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.

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.

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.

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.
