Class MessageAttributeValue
- All Implemented Interfaces:
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.

setBinaryValue
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
Binary type attributes can store any binary data, for example, compressed data, encrypted data, or images.
ByteBuffer
s are stateful. Calling theirget
methods changes theirposition
. We recommend usingByteBuffer.asReadOnlyBuffer()
to create a read-only view of the buffer with an independentposition
, and callingget
methods on this rather than directly on the returnedByteBuffer
. Doing so will ensure that anyone else using theByteBuffer
will not be affected by changes to theposition
.- Returns:
- Binary type attributes can store any binary data, for example, compressed data, encrypted data, or images.
-
withBinaryValue
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.
-
