All Implemented Interfaces:

LogEntry, NodeLogEntry, java.lang.Cloneable

public class DeletedDupLNLogEntry
extends LNLogEntry

DupDeletedLNEntry encapsulates a deleted dupe LN entry. This contains all the regular transactional LN log entry fields and an extra key, which is the nulled out data field of the LN (which becomes the key in the duplicate tree.
