com.tailf.conf.ConfCdbUpgradePath

public class ConfCdbUpgradePath
extends ConfPath

Class Representing a KeyPath path.

This is a simplified variant of ConfPath for use with CdbUpgradeSession. During a cdb upgrade, it may be necessary to migrate data from nodes that are about to be deleted. As these nodes are not present in the maapi schema, they cannot safely be represented by standard ConfPath objects. Instead use ConfCdbUpgradePath which relies only on ConfNamespace instances and thus allows deleted paths to be referenced as long as the namespace has been reinstalled.
