connectionReady(self)Initialize. Called after Banana negotiation is done.
|
decCacheRef(self, objectID)(internal) Send a DECACHE directive. |
dontNotifyOnDisconnect(self, notifier)Remove a callback from list of disconnect callbacks. |
expressionReceived(self, sexp)Evaluate an expression as it's received. |
localObjectForID(self, luid)Get a local object for a locally unique ID. I will return an object previously stored with self.registerReference , or None
if XXX:Unfinished thought:XXX
|
newLocalID(self)Generate a new LUID. |
newRequestID(self)Generate a new request ID. |
notifyOnConnect(self, notifier)Call the given callback when the Broker connects. |
notifyOnDisconnect(self, notifier)Call the given callback when the Broker disconnects. |
notifyOnFail(self, notifier)Call the given callback if the Broker fails to connect. |
proto_answer(self, requestID, netResult)(internal) Got an answer to a previously sent message. Look up the appropriate callback and call it. |
proto_decache(self, objectID)(internal) Decrement the reference count of a cached object. If the reference count is zero, free the reference, then send an 'uncached' directive. |
proto_decref(self, objectID)(internal) Decrement the reference count of an object. If the reference count is zero, it will free the reference to this object. |

proto_uncache(self, objectID)(internal) Tell the client it is now OK to uncache an object. |
proto_version(self, vnum)Protocol message: (version version-number) Check to make sure that both ends of the protocol are speaking the same version dialect. |
registerReference(self, object)Get an ID for a local object. Store a persistent reference to a local object and map its id() to a generated, session-unique ID and return that ID. |
remoteForName(self, name)Returns an object from the remote name mapping. Note that this does not check the validity of the name, only creates a translucent reference for it. |
remotelyCachedForLUID(self, luid)Returns an instance which is cached remotely, with this LUID. |
resumeProducing(self)Called when the consumer attached to me runs out of buffer. |
sendCall(self, *exp)Utility method to send an expression to the other side of the connection. |
