Part of twisted.internet.tcp View Source View In Hierarchy
Known subclasses: twisted.internet.tcp.Client, twisted.internet.unix.Client
| 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. (type: tuple) |
| Method | createInternetSocket | (internal) Create a non-blocking socket using self.addressFamily, self.socketType. |
| Method | doConnect | Initiate the outgoing connection attempt. |
| 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 Server will go
through another layer of TLS if it has been enabled). |
| Method | _stopReadingAndWriting | Implement the POSIX-ish (i.e. twisted.internet.interfaces.IReactorFDSet)
method of detaching this socket from the reactor for _BaseBaseClient. |
| Method | _collectSocketDetails | Clean up references to the socket and its file descriptor. |
| Method | _connectDone | This is a hook for when a connection attempt has succeeded. |
Inherited from _BaseBaseClient:
| Instance Variable | addressFamily | The address family constant (socket.AF_INET,
socket.AF_INET6, socket.AF_UNIX) of the
underlying socket of this client connection. (type: int) |
| Instance Variable | socketType | The socket type constant (socket.SOCK_STREAM or
socket.SOCK_DGRAM) of the underlying socket. (type: int) |
| Instance Variable | reactor | The class pointed to by _commonConnection should set this
attribute in its constructor. (type: twisted.internet.interfaces.IReactorTime,
twisted.internet.interfaces.IReactorCore,
twisted.internet.interfaces.IReactorFDSet) |
| Method | resolveAddress | No summary |
| Method | failIfNotConnected | Generic method called when the attemps to connect failed. It basically cleans everything it can: call connectionFailed, stop read and write, delete socket related members. |
| Method | stopConnecting | If a connection attempt is still outstanding (i.e. no connection is yet established), immediately stop attempting to connect. |
| Method | connectionLost | No summary |
| Instance Variable | _requiresResolution | A flag indicating whether the address of this client will require name
resolution. True if the hostname of said address indicates a
name that must be resolved by hostname lookup, False if it
indicates an IP address literal. (type: bool) |
| Class Variable | _commonConnection | Subclasses must provide this attribute, which indicates the Connection-alike
class to invoke __init__ and connectionLost on. (type: type) |
| Instance Variable | _closeSocket | Subclasses must implement in order to close the socket in response to a
terminated connection attempt. (type: 1-argument callable; see _SocketCloser._closeSocket) |
| 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. |
Inherited from Connection:
| Instance Variable | logstr | prefix used when logging events related to this connection. (type: str) |
| Method | __init__ | |
| Method | getHandle | Return the socket for this connection. |
| Method | doRead | Calls self.protocol.dataReceived with all available data. |
| Method | writeSomeData | Write as much as possible of the given data to this TCP connection. |
| Method | readConnectionLost | Undocumented |
| Method | connectionLost | See abstract.FileDescriptor.connectionLost(). |
| Method | logPrefix | Return the prefix to log with when I own the logging thread. |
| Method | getTcpNoDelay | Undocumented |
| Method | setTcpNoDelay | Undocumented |
| Method | getTcpKeepAlive | Undocumented |
| Method | setTcpKeepAlive | Undocumented |
| Method | _dataReceived | Undocumented |
| Method | _closeWriteConnection | Undocumented |
Inherited from FileDescriptor (via Connection):
| Method | doWrite | Called when data can be written. |
| Method | writeConnectionLost | Undocumented |
| Method | write | Reliably write some data. |
| Method | writeSequence | Reliably write a sequence of data. |
| Method | loseConnection | Close the connection at the next available opportunity. |
| Method | loseWriteConnection | Undocumented |
| Method | stopReading | Stop waiting for read availability. |
| Method | stopWriting | Stop waiting for write availability. |
| Method | startReading | Start waiting for read availability. |
| Method | startWriting | Start waiting for write availability. |
| Method | stopConsuming | Stop consuming data. |
| Method | resumeProducing | Undocumented |
| Method | pauseProducing | Undocumented |
| Method | stopProducing | Undocumented |
| Method | fileno | File Descriptor number for select(). |
| Method | _postLoseConnection | Called after a loseConnection(), when all data has been written. |
| 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 _ConsumerMixin (via Connection, FileDescriptor):
| Instance Variable | producer | None if no producer is registered, otherwise the registered
producer. |
| Instance Variable | producerPaused | A flag indicating whether the producer is currently paused. (type: bool) |
| Instance Variable | streamingProducer 0 | A flag indicating whether the producer was registered as a streaming (ie
push) producer or not (ie a pull producer). This will determine whether
the consumer may ever need to pause and resume it, or if it can merely call
resumeProducing on it when buffer space is available. |
| Instance Variable | streamingProducer | bool or int |
| Method | registerProducer | Register to receive data from a producer. |
| Method | unregisterProducer | Stop consuming data from a producer, without disconnecting. |
Inherited from _LogOwner (via Connection, FileDescriptor):
| Method | _getLogPrefix | Determine the log prefix to use for messages related to
applicationObject, which may or may not be an interfaces.ILoggingContext
provider. |
Inherited from _SocketCloser (via Connection):
| Instance Variable | _shouldShutdown | Set to True if shutdown should be called before
callling close on the underlying socket. (type: bool) |
| Method | _closeSocket | Undocumented |
Inherited from _AbortingMixin (via Connection):
| Method | abortConnection | Aborts the connection immediately, dropping any buffered data. |
| Instance Variable | _aborting | Set to True when abortConnection is called. (type: bool) |

| Note | Applications do not need to call this method; it will be invoked internally
as part of IReactorTCP.connectTCP. | |
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.
