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.
value
- The value validation is being performed on.public static boolean matchRegexp(String value, String regexp)
Checks if the value matches the regular expression.

value
- The value validation is being performed on.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.
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.public static boolean isDate(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.

Checks if a field has a valid e-mail address.
value
- The value validation is being performed on.public static boolean isUrl(String value)
Checks if a field is a valid url address.
If you need to modify what is considered valid then consider using the UrlValidator directly.
