com.amazon.titan.diskstorage.dynamodb.model.MutateItemResult<T>

T - UpdateItemResult or UpdateItemResult

Direct Known Subclasses:

DeleteResultWrapper, UpdateResultWrapper

public abstract class MutateItemResult<T>
extends java.lang.Object

To serialize mutations on one primary key in a DynamoDB table, need to be able to handle UpdateItem and DeleteItem, as Items can be created but not deleted with an UpdateItem. This wrapper interface allows the Storage Backend to serialize on any mutation, even if it corresponds to deleting an Item.
