Object
org.supercsv.cellprocessor.CellProcessorAdaptor
org.supercsv.cellprocessor.constraint.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.

    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:
      IllegalArgumentException - if max < min, or min is < 0

    • StrMinMax

      public 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.
      Parameters:
      min - the minimum String length
      max - the maximum String length
      next - the next processor in the chain
      Throws:
      NullPointerException - if next is null
      IllegalArgumentException - if max < min, or min is < 0

    • checkPreconditions

      private static void checkPreconditions(long min, long max)
      Checks the preconditions for creating a new StrMinMax processor.
      Parameters:
      min - the minimum String length
      max - the maximum String length
      Throws:
      IllegalArgumentException - if max < min, or min is < 0

    • execute

      public Object execute(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 length < min or length > max
