Annotation Type DynamoDBTypeConvertedEnum

@Retention(value=RUNTIME)
 @Target(value={TYPE,FIELD,METHOD})
public @interface DynamoDBTypeConvertedEnum

Annotation to convert the enumeration value to a string. Please note, there are some risks in distributed systems when using enumerations as attributes intead of simply using a String. When adding new values to the enumeration, the enum only changes must be deployed before the enumeration value can be persisted. This will ensure that all systems have the correct code to map it from the item record in DynamoDB to your objects. A minimal example using getter annotations,

 @DynamoDBTable(tableName="TestTable")
 public class TestClass {
     public static enum Status { OPEN, PENDING, CLOSED }

     private String key;
     private Status status;

     @DynamoDBHashKey
     public String getKey() { return key; }
     public void setKey(String key) { this.key = key; }

     @DynamoDBTypeConvertedEnum
     public Status getStatus() { return status; }
     public void setStatus(Date status) { this.status = status; }
 }
