Overrides: object.__init__

to_xml(self)

source code 

convert representation into XML representation. Currently cannot represent private parameters. :returns:: XML representation for remote machine, ``str``

to_remote_xml(self)

source code 

convert representation into remote representation. Remote representation does not include parameter settings or 'machine' attribute :returns:: XML representation for remote machine, ``str``
