GenericTypeValidator

public GenericTypeValidator()

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.

formatShort

public static Short formatShort(String value)

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

Parameters:

value - The value validation is being performed on.

formatInt

public static Integer formatInt(String value)

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

Parameters:

value - The value validation is being performed on.

formatLong

public static Long formatLong(String value)

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

Parameters:

value - The value validation is being performed on.

formatFloat

public static Float formatFloat(String value)

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

Parameters:

value - The value validation is being performed on.

formatDouble

public static Double formatDouble(String value)

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

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.

formatCreditCard

public static Long formatCreditCard(String value)

Checks if the field is a valid credit card number.
