public void setChildrenOfAlarmName(String childrenOfAlarmName) {
        this.childrenOfAlarmName = childrenOfAlarmName;
    }
<p>
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
<code>AlarmRule</code> field of the composite alarm that you specify in <code>ChildrenOfAlarmName</code>.
Information about the composite alarm that you name in <code>ChildrenOfAlarmName</code> is not returned.
</p>
<p>
If you specify <code>ChildrenOfAlarmName</code>, you cannot specify any other parameters in the request except
for <code>MaxRecords</code> and <code>NextToken</code>. If you do so, you receive a validation error.
</p>
<note>
<p>
Only the <code>Alarm Name</code>, <code>ARN</code>, <code>StateValue</code> (OK/ALARM/INSUFFICIENT_DATA), and
<code>StateUpdatedTimestamp</code> information are returned by this operation when you use this parameter. To get
complete information about these alarms, perform another <code>DescribeAlarms</code> operation and specify the
parent alarm names in the <code>AlarmNames</code> parameter.
