Package org.alfresco.filesys.repo

Class OpenOfficeContentNetworkFile

  • All Implemented Interfaces:
    NetworkFileLegacyReferenceCount, org.alfresco.jlan.server.filesys.cache.NetworkFileStateInterface
    public class OpenOfficeContentNetworkFile
extends ContentNetworkFile
    OpenOffice Content Network File Class

    Provides special handling for OpenOffice file saves that open the file, truncate, close, then open the file again to write the data, as this causes multiple versions to be generated when the file is versionable.
