      • formatDate

        public static java.util.Date formatDate​(java.lang.String value,

        Checks if the field is a valid date.

        The Locale is used with java.text.DateFormat. The DateFormat.setLenient(boolean) method is set to false for all.

        Parameters:
        value - The value validation is being performed on.
        locale - The Locale to use to parse the date (system default if null)
        Returns:
        the converted Date value.

      • formatDate

        public static java.util.Date formatDate​(java.lang.String value,

                                        boolean strict)
        Checks if the field is a valid date.

        The pattern is used with java.text.SimpleDateFormat. If strict is true, then the length will be checked so '2/12/1999' will not pass validation with the format 'MM/dd/yyyy' because the month isn't two digits. The DateFormat.setLenient(boolean) method is set to false for all.

        Parameters:
        value - The value validation is being performed on.
        datePattern - The pattern passed to SimpleDateFormat.
        strict - Whether or not to have an exact match of the datePattern.
        Returns:
        the converted Date value.

      • formatCreditCard

        public static java.lang.Long formatCreditCard​(java.lang.String value)

        Reference Sean M. Burke's script.

        Parameters:
