Class MySQLEventId

java.lang.Object
  com.continuent.tungsten.replicator.database.MySQLEventId

All Implemented Interfaces:

EventId, java.lang.Comparable<EventId>

public class MySQLEventId
extends java.lang.Object
implements EventId

Implements a MySQL event ID, which have the following form:

[prefix-name.]file_index:offset[;session_id]

For example, a MySQL event ID formatted by Tungsten would typically appear as follows:

mysql-bin.014371:0000000064207416;0

This class will correctly match and sort that event ID against events having the following formats:

mysql-bin.014371:64207416

014371:64207416
