private static final DateValidator DATE_VALIDATOR
Singleton instance of this class.

isValid
public boolean isValid(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.
- true if the date is valid.
isValid
public boolean isValid(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.
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.
- true if the date is valid.
