I am an SSL client.

Method __init__ No summary
Instance Variable ctxFactory Undocumented
Method _connectDone This is a hook for when a connection attempt has succeeded.

Inherited from _BaseTCPClient (via Client):

Method __repr__ Undocumented
Method getHost Returns an IPv4Address or IPv6Address.
Method getPeer Returns an IPv4Address or IPv6Address.
Instance Variable addr The address that this socket will be connecting to.
Instance Variable connector The Connector which is driving this _BaseTCPClient's connection attempt.
Instance Variable createInternetSocket Subclasses must implement this as a method to create a python socket object of the appropriate address family and socket type.
Instance Variable _addressType The Twisted _IPAddress implementation for this client
Instance Variable _requiresResolution Undocumented

Inherited from BaseClient (via Client, _BaseTCPClient):

Method doConnect Initiate the outgoing connection attempt.
Instance Variable connected Undocumented
Instance Variable logstr Undocumented
Instance Variable protocol Undocumented
Instance Variable realAddress The address object that will be used for socket.connect; this address is an address tuple (the number of elements dependent upon the address family) which does not contain any names which need to be resolved.
Method _collectSocketDetails Clean up references to the socket and its file descriptor.
Method _stopReadingAndWriting Implement the POSIX-ish (i.e. twisted.internet.interfaces.IReactorFDSet) method of detaching this socket from the reactor for _BaseBaseClient.
Instance Variable _base Connection, which is the base class of this class which has all of the useful file descriptor methods. This is used by _TLSServerMixin to call the right methods to directly manipulate the transport, as is necessary for writing TLS-encrypted bytes (whereas those methods on ...

Inherited from _BaseBaseClient (via Client, _BaseTCPClient, BaseClient):

Method connectionLost Invoked by lower-level logic when it's time to clean the socket up. Depending on the state of the connection, either inform the attached Connector that the connection attempt has failed, or inform the connected ...
Method failIfNotConnected Generic method called when the attempts to connect failed. It basically cleans everything it can: call connectionFailed, stop read and write, delete socket related members.
Method resolveAddress Resolve the name that was passed to this _BaseBaseClient, if necessary, and then move on to attempting the connection once an address has been determined. (The connection will be attempted immediately within this function if either name resolution can be synchronous or the address was an IP address literal...
Method stopConnecting If a connection attempt is still outstanding (i.e. no connection is yet established), immediately stop attempting to connect.
Instance Variable addressFamily The address family constant (socket.AF_INET, socket.AF_INET6, socket.AF_UNIX) of the underlying socket of this client connection.
Instance Variable reactor The class pointed to by _commonConnection should set this attribute in its constructor.
Instance Variable socketType The socket type constant (socket.SOCK_STREAM or socket.SOCK_DGRAM) of the underlying socket.
Method _finishInit Called by subclasses to continue to the stage of initialization where the socket connect attempt is made.
Method _setRealAddress Set the resolved address of this _BaseBaseClient and initiate the connection attempt.
Class Variable _commonConnection Subclasses must provide this attribute, which indicates the Connection-alike class to invoke __init__ and connectionLost on.
Instance Variable _closeSocket Subclasses must implement in order to close the socket in response to a terminated connection attempt.

Inherited from ClientMixin (via Client, _BaseTCPClient, BaseClient, _BaseBaseClient):

Instance Variable _tlsClientDefault Always True, indicating that this is a client connection, and by default when TLS is negotiated this class will act as a TLS client.

Inherited from Connection (via Client, _BaseTCPClient, BaseClient, _BaseBaseClient, ClientMixin):

Method doRead Calls self.protocol.dataReceived with all available data.
Method getHandle Return the socket for this connection.
Method getTcpKeepAlive Return if SO_KEEPALIVE is enabled.
Method getTcpNoDelay Return if TCP_NODELAY is enabled.
Method logPrefix Return the prefix to log with when I own the logging thread.
Method readConnectionLost Indicates read connection was lost.
Method setTcpKeepAlive Enable/disable SO_KEEPALIVE.
Method setTcpNoDelay Enable/disable TCP_NODELAY.
Method writeSomeData Write as much as possible of the given data to this TCP connection.
Instance Variable socket Undocumented
Method _closeWriteConnection Undocumented
Method _dataReceived Undocumented

Inherited from ConnectionMixin (via Client, _BaseTCPClient, BaseClient, _BaseBaseClient, ClientMixin, Connection):

Method loseConnection Close this connection after writing all pending data.
Method registerProducer Register a producer.
Method startTLS No summary
Method unregisterProducer Unregister a producer.
Method write Write some bytes to this connection, passing them through a TLS layer if necessary, or discarding them if the connection has already been lost.
Method writeSequence Write some bytes to this connection, scatter/gather-style, passing them through a TLS layer if necessary, or discarding them if the connection has already been lost.
Constant TLS A flag indicating whether TLS is currently in use on this transport. This is not a good way for applications to check for TLS, instead use twisted.internet.interfaces.ISSLTransport.

Inherited from FileDescriptor (via Client, _BaseTCPClient, BaseClient, _BaseBaseClient, ClientMixin, Connection, ConnectionMixin):

Method doWrite Called when data can be written.
Method fileno File Descriptor number for select().
Method loseWriteConnection Undocumented
Method pauseProducing Pause producing data.
Method resumeProducing Resume producing data.
Method startReading Start waiting for read availability.
Method startWriting Start waiting for write availability.
Method stopConsuming Stop consuming data.
Method stopProducing Stop producing data.
Method stopReading Stop waiting for read availability.
Method stopWriting Stop waiting for write availability.
Method writeConnectionLost Indicates write connection was lost.
Constant SEND_LIMIT Undocumented
Class Variable bufferSize Undocumented
Class Variable disconnecting Undocumented
Instance Variable dataBuffer Undocumented
Instance Variable disconnected Undocumented
Instance Variable offset Undocumented
Instance Variable producer Undocumented
Instance Variable producerPaused Undocumented
Method _isSendBufferFull Determine whether the user-space send buffer for this transport is full or not.
Method _maybePauseProducer Possibly pause a producer, if there is one and the send buffer is full.

Inherited from _SocketCloser (via Client, _BaseTCPClient, BaseClient, _BaseBaseClient, ClientMixin, Connection, ConnectionMixin, FileDescriptor, _ConsumerMixin, _LogOwner):

Instance Variable _shouldShutdown Set to True if shutdown should be called before calling close on the underlying socket.

Inherited from _AbortingMixin (via Client, _BaseTCPClient, BaseClient, _BaseBaseClient, ClientMixin, Connection, ConnectionMixin, FileDescriptor, _ConsumerMixin, _LogOwner, _SocketCloser):

Method abortConnection Aborts the connection immediately, dropping any buffered data.

def _connectDone(self): (source)

This is a hook for when a connection attempt has succeeded.

Here, we build the protocol from the twisted.internet.protocol.ClientFactory that was passed in, compute a log string, begin reading so as to send traffic to the newly built protocol, and finally hook up the protocol itself.

This hook is overridden by ssl.Client to initiate the TLS protocol.
