Class INDeleteInfo

java.lang.Object

com.sleepycat.je.tree.dupConvert.INDeleteInfo

All Implemented Interfaces:

Loggable

public class INDeleteInfo
extends java.lang.Object
implements Loggable

INDeleteInfo encapsulates the information logged about the removal of a child from an IN during IN compression. As of JE 3.3.87, INDelete is no longer logged becaue the root compression feature has been removed. However, INDelete must still be processed in log files created with 3.3.87 and earlier. [#17546] Obsolete in log version 8, only used by DupConvert and some log readers.
