Method getStateToCacheAndObserveFor Get state to cache on the client and client-cache reference to observe locally.

Inherited from Cacheable:

Method jellyFor Return an appropriate tuple to serialize me.
Method stoppedObserving This method is called when a client has stopped observing me.

Inherited from Copyable (via Cacheable):

Method getStateToCopy Gather state to send when I am serialized for a peer.
Method getStateToCopyFor Gather state to send when I am serialized for a particular perspective.
Method getTypeToCopy Determine what type tag to send for me.
Method getTypeToCopyFor Determine what type tag to send for me.

Inherited from RemoteCache (via Cacheable, Copyable):

Method __cmp__ Compare me [to another RemoteCache.
Method __del__ Do distributed reference counting on finalize.
Method __hash__ Hash me.
Method remoteMessageReceived A remote message has been received. Dispatch it appropriately.
Method unjellyFor Perform the inverse operation of Jellyable.jellyFor.
Instance Variable __dict__ Undocumented
Instance Variable broker Undocumented
Instance Variable luid Undocumented
Method _borgify Create a new object that shares its state (i.e. its __dict__) and type with this object, but does not share its identity.

Inherited from RemoteCopy (via Cacheable, Copyable, RemoteCache):

Method setCopyableState I will be invoked with the state to copy locally.

Inherited from Unjellyable (via Cacheable, Copyable, RemoteCache, RemoteCopy):

Method setStateFor Undocumented

Inherited from Serializable (via Cacheable, Copyable, RemoteCache, RemoteCopy, Unjellyable):

Method processUniqueID Return an ID which uniquely represents this object for this process.

Method getStateFor Undocumented
def getStateToCacheAndObserveFor(self, perspective, observer): (source)
overrides twisted.spread.pb.Cacheable.getStateToCacheAndObserveFor

Get state to cache on the client and client-cache reference to observe locally.

This is similar to getStateToCopyFor, but it additionally passes in a reference to the client-side RemoteCache instance that will be created when it is unserialized. This allows Cacheable instances to keep their RemoteCaches up to date when they change, such that no changes can occur between the point at which the state is initially copied and the client receives it that are not propagated.
