DataStoreTypes.ItemDescriptor (launchdarkly-java-server-sdk 7.4.0 API)

java.lang.Object
- com.launchdarkly.sdk.server.subsystems.DataStoreTypes.ItemDescriptor

Enclosing class:

DataStoreTypes
```
public static final class DataStoreTypes.ItemDescriptor
extends java.lang.Object
```
A versioned item (or placeholder) storable in a DataStore.
This is used for data stores that directly store objects as-is, as the default in-memory store does. Items are typed as Object; the store should not know or care what the actual object is.
For any given key within a DataStoreTypes.DataKind, there can be either an existing item with a version, or a "tombstone" placeholder representing a deleted item (also with a version). Deleted item placeholders are used so that if an item is first updated with version N and then deleted with version N+1, but the SDK receives those changes out of order, version N will not overwrite the deletion.
Persistent data stores use DataStoreTypes.SerializedItemDescriptor instead.
