dS )r a^ A base class for exporting your own Named Services across the Bus.
When instantiated, objects of this class attempt to claim the given
well-known name on the given bus for the current process. The name is
released when the BusName object becomes unreferenced.
If a well-known name is requested multiple times, multiple references
to the same BusName object will be returned.
Caveats
-------
- Assumes that named services are only ever requested using this class -
if you request names from the bus directly, confusion may occur.
- Does not handle queueing.

aS Constructor, which may either return an existing cached object
or a new object.
:Parameters:
`name` : str
The well-known name to be advertised
`bus` : dbus.Bus
A Bus on which this service will be advertised.
Omitting this parameter or setting it to None has been
deprecated since version 0.82.1. For backwards compatibility,
if this is done, the global shared connection to the session
bus will be used.
`allow_replacement` : bool
If True, other processes trying to claim the same well-known
name will take precedence over this one.
`replace_existing` : bool
If True, this process can take over the well-known name
from other processes already holding it.
`do_not_queue` : bool
If True, this service will not be placed in the queue of
services waiting for the requested name if another service
already holds it.

Just inherit from Object and mark exported methods with the
@\ `dbus.service.method` or @\ `dbus.service.signal` decorator.
Example::
class Example(dbus.service.object):
def __init__(self, object_path):
dbus.service.Object.__init__(self, dbus.SessionBus(), path)
self._last_input = None
@dbus.service.method(interface='com.example.Sample',
in_signature='v', out_signature='s')
def StringifyVariant(self, var):
self.LastInputChanged(var) # emits the signal
return str(var)
@dbus.service.signal(interface='com.example.Sample',
signature='v')
def LastInputChanged(self, var):
# run just before the signal is actually emitted
# just put "pass" if nothing should happen
self._last_input = var
@dbus.service.method(interface='com.example.Sample',
in_signature='', out_signature='v')
def GetLastInput(self):
return self._last_input

||� dS )a Constructor. Either conn or bus_name is required; object_path
is also required.
:Parameters:
`conn` : dbus.connection.Connection or None
The connection on which to export this object.
If None, use the Bus associated with the given ``bus_name``.
If there is no ``bus_name`` either, the object is not
initially available on any Connection.
For backwards compatibility, if an instance of
dbus.service.BusName is passed as the first parameter,
this is equivalent to passing its associated Bus as
``conn``, and passing the BusName itself as ``bus_name``.
`object_path` : str or None
A D-Bus object path at which to make this Object available
immediately. If this is not None, a `conn` or `bus_name` must
also be provided.
`bus_name` : dbus.service.BusName or None
Represents a well-known name claimed by this process. A
reference to the BusName object will be held by this
Object, preventing the name from being released during this
Object's lifetime (unless it's released manually).

:Parameters:
`connection` : dbus.connection.Connection
Export the object on this connection. If the class attribute
SUPPORTS_MULTIPLE_CONNECTIONS is False (default), this object
can only be made available on one connection; if the class
attribute is set True by a subclass, the object can be made
available on more than one connection.
`path` : dbus.ObjectPath or other str
Place the object at this object path. If the class attribute
SUPPORTS_MULTIPLE_OBJECT_PATHS is False (default), this object
can only be made available at one object path; if the class
attribute is set True by a subclass, the object can be made
available with more than one object path.
:Raises ValueError: if the object's class attributes do not allow the
object to be exported in the desired way.

remove from all Connections on which it's exported.
