ReconnectingPBClientFactory
Reconnecting client factory for PB brokers.
Like PBClientFactory, but if the connection fails or is lost, the
factory will attempt to reconnect.
Instead of using f.getRootObject (which gives a Deferred that can only
be fired once), override the gotRootObject method.
Instead of using the newcred f.login (which is also one-shot), call
f.startLogin() with the credentials and client, and override the
gotPerspective method.
Instead of using the oldcred f.getPerspective (also one-shot), call
f.startGettingPerspective() with the same arguments, and override
gotPerspective.
gotRootObject and gotPerspective will be called each time the object
is received (once per successful connection attempt). You will probably
want to use obj.notifyOnDisconnect to find out when the connection is
lost.
If an authorization error occurs, failedToGetPerspective() will be
invoked.
To use me, subclass, then hand an instance to a connector (like
TCPClient).

gotPerspective(self,
perspective)
The remote avatar or perspective (obtained each time this factory
connects) is now available. |

The remote root object (obtained each time this factory connects)
is now available. |

failedToGetPerspective(self,
why)
The login process failed, most likely because of an authorization
failure (bad password), but it is also possible that we lost the new
connection before we managed to send our credentials. |

Login and get perspective from remote PB server.
Currently only credentials implementing twisted.cred.credentials.IUsernamePassword are
supported.
- Returns:
- Deferred of RemoteReference to the perspective.

The remote root object (obtained each time this factory connects) is
now available. This method will be called each time the connection is
established and the object reference is retrieved.
