Class MessageAttributeValue

java.lang.Object

com.amazonaws.services.sns.model.MessageAttributeValue

All Implemented Interfaces:

Serializable, Cloneable

public class MessageAttributeValue
extends Object
implements Serializable, Cloneable

The user-specified message attribute value. For string data types, the value attribute has the same restrictions on the content as the message body. For more information, see Publish.

Name, type, and value must not be empty or null. In addition, the message body should not be empty or null. All parts of the message attribute, including name, type, and value, are included in the message size restriction, which is currently 256 KB (262,144 bytes). For more information, see Using Amazon SNS Message Attributes.

Parameters:

dataType - Amazon SNS supports the following logical data types: String, Number, and Binary. For more information, see Message Attribute Data Types.

Returns:

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

setStringValue

public void setStringValue(String stringValue)

Strings are Unicode with UTF8 binary encoding. For a list of code values, see http://en.wikipedia.org/wiki/ASCII#ASCII_printable_characters.

Parameters:

stringValue - Strings are Unicode with UTF8 binary encoding. For a list of code values, see http ://en.wikipedia.org/wiki/ASCII#ASCII_printable_characters.

getStringValue

public String getStringValue()

Strings are Unicode with UTF8 binary encoding. For a list of code values, see http://en.wikipedia.org/wiki/ASCII#ASCII_printable_characters.

Returns:

Strings are Unicode with UTF8 binary encoding. For a list of code values, see http ://en.wikipedia.org/wiki/ASCII#ASCII_printable_characters.

withStringValue

public MessageAttributeValue withStringValue(String stringValue)

Strings are Unicode with UTF8 binary encoding. For a list of code values, see http://en.wikipedia.org/wiki/ASCII#ASCII_printable_characters.

Parameters:

stringValue - Strings are Unicode with UTF8 binary encoding. For a list of code values, see http ://en.wikipedia.org/wiki/ASCII#ASCII_printable_characters.

Returns:

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

setBinaryValue

public void setBinaryValue(ByteBuffer binaryValue)

Binary type attributes can store any binary data, for example, compressed data, encrypted data, or images.

AWS SDK for Java performs a Base64 encoding on this field before sending this request to AWS service by default. 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:

binaryValue - Binary type attributes can store any binary data, for example, compressed data, encrypted data, or images.

getBinaryValue

public ByteBuffer getBinaryValue()

Binary type attributes can store any binary data, for example, compressed data, encrypted data, or images.

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:

Binary type attributes can store any binary data, for example, compressed data, encrypted data, or images.

withBinaryValue

public MessageAttributeValue withBinaryValue(ByteBuffer binaryValue)

Binary type attributes can store any binary data, for example, compressed data, encrypted data, or images.

Parameters:

binaryValue - Binary type attributes can store any binary data, for example, compressed data, encrypted data, or images.

Returns:

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

public String toString()

Returns a string representation of this object; useful for testing and debugging.

Overrides:

toString in class Object

Returns:

A string representation of this object.
