  • Method Details

    • values

      public static ErrorCorrectionLevel[] values()
      Returns an array containing the constants of this enum type, in the order they are declared.
      Returns:
      an array containing the constants of this enum type, in the order they are declared

    • valueOf

      public static ErrorCorrectionLevel valueOf​(String name)
      Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)
      Parameters:
      name - the name of the enum constant to be returned.
      Returns:
      the enum constant with the specified name
      Throws:
      IllegalArgumentException - if this enum type has no constant with the specified name
      NullPointerException - if the argument is null

    • getBits

      public int getBits()

    • forBits

      public static ErrorCorrectionLevel forBits​(int bits)
      Parameters:
      bits - int containing the two bits encoding a QR Code's error correction level
      Returns:
      ErrorCorrectionLevel representing the encoded error correction level
