Package oracle.kv
Class ReturnValueVersion
java.lang.Object
oracle.kv.ValueVersion
oracle.kv.ReturnValueVersion
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 as KVStore.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.
