Method Details

onPrepare

protected abstract void onPrepare(IVirtualFile importedFile,
 boolean integrity)
                           throws IOException

Throws:

IOException

getMinimumPartSize

protected abstract long getMinimumPartSize(IVirtualFile file)
                                    throws IOException

Throws:

IOException

initialize

public void initialize(int bufferSize,
 int threads)

Constructs a file importer that can be used to import files to the drive

Parameters:

bufferSize - Buffer size to be used when encrypting files. If using integrity this value has to be a multiple of the Chunk size. If not using integrity it should be a multiple of the AES block size for better performance

threads - The threads to use for import

stop

public void stop()

Stops all current importing tasks

isRunning

public boolean isRunning()

True if importer is currently running a job.

Returns:

True if running

importFile

public IVirtualFile importFile(IRealFile fileToImport,
 IVirtualFile dir,
 String filename,
 boolean deleteSource,
 boolean integrity,
 BiConsumer<Long,Long> onProgress)
                        throws Exception

Imports a real file into the drive.

Parameters:

fileToImport - The source file that will be imported in to the drive.

dir - The target directory in the drive that the file will be imported

filename - The filename to use

deleteSource - If true delete the source file.

integrity - Apply data integrity

onProgress - Progress to notify

Returns:

The imported file

Throws:

Exception - Thrown if error occurs during import

finalize

protected void finalize()

Overrides:

finalize in class Object

close

public void close()
