transferInitiated

public void transferInitiated(TransferEvent event)
                       throws TransferCancelledException

Description copied from interface: TransferListener

Notifies the listener about the initiation of a transfer. This event gets fired before any actual network access to the remote repository and usually indicates some thread is now about to perform the transfer. For a given transfer request, this event is the first one being fired and it must be emitted exactly once.

Specified by:

transferInitiated in interface TransferListener

Overrides:

transferInitiated in class AbstractTransferListener

Parameters:

event - The event details, must not be null.

Throws:

TransferCancelledException - If the transfer should be aborted.

transferStarted

public void transferStarted(TransferEvent event)
                     throws TransferCancelledException

Description copied from interface: TransferListener

Notifies the listener about the start of a data transfer. This event indicates a successful connection to the remote repository. In case of a download, the requested remote resource exists and its size is given by TransferResource.getContentLength() if possible. This event may be fired multiple times for given transfer request if said transfer needs to be repeated (e.g. in response to an authentication challenge).

Specified by:

transferStarted in interface TransferListener

Overrides:

transferStarted in class AbstractTransferListener

Parameters:

event - The event details, must not be null.

Throws:

TransferCancelledException - If the transfer should be aborted.

transferProgressed

public void transferProgressed(TransferEvent event)
                        throws TransferCancelledException

Description copied from interface: TransferListener

Notifies the listener about some progress in the data transfer. This event may even be fired if actually zero bytes have been transferred since the last event, for instance to enable cancellation.

Specified by:

transferProgressed in interface TransferListener

Overrides:

transferProgressed in class AbstractTransferListener

Parameters:

event - The event details, must not be null.

Throws:

TransferCancelledException - If the transfer should be aborted.

transferCorrupted

public void transferCorrupted(TransferEvent event)
                       throws TransferCancelledException

Description copied from interface: TransferListener

Notifies the listener that a checksum validation failed. TransferEvent.getException() will be of type ChecksumFailureException and can be used to query further details about the expected/actual checksums.

Specified by:

transferCorrupted in interface TransferListener

Overrides:

transferCorrupted in class AbstractTransferListener

Parameters:

event - The event details, must not be null.

Throws:

TransferCancelledException - If the transfer should be aborted.

transferSucceeded

public void transferSucceeded(TransferEvent event)

Description copied from interface: TransferListener

Notifies the listener about the successful completion of a transfer. This event must be fired exactly once for a given transfer request unless said request failed.

Specified by:

transferSucceeded in interface TransferListener

Overrides:

transferSucceeded in class AbstractTransferListener

Parameters:

event - The event details, must not be null.

transferFailed

public void transferFailed(TransferEvent event)

Description copied from interface: TransferListener

Notifies the listener about the unsuccessful termination of a transfer. TransferEvent.getException() will provide further information about the failure.

Specified by:

transferFailed in interface TransferListener

Overrides:

transferFailed in class AbstractTransferListener

Parameters:

event - The event details, must not be null.
