Class FlatFileBufferLinkedList

java.lang.Object

org.apache.jackrabbit.oak.index.indexer.document.flatfile.linkedList.FlatFileBufferLinkedList

All Implemented Interfaces:

NodeStateEntryList

public class FlatFileBufferLinkedList
extends 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.
