public static boolean isBlankOrNull(java.lang.String value)
Checks if the field isn't null and length of the field is greater than zero not including whitespace.
value

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