GenericTypeValidator

public GenericTypeValidator()
Method Detail

formatByte

public static java.lang.Byte formatByte(java.lang.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 java.lang.Short formatShort(java.lang.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 java.lang.Integer formatInt(java.lang.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 java.lang.Long formatLong(java.lang.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 java.lang.Float formatFloat(java.lang.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 java.lang.Double formatDouble(java.lang.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 java.util.Date formatDate(java.lang.String value,
                                        java.util.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 java.util.Date formatDate(java.lang.String value,
                                        java.lang.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 java.lang.Long formatCreditCard(java.lang.String value)

Checks if the field is a valid credit card number.
