All Implemented Interfaces:

FHIRRestInteractionVisitor
```
public class FHIRRestInteractionVisitorMeta
extends FHIRRestInteractionVisitorBase
```
Used to prepare bundle entries before they hit the persistence layer. For write operations (CREATE, UPDATE, PATCH), the meta phase is responsible for establishing the identity of any incoming resource, and updating the meta element accordingly. For other operations it is currently a NOP, but in the future may be used for optimistic async reads when the payload has been offloaded to another system.
