Class RecurValidator

java.lang.Object

net.fortuna.ical4j.validate.RecurValidator

All Implemented Interfaces:

Serializable, Validator<Recur<?>>

public class RecurValidator
extends Object
implements Validator<Recur<?>>

This validator provides semantic recurrence rule validation according to the RFC5545 specification excerpt listed below.

       The table below summarizes the dependency of BYxxx rule part
       expand or limit behavior on the FREQ rule part value.

       The term "N/A" means that the corresponding BYxxx rule part MUST
       NOT be used with the corresponding FREQ value.

       BYDAY has some special behavior depending on the FREQ value and
       this is described in separate notes below the table.

                for MONTHLY.

       Note 2:  Limit if BYYEARDAY or BYMONTHDAY is present; otherwise,
                special expand for WEEKLY if BYWEEKNO present; otherwise,
                special expand for MONTHLY if BYMONTH present; otherwise,
                special expand for YEARLY.
