FlatFileBufferLinkedList (Jackrabbit Oak 1.62.0 API)

java.lang.Object
- org.apache.jackrabbit.oak.index.indexer.document.flatfile.linkedList.FlatFileBufferLinkedList

All Implemented Interfaces:

NodeStateEntryList
```
public class FlatFileBufferLinkedList
extends java.lang.Object
implements NodeStateEntryList
```
Linked list implementation which supports multiple iterators. The iterator's state is backed by an actual node in the list. So, modification in the list show up in iterator (assuming thread safely/volatility) getting handled outside of the class.
