REGEXP_DELIM

public static final String REGEXP_DELIM

Deprecated. Use ValidatorUtils.REGEXP_DELIMITER instead.
Delimiter to put around a regular expression following Perl 5 syntax.

creditCardValidator

private static final CreditCardValidator creditCardValidator

CreditCardValidator used in wrapper method.

urlValidator

private static final UrlValidator urlValidator

UrlValidator used in wrapper method.

getDelimittedRegexp

protected static String getDelimittedRegexp(String regexp)

Deprecated. use ValidatorUtils.getDelimitedRegExp() instead.
Adds a '/' on either side of the regular expression.

isBlankOrNull

public static boolean isBlankOrNull(String value)

Checks if the field isn't null and length of the field is greater than zero not including whitespace.
Parameters:
value - The value validation is being performed on.

isByte

public static boolean isByte(String value)

Checks if the value can safely be converted to a byte primitive.
Parameters:
value - The value validation is being performed on.

isCreditCard

public static boolean isCreditCard(String value)

Checks if the field is a valid credit card number.
Parameters:
value - The value validation is being performed on.

isDate

public static boolean isDate(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 for the date format, defaults to the default system default if null.

isDate

public static boolean isDate(String value,

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.
