public DefaultFileTransferManager()

Default constructor creates the cache.

Method Detail

isMatchProxyTransfer

public boolean isMatchProxyTransfer()

Returns true if the proxy transfer should be matched to an existing file transfer in the system.

Returns:

Returns true if the proxy transfer should be matched to an existing file transfer in the system.

cacheFileTransfer

protected void cacheFileTransfer(String key,
                                 FileTransfer transfer)

retrieveFileTransfer

protected FileTransfer retrieveFileTransfer(String key)

getChildElement

protected static org.dom4j.Element getChildElement(org.dom4j.Element element,
                                                   String namespace)

acceptIncomingFileTransferRequest

public boolean acceptIncomingFileTransferRequest(FileTransfer transfer)
                                          throws FileTransferRejectedException

Description copied from interface: FileTransferManager

Checks an incoming file transfer request to see if it should be accepted or rejected. If it is accepted true will be returned and if it is rejected false will be returned.

Specified by:

acceptIncomingFileTransferRequest in interface FileTransferManager

Parameters:

transfer - the transfer to test for acceptance

Returns:

true if it should be accepted false if it should not.

Throws:

FileTransferRejectedException - if the request was rejected (can this ever happen?)

registerProxyTransfer

public void registerProxyTransfer(String transferDigest,
                                  ProxyTransfer proxyTransfer)
                           throws UnauthorizedException

Description copied from interface: FileTransferManager

Registers that a transfer has begun through the proxy connected to the server.

Specified by:

registerProxyTransfer in interface FileTransferManager

Parameters:

transferDigest - the digest of the initiator + target + sessionID that uniquely identifies a file transfer

proxyTransfer - the related proxy transfer.

Throws:

UnauthorizedException - when in the current server configuration this transfer should not be permitted.

addListener

public void addListener(FileTransferEventListener eventListener)

Description copied from interface: FileTransferManager

Registers an event listener that will be notified of file transfer related events.

Specified by:

addListener in interface FileTransferManager

Parameters:

eventListener - an event listener (cannot be null).

removeListener

public void removeListener(FileTransferEventListener eventListener)

Description copied from interface: FileTransferManager

Unregisters an event listener from the list of event listeners that are notified of file transfer related events.

Specified by:

removeListener in interface FileTransferManager

Parameters:

eventListener - an event listener (cannot be null).

fireFileTransferStart

public void fireFileTransferStart(String sid,
                                  boolean isReady)
                           throws FileTransferRejectedException

Description copied from interface: FileTransferManager

Invokes FileTransferEventListener.fileTransferStart(FileTransfer, boolean) for all registered event listeners.

Specified by:

fireFileTransferStart in interface FileTransferManager

Parameters:

sid - The session id of the file transfer that is being intercepted (cannot be null).

isReady - true if the transfer is ready to commence or false if this is related to the initial file transfer request. An exception at this point will cause the transfer to not go through.

Throws:

FileTransferRejectedException - When at least one of the listeners aborts the file transfer.

fireFileTransferCompleted

public void fireFileTransferCompleted(String sid,
                                      boolean wasSuccessful)

Description copied from interface: FileTransferManager

Invokes FileTransferEventListener.fileTransferComplete(FileTransfer, boolean) for all registered event listeners.

Specified by:

fireFileTransferCompleted in interface FileTransferManager

Parameters:

sid - The session id of the file transfer that is being intercepted (cannot be null).

wasSuccessful - false when an exception was thrown during file transfer, otherwise true.
