class RemoteReference(Serializable, styles.Ephemeral): (source)
Known subclasses: twisted.words.service.AvatarReference
, twisted.words.service.PBGroupReference
, twisted.words.service.PBMindReference
Constructor: RemoteReference(perspective, broker, luid, doRefCount)
Implements interfaces: twisted.spread.interfaces.IUnjellyable
A translucent reference to a remote object.
I may be a reference to a flavors.ViewPoint
, a flavors.Referenceable
, or an IPerspective
implementer (e.g., pb.Avatar). From the client's perspective, it is not possible to tell which except by convention.
I am a "translucent" reference because although no additional bookkeeping overhead is given to the application programmer for manipulating a reference, return values are asynchronous.

(internal) Initialize me with a broker and a locally-unique ID.
The ID is unique only to the particular Perspective Broker instance.
Asynchronously invoke a remote method.
Parameters | |
_name:str | the name of the remote method to invoke |
*args | arguments to serialize for the remote function |
**kw | keyword arguments to serialize for the remote function. |
Returns | |
twisted.internet.defer.Deferred | a Deferred which will be fired when the result of this remote call is received. |
twisted.spread.pb.Jellyable.jellyFor
If I am being sent back to where I came from, serialize as a local backreference.
Register a callback to be called if our broker gets disconnected.
Parameters | |
callback | a callable which will be called with one argument, this instance. |
twisted.words.service.PBGroupReference

Parameters | |
unjellier | Undocumented |
unjelly | Undocumented |
jellier | A stateful object which exists for the lifetime of a single call to unjelly . |
jelly | The list which represents the jellied state of the object to be unjellied. |
Returns | |
The object which results from unjellying. |
