addFile

public void addFile(UploadRequestRecord urr)
             throws NFMSException

Description copied from interface: NMDSAdapter

Creates a new file entry from the upload request, setting permissions as needed or versioning if so required by the request. This also sets the physical location.

Specified by:

addFile in interface NMDSAdapter

Throws:

NFMSException

deleteFile

public void deleteFile(LogicalName logicalName,
                       int version)
                throws NFMSException

Description copied from interface: NMDSAdapter

Deletes the specified version of the file. No exception is thrown if the stated version does not exist. All this does is mark it as deleted if there is such a version.

Specified by:

Throws:

NFMSException

getLatestVersionNumber

public int getLatestVersionNumber(LogicalName logicalName)
                           throws NFMSException

Description copied from interface: NMDSAdapter

Ask the repository what the most recent version of this file is that is available. The very first version is indexed starting at zero. If there is no available entry, then the value of NFMSConstants.FILE_VERSION_UNAVAILABLE is returned. Note that this version will be the latest, if that is not marked as unavailable.

Specified by:

getLatestVersionNumber in interface NMDSAdapter

Throws:

NFMSException
