public class AkubraLowlevelStorageModule extends Module implements ILowlevelStorage, IListable, ISizable, ICheckable
AkubraLowlevelStore instance as a
Module.
To use this module, edit $FEDORA_HOME/config/akubra-llstore.xml
as appropriate and replace the existing LowlevelStorage
module in fedora.fcfg with the following:
<module role="org.fcrepo.server.storage.lowlevel.ILowlevelStorage" class="org.fcrepo.server.storage.lowlevel.akubra.AkubraLowlevelStorageModule"/>
