Method Detail

formatByte

public static Byte formatByte(String value)

Checks if the value can safely be converted to a byte primitive.

Parameters: value The value validation is being performed on.

formatCreditCard

public static Long formatCreditCard(String value)

Checks if the field is a valid credit card number.

Reference Sean M. Burke's script.

Parameters: value The value validation is being performed on.

formatDate

public static Date formatDate(String value, Locale locale)

Checks if the field is a valid date. The Locale is used with java.text.DateFormat. The setLenient 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)

formatDate

public static Date formatDate(String value, String datePattern, 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 setLenient 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.
