org.apache.hadoop.hdfs.inotify.EventBatchList

@Private
public class EventBatchList
extends java.lang.Object

Contains a list of event batches, the transaction ID in the edit log up to which we read to produce these events, and the first txid we observed when producing these events (the last of which is for the purpose of determining whether we have missed events due to edit deletion). Also contains the most recent txid that the NameNode has sync'ed, so the client can determine how far behind in the edit log it is.
