Interface LuhnAsGeneratorSpec

All Superinterfaces:
AsGeneratorSpec<String>, GeneratorSpec<String>, LuhnGeneratorSpec, NullableGeneratorSpec<String>
public interface LuhnAsGeneratorSpec extends LuhnGeneratorSpec, AsGeneratorSpec<String>
A spec for generating numbers that pass the Luhn checksum algorithm. This spec supports AsGeneratorSpec.
Since:
3.1.0

  • Method Details

    • length

      LuhnAsGeneratorSpec length(int length)
      Description copied from interface: LuhnGeneratorSpec
      Length of the number to generate (default value is 16).
      Specified by:
      length in interface LuhnGeneratorSpec
      Parameters:
      length - of the value to generate
      Returns:
      spec builder

    • length

      LuhnAsGeneratorSpec length(int min, int max)
      Description copied from interface: LuhnGeneratorSpec
      Generate a number of random length within the specified range.
      Specified by:
      length in interface LuhnGeneratorSpec
      Parameters:
      min - minimum length (inclusive)
      max - maximum length (inclusive)
      Returns:
      spec builder

    • startIndex

      LuhnAsGeneratorSpec startIndex(int startIndex)
      Description copied from interface: LuhnGeneratorSpec
      The start index for calculating the checksum (default value is 0).
      Specified by:
      startIndex in interface LuhnGeneratorSpec
      Parameters:
      startIndex - for calculating the checksum (inclusive)
      Returns:
      spec builder

    • endIndex

      LuhnAsGeneratorSpec endIndex(int endIndex)
      Description copied from interface: LuhnGeneratorSpec
      The end index for calculating the checksum.
      Specified by:
      endIndex in interface LuhnGeneratorSpec
      Parameters:
      endIndex - for calculating the checksum (inclusive)
      Returns:
      spec builder

    • checkDigitIndex

      LuhnAsGeneratorSpec checkDigitIndex(int checkDigitIndex)
      Description copied from interface: LuhnGeneratorSpec
      The index of the check digit in the input. If not specified, the last digit will be used as the check digit.

      If set, the digit at the specified index is used. If set the following must hold true:
      checkDigitIndex >= 0 && (checkDigitIndex < startIndex || checkDigitIndex >= endIndex).

      Specified by:
      checkDigitIndex in interface LuhnGeneratorSpec
      Parameters:
      checkDigitIndex - index of the check digit
      Returns:
      spec builder

    • nullable

      LuhnAsGeneratorSpec nullable()
      Description copied from interface: LuhnGeneratorSpec
      Indicates that null value can be generated.
      Specified by:
      nullable in interface LuhnGeneratorSpec
      Specified by:
      nullable in interface NullableGeneratorSpec<String>
      Returns:
      spec builder
