          (View In Hierarchy)
        
      Known subclasses: twisted.internet.ssl.Client
A transport for a TCP protocol; either TCPv4 or TCPv6.
Do not create these directly; use IReactorTCP.connectTCP.
Inherited from _BaseTCPClient:
| Instance Variable | connector | The Connectorwhich
is driving this_BaseTCPClient's
connection attempt. | 
| Instance Variable | addr | The address that this socket will be connecting to. (type: If IPv4, a 2- tupleof(str host, int port).  If 
IPv6, a 4-tupleof (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 IPv4AddressorIPv6Address. | 
| Method | getPeer | Returns an IPv4AddressorIPv6Address. | 
| Method | __repr__ | Undocumented | 
| Instance Variable | _addressType | The Twisted _IPAddress implementation for this client (type: IPv4AddressorIPv6Address) | 
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_TLSServerMixinto call the right methods to directly manipulate the transport, as is 
necessary for writing TLS-encrypted bytes (whereas those methods onServerwill 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_STREAMorsocket.SOCK_DGRAM) of the underlying socket. (type:int) | 
| Instance Variable | reactor | The class pointed to by _commonConnectionshould 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 attempts 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. Trueif the hostname of said address indicates a 
name that must be resolved by hostname lookup,Falseif 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__andconnectionLoston. (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 _BaseBaseClientand 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 | Indicates read connection was lost. | 
| Method | connectionLost | See abstract.FileDescriptor.connectionLost(). | 
| Method | logPrefix | Return the prefix to log with when I own the logging thread. | 
| Method | getTcpNoDelay | Return if TCP_NODELAYis enabled. | 
| Method | setTcpNoDelay | Enable/disable TCP_NODELAY. | 
| Method | getTcpKeepAlive | Return if SO_KEEPALIVEis enabled. | 
| Method | setTcpKeepAlive | Enable/disable SO_KEEPALIVE. | 
| Method | _dataReceived | Undocumented | 
| Method | _closeWriteConnection | Undocumented | 
Inherited from FileDescriptor (via BaseClient, Connection):
| Method | doWrite | Called when data can be written. | 
| Method | writeConnectionLost | Indicates write connection was lost. | 
| 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 | Resume producing data. | 
| Method | pauseProducing | Pause producing data. | 
| Method | stopProducing | Stop producing data. | 
| 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 | Noneif 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 resumeProducingon it when buffer space is available. | 
| Instance Variable | streamingProducer | boolorint | 
| 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 aninterfaces.ILoggingContextprovider. | 
Inherited from _SocketCloser (via BaseClient, Connection):
| Instance Variable | _shouldShutdown | Set to Trueifshutdownshould be called before 
callingcloseon 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 TruewhenabortConnectionis called. (type:bool) |
