Method Detail

getProtocolVersion

public long getProtocolVersion()

Returns the version of the SFTP protocol that is used in this session for communicating with the SFTP server.

Returns:

the protocol version

---

getExtensionData

public byte[] getExtensionData(String type)
                        throws SftException

Returns SFTP protocol extension data that the server has sent.

Parameters:

type - the type of the data to get

Returns:

the extension data associated with the given type

Throws:

SftException

---

getLocation

public Location getLocation(String path)

Returns a Location representing the named path.

Parameters:

path - the path to access

Returns:

a Location object representing the named path accessed through this session

---

getFile

public File getFile(String path)
             throws NoSuchFileException,
                    SftException

Returns a File object representing the file at the named path.

Parameters:

path - the path to access

Returns:

a File object representing the file currently found at the named path

Throws:

NoSuchFileException - if no file exists at the named path

SftException

---

suspend

public void suspend()

Suspends the session. All currently active file operations in this session are paused until suspend() is called. If the session is already suspended, invoking this method has no effect.

---

resume

public void resume()

Resumes the session. If the session was suspended, all paused operations are now resumed. Otherwise, this method has no effect.

---

abort

public void abort()

Aborts the session. All currently active file operations are terminated and they throw an AbortedException.

---

setForceLowerCase

public void setForceLowerCase(boolean force)

---

setFileCopyPrefix

public void setFileCopyPrefix(String prefix)

---

setIncrementalChecksums

public void setIncrementalChecksums()

---

getURI

public URI getURI()

Returns the URI for this session's SFTP server. The URI is of the form "sftp://user@host".

---

isConnected

public boolean isConnected()

---

close

public void close()
           throws SftException

Releases the resources used by this object. After this method has been called, all further operations on this object will throw a IllegalStateException.

Throws:
