Annotation Type DynamoDBVersionAttribute

Deprecated. These classes have been deprecated, please use the classes in the com.amazonaws.mobileconnectors namespace.

@Retention(value=RUNTIME)
@Target(value={FIELD,METHOD})
public @interface DynamoDBVersionAttribute

Annotation for marking a property as an optimistic locking version attribute. Applied to the getter method or the class field for the class's version property. If the annotation is applied directly to the class field, the corresponding getter and setter must be declared in the same class.

Only nullable, integral numeric types (e.g. Integer, Long) can be used as version properties. On a save() operation, the DynamoDBMapper will attempt to increment the version property and assert that the service's value matches the client's. New objects will be assigned a version of 1 when saved.

Note that for batchWrite, and by extension batchSave and batchDelete, no version checks are performed, as required by the AmazonDynamoDB.batchWriteItem(BatchWriteItemRequest) API.
