AttributeValue (AWS Java SDK for Amazon DynamoDB 1.10.24 API)

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

All Implemented Interfaces:

Serializable, Cloneable
```
public class AttributeValue
extends Object
implements Serializable, Cloneable
```
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.

- Constructor Detail
  - AttributeValue
```
public AttributeValue()
```
    Default constructor for AttributeValue object. Callers should use the setter or fluent setter (with...) methods to initialize the object after creating it.
  - AttributeValue
```
public AttributeValue(String s)
```
    Constructs a new AttributeValue object. Callers should use the setter or fluent setter (with...) methods to initialize any additional object members.
    
    Parameters:
    s - A String data type.
  - AttributeValue
```
public AttributeValue(List<String> sS)
```
    Constructs a new AttributeValue object. Callers should use the setter or fluent setter (with...) methods to initialize any additional object members.
    
    Parameters:
    sS - A String Set data type.
- Method Detail
  - setS
```
public void setS(String s)
```
    A String data type.
    
    Parameters:
    s - A String data type.
  - getS
```
public String getS()
```
    A String data type.
    
    Returns:
    A String data type.
  - withS
```
public AttributeValue withS(String s)
```
    A String data type.
    
    Parameters:
    s - A String data type.
    
    Returns:
    Returns a reference to this object so that method calls can be chained together.
  - setN
```
public void setN(String n)
```
    A Number data type.
    
    Parameters:
    n - A Number data type.
  - getN
```
public String getN()
```
    A Number data type.
    
    Returns:
    A Number data type.
  - withN
```
public AttributeValue withN(String n)
```
    A Number data type.
    
    Parameters:
    n - A Number data type.
    
    Returns:
    Returns a reference to this object so that method calls can be chained together.
  - setB
```
public void setB(ByteBuffer b)
```
    A Binary data type.
    
    Parameters:
    b - A Binary data type.
  - getB
```
public ByteBuffer getB()
```
    A Binary data type.
    
    ByteBuffers are stateful. Calling their get methods changes their position. We recommend using ByteBuffer.asReadOnlyBuffer() to create a read-only view of the buffer with an independent position, and calling get methods on this rather than directly on the returned ByteBuffer. Doing so will ensure that anyone else using the ByteBuffer will not be affected by changes to the position .
    
    Returns:
    A Binary data type.
