Class FreeClassObjectAction

java.lang.Object

oracle.ifs.admin.tools.upgrade.actions.AbstractUpgradeAction

oracle.ifs.admin.tools.upgrade.actions.LibrarySessionAction

oracle.ifs.admin.tools.upgrade.actions.FreeClassObjectAction

All Implemented Interfaces:

UpgradeAction

public class FreeClassObjectAction
extends LibrarySessionAction

Frees a classobject, after optionally freeing all its instances.

The classobject to be removed is specified by a property. As a result, upgrade actions can often use this class as is, without needing to add an action-specific subclass.
