All Implemented Interfaces:

Action, IfsParameters

public class FreeClassObjectAction
extends LibrarySessionUpgradeAction

Frees a ClassObject.

Instead of using this class, new upgrade actions should use FreeClassObjectAction, which is more data driven (often eliminating the need for a subclass) and supports online upgrade.
