AttributeValue (AWS Java SDK for Amazon DynamoDB 1.9.9 API)

java.lang.Object
- com.amazonaws.services.dynamodbv2.model.AttributeValue

All Implemented Interfaces:

Serializable
```
public class AttributeValue
extends Object
implements Serializable
```
Represents the data for an attribute. You can set one, and only one, of the elements.

Each attribute in an item is a name-value pair. An attribute can be single-valued or multi-valued set. For example, a book item can have title and authors attributes. Each book has one title but can have many authors. The multi-valued attribute is a set; duplicate values are not allowed.
