Class LegacyFileStateDriver

java.lang.Object

org.alfresco.filesys.repo.LegacyFileStateDriver

All Implemented Interfaces:

ExtendedDiskInterface, DeviceInterface, DiskInterface

public class LegacyFileStateDriver
extends Object
implements ExtendedDiskInterface

The Legacy file state driver is used to update JLAN's file state cache.

This class decorates an ExtendedDiskInterface with odds and ends to keep JLan happy.

In particular this implementation cannot contain any code that requires access to the alfresco repository.
