      Returns:
      A target tracking scaling policy.

    • 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.

      Returns:
      The Unix timestamp for when the scaling policy was created.

      public final boolean equalsBySdkFields(Object obj)
      Description copied from interface: SdkPojo
      Indicates whether some other object is "equal to" this one by SDK fields. An SDK field is a modeled, non-inherited field in an SdkPojo class, and is generated based on a service model.

      If an SdkPojo class does not have any inherited fields, equalsBySdkFields and equals are essentially the same.

      Specified by:
      equalsBySdkFields in interface SdkPojo
      Parameters:
      obj - the object to be compared with
      Returns:
      true if the other object equals to this object by sdk fields, false otherwise.

    • toString

      public final String toString()
      Returns a string representation of this object. This is useful for testing and debugging. Sensitive data will be redacted from this string using a placeholder value.

      Returns:
      List of SdkField in this POJO. May be empty list but should never be null.
