def __init__(self, isClient=1, security=globalSecurity): (source)
overrides twisted.spread.banana.Banana.__init__
Undocumented
def resumeProducing(self): (source)
Called when the consumer attached to me runs out of buffer.
def pauseProducing(self): (source)
Undocumented
def stopProducing(self): (source)

Undocumented
def expressionReceived(self, sexp): (source)
overrides twisted.spread.banana.Banana.expressionReceived
Evaluate an expression as it's received.
def proto_version(self, vnum): (source)

Protocol message: (version version-number)

Check to make sure that both ends of the protocol are speaking the same version dialect.
def sendCall(self, *exp): (source)
Utility method to send an expression to the other side of the connection.
def proto_didNotUnderstand(self, command): (source)

Respond to stock 'didNotUnderstand' message.

Log the command that was not understood and continue. (Note: this will probably be changed to close the connection or raise an exception in the future.)
def connectionReady(self): (source)
overrides twisted.spread.banana.Banana.connectionReady
Initialize. Called after Banana negotiation is done.
def connectionFailed(self): (source)
Undocumented
def connectionLost(self, reason): (source)
from twisted.internet.interfaces.IProtocol
overrides twisted.internet.protocol.Protocol.connectionLost
The connection was lost.
def notifyOnDisconnect(self, notifier): (source)
Call the given callback when the Broker disconnects.
def notifyOnFail(self, notifier): (source)
Call the given callback if the Broker fails to connect.
def notifyOnConnect(self, notifier): (source)
Call the given callback when the Broker connects.
def dontNotifyOnDisconnect(self, notifier): (source)

def localObjectForID(self, luid): (source)
Get a local object for a locally unique ID.
ReturnsAn object previously stored with registerReference or None if there is no object which corresponds to the given identifier.
def registerReference(self, object): (source)

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.
def setNameForLocal(self, name, object): (source)

Store a special (string) ID for this object.

This is how you specify a 'base' set of objects that the remote protocol can connect to.
def remoteForName(self, name): (source)

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.
def cachedRemotelyAs(self, instance, incref=0): (source)
Returns an ID that says what this instance is cached as remotely, or None if it's not.
def remotelyCachedForLUID(self, luid): (source)
Returns an instance which is cached remotely, with this LUID.
def cacheRemotely(self, instance): (source)
XXX
def cacheLocally(self, cid, instance): (source)

(internal)

Store a non-filled-out cached instance locally.
def cachedLocallyAs(self, cid): (source)
Undocumented
def serialize(self, object, perspective=None, method=None, args=None, kw=None): (source)
Jelly an object according to the remote security rules for this broker.
def unserialize(self, sexp, perspective=None): (source)
Unjelly an sexp according to the local security rules for this broker.
def newLocalID(self): (source)
Generate a new LUID.
def newRequestID(self): (source)

Undocumented
def _recvMessage(self, findObjMethod, requestID, objectID, message, answerRequired, netArgs, netKw): (source)

Received a message-send.

Look up message based on object, unserialize the arguments, and invoke it with args, and send an 'answer' or 'error' response.
def _sendAnswer(self, netResult, requestID): (source)
(internal) Send an answer to a previously sent message.
def proto_answer(self, requestID, netResult): (source)

(internal) Got an answer to a previously sent message.

Look up the appropriate callback and call it.
def _sendFailureOrError(self, fail, requestID): (source)
Call _sendError or _sendFailure, depending on whether fail represents an Error subclass or not.
def _sendFailure(self, fail, requestID): (source)
Log error and then send it.
def _sendError(self, fail, requestID): (source)

def proto_uncache(self, objectID): (source)
(internal) Tell the client it is now OK to uncache an object.
