 public DateRange getEffectiveRange() { return effectiveRange; }
 public void setEffectiveRange(DateRange effectiveRange) { this.effectiveRange = effectiveRange; }

 @DynamoDBFlattened(attributes={
     @DynamoDBAttribute(mappedBy="start", attributeName="extensionStartDate"),
     @DynamoDBAttribute(mappedBy="end", attributeName="extensionEndDate")})
 public DateRange getExtensionRange() { return extensionRange; }
 public void setExtensionRange(DateRange extensionRange) { this.extensionRange = extensionRange; }
 

Where,

 public class DateRange {
     private Date start;
     private Date end;

     public Date getStart() { return start; }
     public void setStart(Date start) { this.start = start; }
