Method Details

getScpFileOpener

public ScpFileOpener getScpFileOpener()

Specified by:

getScpFileOpener in interface ScpFileOpenerHolder

Returns:

The last ScpFileOpener set via call to ScpFileOpenerHolder.setScpFileOpener(ScpFileOpener)

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

getSendBufferSize

public int getSendBufferSize()

setSendBufferSize

public void setSendBufferSize(int sendSize)

Parameters:

sendSize - Size (in bytes) of buffer to use when sending files

See Also:

• ScpHelper.MIN_SEND_BUFFER_SIZE

getReceiveBufferSize

public int getReceiveBufferSize()

setReceiveBufferSize

public void setReceiveBufferSize(int receiveSize)

Parameters:

See Also:

• ScpHelper.MIN_RECEIVE_BUFFER_SIZE

addEventListener

public boolean addEventListener(ScpTransferEventListener listener)

Parameters:

listener - The ScpTransferEventListener to add

Returns:

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:
