XMPP XML Stream protocol handler.

Method __init__ Undocumented
Method connectionMade Called when a connection is made.
Method onDocumentStart Called when the stream header has been received.
Method onStreamError Called when a stream:error element has been received.
Method reset Reset XML Stream.
Method send Send data over the stream.
Method sendFooter Send stream footer.
Method sendHeader Send stream header.
Method sendStreamError Send stream level error.
Instance Variable authenticator associated authenticator that uses initializers to initialize the XML stream.
Instance Variable features map of (uri, name) to stream features element received from the receiving entity.
Instance Variable initializers list of stream initializer objects
Instance Variable initiating True if this is the initiating stream
Instance Variable namespace default namespace URI for stream
Instance Variable otherEntity JID of the peer entity
Instance Variable prefixes map of URI to prefixes that are to appear on stream header.
Instance Variable sid session identifier
Instance Variable thisEntity JID of this entity
Instance Variable version XML stream version as a tuple (major, minor). Initially, this is set to the minimally supported version. Upon receiving the stream header of the peer, it is set to the minimum of that value and the version on the received header.

Inherited from XmlStream:

Method connectionLost Called when the connection is shut down.
Method dataReceived Called whenever data is received.
Method onDocumentEnd Called whenever the end tag of the root element has been received.
Method onElement Called whenever a direct child element of the root element has been received.
Method resetDispatchFn Set the default function (onElement) to handle elements.
Method setDispatchFn Set another function to handle elements.
Instance Variable rawDataInFn Undocumented

Method _initializeStream Sets up XML Parser.

Inherited from Protocol (via XmlStream):

Method logPrefix Return a prefix matching the class name, to identify log messages related to this protocol instance.
Class Variable factory Undocumented

Inherited from BaseProtocol (via XmlStream, Protocol):

Method makeConnection Make a connection to a transport and a server.
Instance Variable connected Undocumented
Instance Variable transport Undocumented

Inherited from EventDispatcher (via XmlStream, Protocol, BaseProtocol):

Method addObserver Register an observer for an event.
Method addOnetimeObserver Register a one-time observer for an event.
Method dispatch Dispatch an event.
Method removeObserver Remove callable as observer for an event.
Instance Variable prefix Undocumented
Method _addObserver Undocumented

Instance Variable _xpathObservers Undocumented
def __init__(self, authenticator): (source)
def connectionMade(self): (source)

Called when a connection is made.

Notifies the authenticator when a connection has been made.

def onDocumentStart(self, rootElement): (source)

Called when the stream header has been received.

Extracts the header's id and version attributes from the root element. The id attribute is stored in our sid attribute and the version attribute is parsed and the minimum of the version we sent and the parsed version attribute is stored as a tuple (major, minor) in this class' version attribute. If no version attribute was present, we assume version 0.0.

If appropriate (we are the initiating stream and the minimum of our and the other party's version is at least 1.0), a one-time observer is registered for getting the stream features. The registered function is onFeatures.

Ultimately, the authenticator's streamStarted method will be called.

Parameters
rootElement:domish.ElementThe root element.
def onStreamError(self, errelem): (source)

Called when a stream:error element has been received.

Dispatches a STREAM_ERROR_EVENT event with the error element to allow for cleanup actions and drops the connection.

Parameters
errelem:domish.ElementThe received error element.
def reset(self): (source)

Reset XML Stream.

Resets the XML Parser for incoming data. This is to be used after successfully negotiating a new layer, e.g. TLS and SASL. Note that registered event observers will continue to be in place.

def send(self, obj): (source)

Send data over the stream.

This overrides xmlstream.XmlStream.send to use the default namespace of the stream header when serializing domish.IElements. It is assumed that if you pass an object that provides domish.IElement, it represents a direct child of the stream's root element.

def sendFooter(self): (source)

Send stream footer.

def sendHeader(self): (source)

Send stream header.

def sendStreamError(self, streamError): (source)

Send stream level error.

If we are the receiving entity, and haven't sent the header yet, we sent one first.

After sending the stream error, the stream is closed and the transport connection dropped.

Parameters
streamError:error.StreamErrorstream error instance
authenticator = (source)

associated authenticator that uses initializers to initialize the XML stream.

features: dict of (unicode, unicode) to domish.Element. = (source)

map of (uri, name) to stream features element received from the receiving entity.

initializers: list of objects that provide IInitializer = (source)

list of stream initializer objects

initiating: bool = (source)

True if this is the initiating stream

namespace: unicode = (source)

default namespace URI for stream

otherEntity: JID = (source)

JID of the peer entity

prefixes: dict of unicode to unicode = (source)

map of URI to prefixes that are to appear on stream header.

sid: unicode = (source)

session identifier

thisEntity: JID = (source)

JID of this entity

version: (int, int) = (source)

XML stream version as a tuple (major, minor). Initially, this is set to the minimally supported version. Upon receiving the stream header of the peer, it is set to the minimum of that value and the version on the received header.

def _callLater(self, *args, **kwargs): (source)

_headerSent: bool = (source)
