public class ReturnValueVersion extends ValueVersion
Used with put and delete operations to return the previous value and version.A ReturnValueVersion instance may be created and passed as the
prevValue
parameter to methods such asKVStore.put(Key, Value, ReturnValueVersion, Durability, long, TimeUnit)
.For best performance, it is important to choose only the properties that are required. The KV Store is optimized to avoid I/O when the requested properties are in cache.
Note that because both properties are optional, the version property, value property, or both properties may be null.
