public class FTPConnection
extends AbstractStandalone
implements org.apache.commons.net.ProtocolCommandListener

Provides access to a FTP host.
If debugging is enabled, the FTP commands issued by other actors will get printed as debug output of this actor.

Valid options are:

-D <int> (property: debugLevel)
    The greater the number the more additional info the scheme may output to
    the console (0 = off).
    default: 0
    minimum: 0
 

-name <java.lang.String> (property: name)
    The name of the actor.
    default: FTPConnection
 

-annotation <adams.core.base.BaseText> (property: annotations)
    The annotations to attach to this actor.
    default:
 

-skip (property: skip)
    If set to true, transformation is skipped and the input token is just forwarded
    as it is.
 

-stop-flow-on-error (property: stopFlowOnError)
    If set to true, the flow gets stopped in case this actor encounters an error;
     useful for critical actors.
 

-host <java.lang.String> (property: host)
    The host (name/IP address) to connect to.
    default:
 

-user <java.lang.String> (property: user)
    The FTP user to use for connecting.
    default: anonymous
 

-password <adams.core.base.BasePassword> (property: password)
    The password of the FTP user to use for connecting.
    default: {}
 

-passive (property: usePassiveMode)
    If enabled, passive mode is used instead.
