Class RollingCalendar

  • All Implemented Interfaces:
    java.io.Serializable, java.lang.Cloneable, java.lang.Comparable<java.util.Calendar>
    public class RollingCalendar
extends java.util.GregorianCalendar
    RollingCalendar is a helper class to TimeBasedRollingPolicy or similar timed-based rolling policies. Given a periodicity type and the current time, it computes the start of the next interval (i.e. the triggering date).
