Part of twisted.internet.tcp View Source View In Hierarchy
Known subclasses: twisted.internet.ssl.Client
Do not create these directly; use IReactorTCP.connectTCP.
Inherited from _BaseTCPClient:
| Instance Variable | connector | The Connector which
is driving this _BaseTCPClient's
connection attempt. |
| Instance Variable | addr | The address that this socket will be connecting to. (type: If IPv4, a 2-tuple of (str host, int port). If
IPv6, a 4-tuple of (str host, int port, int ignored, int
scope).) |
| Instance Variable | createInternetSocket | Subclasses must implement this as a method to create a python socket object
of the appropriate address family and socket type. (type: 0-argument callable returning socket._socketobject.) |
| Method | __init__ | Undocumented |
| Method | getHost | Returns an IPv4Address
or IPv6Address. |
| Method | getPeer | Returns an IPv4Address
or IPv6Address. |
| Method | __repr__ | Undocumented |
| Instance Variable | _addressType | The Twisted _IPAddress implementation for this client (type: IPv4Address
or IPv6Address) |
Inherited from BaseClient:
| 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 (via BaseClient):
| 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 (via BaseClient):
| 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 BaseClient, 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 BaseClient, 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 BaseClient, 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 BaseClient, 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 BaseClient, Connection):
| Method | abortConnection | Aborts the connection immediately, dropping any buffered data. |
| Instance Variable | _aborting | Set to True when abortConnection is called. (type: bool) |
