  • Method Details

    • hasAlarmNames

      public final boolean hasAlarmNames()
      For responses, this returns true if the service returned a value for the AlarmNames 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.

    • alarmNames

      public final List<String> alarmNames()

      The names of the alarms to retrieve information about.

      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 hasAlarmNames() method.

      Returns:
      The names of the alarms to retrieve information about.

    • alarmNamePrefix

      public final String alarmNamePrefix()

      An alarm name prefix. If you specify this parameter, you receive information about all alarms that have names that start with this prefix.

      If this parameter is specified, you cannot specify AlarmNames.

      Returns:
      An alarm name prefix. If you specify this parameter, you receive information about all alarms that have names that start with this prefix.

      If this parameter is specified, you cannot specify AlarmNames.

    • alarmTypes

      public final List<AlarmType> alarmTypes()

      Use this parameter to specify whether you want the operation to return metric alarms or composite alarms. If you omit this parameter, only metric alarms are returned, even if composite alarms exist in the account.

      For example, if you omit this parameter or specify MetricAlarms, the operation returns only a list of metric alarms. It does not return any composite alarms, even if composite alarms exist in the account.

      If you specify CompositeAlarms, the operation returns only a list of composite alarms, and does not return any metric alarms.

      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 hasAlarmTypes() method.

      Returns:
      Use this parameter to specify whether you want the operation to return metric alarms or composite alarms. If you omit this parameter, only metric alarms are returned, even if composite alarms exist in the account.

      For example, if you omit this parameter or specify MetricAlarms, the operation returns only a list of metric alarms. It does not return any composite alarms, even if composite alarms exist in the account.

      If you specify CompositeAlarms, the operation returns only a list of composite alarms, and does not return any metric alarms.

    • hasAlarmTypes

      public final boolean hasAlarmTypes()
      For responses, this returns true if the service returned a value for the AlarmTypes 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.

    • alarmTypesAsStrings

      public final List<String> alarmTypesAsStrings()

      Use this parameter to specify whether you want the operation to return metric alarms or composite alarms. If you omit this parameter, only metric alarms are returned, even if composite alarms exist in the account.

      For example, if you omit this parameter or specify MetricAlarms, the operation returns only a list of metric alarms. It does not return any composite alarms, even if composite alarms exist in the account.

      If you specify CompositeAlarms, the operation returns only a list of composite alarms, and does not return any metric alarms.

    • childrenOfAlarmName

      public final String childrenOfAlarmName()

      If you use this parameter and specify the name of a composite alarm, the operation returns information about the "children" alarms of the alarm you specify. These are the metric alarms and composite alarms referenced in the AlarmRule field of the composite alarm that you specify in ChildrenOfAlarmName. Information about the composite alarm that you name in ChildrenOfAlarmName is not returned.

      If you specify ChildrenOfAlarmName, you cannot specify any other parameters in the request except for MaxRecords and NextToken. If you do so, you receive a validation error.

      Only the Alarm Name, ARN, StateValue (OK/ALARM/INSUFFICIENT_DATA), and StateUpdatedTimestamp information are returned by this operation when you use this parameter. To get complete information about these alarms, perform another DescribeAlarms operation and specify the parent alarm names in the AlarmNames parameter.

      Returns:

      Specified by:
      toBuilder in interface ToCopyableBuilder<DescribeAlarmsRequest.Builder,DescribeAlarmsRequest>
      Specified by:
      toBuilder in class CloudWatchRequest
      Returns:
      a builder for type T

    • builder

      public static DescribeAlarmsRequest.Builder builder()

    • serializableBuilderClass

      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.
