      • hasAlarms

        public final boolean hasAlarms()
        For responses, this returns true if the service returned a value for the Alarms property. This DOES NOT check that the value is non-empty (for which, you should check the isEmpty() method on the property). This is useful because the SDK will never return a null collection or map, but you may need to differentiate between the service returning nothing (or null) and the service returning an empty collection or map. For requests, this returns true if a value for the property was specified in the request builder, and false if a value was not specified.
      • alarms

        public final List<Alarm> alarms()

        The CloudWatch alarms associated with the scaling policy.

        Attempts to modify the collection returned by this method will result in an UnsupportedOperationException.

        This method will never return null. If you would like to know whether the service returned this field (so that you can differentiate between null and empty), you can use the hasAlarms() method.

        Returns:
        The CloudWatch alarms associated with the scaling policy.
      • creationTime

        public final Instant creationTime()

        The Unix timestamp for when the scaling policy was created.
