Method Detail

newFileChannel

public FileChannel newFileChannel(EffectiveOpenOptions options)
                           throws IOException

Creates a new file channel with the given open options.

Parameters:

options - The options to use to open the file channel. For the most part these will be passed through to the ciphertext channel.

Returns:

A new file channel. Ideally used in a try-with-resource statement. If the channel is not properly closed, this OpenCryptoFile will stay open indefinite.

Throws:

IOException

size

public Optional<Long> size()

Returns:

The size of the opened file. Note that the filesize is unknown until a file channel is opened. In this case this method returns an empty optional.

getLastModifiedTime

public FileTime getLastModifiedTime()

setLastModifiedTime

public void setLastModifiedTime(FileTime lastModifiedTime)

getCurrentFilePath

public Path getCurrentFilePath()

setCurrentFilePath

public void setCurrentFilePath(Path currentFilePath)
