setScpFileOpener

public void setScpFileOpener(ScpFileOpener fileOpener)

Specified by:

setScpFileOpener in interface ScpFileOpenerHolder

Parameters:

fileOpener - The default ScpFileOpener to use - if null then a default opener is used

See Also:

ScpHelper.MIN_RECEIVE_BUFFER_SIZE

addEventListener

public boolean addEventListener(ScpTransferEventListener listener)

Parameters:

listener - The ScpTransferEventListener to add

true if this is a new listener instance, false if the listener is already registered

Throws:

IllegalArgumentException - if null listener

removeEventListener

public boolean removeEventListener(ScpTransferEventListener listener)

Parameters:

listener - The ScpTransferEventListener to remove

Returns:

true if the listener was registered and removed, false if the listener was not registered to begin with

Throws:

IllegalArgumentException - if null listener

isSupportedCommand

public boolean isSupportedCommand(ChannelSession channel,
                                  String command)

Specified by:

isSupportedCommand in class AbstractDelegatingCommandFactory

executeSupportedCommand

protected Command executeSupportedCommand(ChannelSession channel,
                                          String command)

Specified by:

executeSupportedCommand in class AbstractDelegatingCommandFactory

getDelegateShellFactory

public ShellFactory getDelegateShellFactory()

Returns:
