Constructor Detail

AttributeValue

public AttributeValue()

Default constructor for DynamodbAttributeValue 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 DynamodbAttributeValue object. Callers should use the setter or fluent setter (with...) methods to initialize any additional object members.

Parameters:

s - An attribute of type String. For example:

"S": "Hello"

AttributeValue

public AttributeValue(List<String> sS)

Constructs a new DynamodbAttributeValue object. Callers should use the setter or fluent setter (with...) methods to initialize any additional object members.

Parameters:

sS - An attribute of type String Set. For example:

"SS": ["Giraffe", "Hippo" ,"Zebra"]

Method Detail

setS

setN

public void setN(String n)

An attribute of type Number. For example:

"N": "123.45"

Numbers are sent across the network to DynamoDB as strings, to maximize compatibility across languages and libraries. However, DynamoDB treats them as number type attributes for mathematical operations.

Parameters:

n - An attribute of type Number. For example:

"N": "123.45"

Numbers are sent across the network to DynamoDB as strings, to maximize compatibility across languages and libraries. However, DynamoDB treats them as number type attributes for mathematical operations.

getN

public String getN()

An attribute of type Number. For example:

"N": "123.45"

Numbers are sent across the network to DynamoDB as strings, to maximize compatibility across languages and libraries. However, DynamoDB treats them as number type attributes for mathematical operations.

Returns:

An attribute of type Number. For example:

"N": "123.45"

Numbers are sent across the network to DynamoDB as strings, to maximize compatibility across languages and libraries. However, DynamoDB treats them as number type attributes for mathematical operations.

withN

public AttributeValue withN(String n)

An attribute of type Number. For example:

"N": "123.45"

Numbers are sent across the network to DynamoDB as strings, to maximize compatibility across languages and libraries. However, DynamoDB treats them as number type attributes for mathematical operations.

Parameters:

n - An attribute of type Number. For example:

"N": "123.45"

Numbers are sent across the network to DynamoDB as strings, to maximize compatibility across languages and libraries. However, DynamoDB treats them as number type attributes for mathematical operations.

setB

public void setB(ByteBuffer b)

An attribute of type Binary. For example:

"B": "dGhpcyB0ZXh0IGlzIGJhc2U2NC1lbmNvZGVk"

The AWS SDK for Java performs a Base64 encoding on this field before sending this request to the AWS service. Users of the SDK should not perform Base64 encoding on this field.

Warning: ByteBuffers returned by the SDK are mutable. Changes to the content or position of the byte buffer will be seen by all objects that have a reference to this object. It is recommended to call ByteBuffer.duplicate() or ByteBuffer.asReadOnlyBuffer() before using or reading from the buffer. This behavior will be changed in a future major version of the SDK.

Parameters:

b - An attribute of type Binary. For example:

"B": "dGhpcyB0ZXh0IGlzIGJhc2U2NC1lbmNvZGVk"

getB

public ByteBuffer getB()

An attribute of type Binary. For example:

"B": "dGhpcyB0ZXh0IGlzIGJhc2U2NC1lbmNvZGVk"

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:

An attribute of type Binary. For example:

"B": "dGhpcyB0ZXh0IGlzIGJhc2U2NC1lbmNvZGVk"

withB

public AttributeValue withB(ByteBuffer b)

An attribute of type Binary. For example:

"B": "dGhpcyB0ZXh0IGlzIGJhc2U2NC1lbmNvZGVk"

The AWS SDK for Java performs a Base64 encoding on this field before sending this request to the AWS service. Users of the SDK should not perform Base64 encoding on this field.

Warning: ByteBuffers returned by the SDK are mutable. Changes to the content or position of the byte buffer will be seen by all objects that have a reference to this object. It is recommended to call ByteBuffer.duplicate() or ByteBuffer.asReadOnlyBuffer() before using or reading from the buffer. This behavior will be changed in a future major version of the SDK.

Parameters:

b - An attribute of type Binary. For example:

"B": "dGhpcyB0ZXh0IGlzIGJhc2U2NC1lbmNvZGVk"

Returns:

Returns a reference to this object so that method calls can be chained together.
