twisted.internet.iocpreactor.tcp.Connection : API documentation

Known subclasses: twisted.internet.iocpreactor.tcp.Client, twisted.internet.iocpreactor.tcp.Server

Implements interfaces: twisted.internet.interfaces.ISystemHandle, twisted.internet.interfaces.ITCPTransport, twisted.internet.interfaces.ITLSTransport, twisted.internet.iocpreactor.interfaces.IReadWriteHandle

Instance Variable	TLS	`False` to indicate the connection is in normal TCP mode, `True` to indicate that TLS has been started and that operations must be routed through the `TLSMemoryBIOProtocol` instance.
Method	__init__	Undocumented
Method	getHandle	Return a system- and reactor-specific handle.
Method	dataReceived	Undocumented
Method	readFromHandle	Read into the given buffers from this handle.
Method	writeToHandle	Send `buff` to current file handle using `_iocp.send`. The buffer sent is limited to a size of `self.SEND_LIMIT`.
Method	readConnectionLost	Indicates read connection was lost.
Method	connectionLost	The connection was lost.
Method	logPrefix	Return the prefix to log with when I own the logging thread.
Method	getTcpNoDelay	Return if `TCP_NODELAY` is enabled.
Method	setTcpNoDelay	Enable/disable `TCP_NODELAY`.
Method	getTcpKeepAlive	Return if `SO_KEEPALIVE` is enabled.
Method	setTcpKeepAlive	Enable/disable `SO_KEEPALIVE`.
Method	startTLS
Method	write	Write some data, either directly to the underlying handle or, if TLS has been started, to the `TLSMemoryBIOProtocol` for it to encrypt and send.
Method	writeSequence	Write some data, either directly to the underlying handle or, if TLS has been started, to the `TLSMemoryBIOProtocol` for it to encrypt and send.
Method	loseConnection	Close the underlying handle or, if TLS has been started, first shut it down.
Method	registerProducer	Register a producer.
Method	unregisterProducer	Unregister a producer.
Method	_closeWriteConnection	Undocumented

Inherited from _AbortingMixin:

Method	abortConnection	Aborts the connection immediately, dropping any buffered data.
Instance Variable	_aborting	Set to `True` when `abortConnection` is called. (type: `bool`)

TLS =

False to indicate the connection is in normal TCP mode, True to indicate that TLS has been started and that operations must be routed through the TLSMemoryBIOProtocol instance.

def __init__(self, sock, proto, reactor=None): (source)

overrides twisted.internet.iocpreactor.abstract.FileHandle.__init__

overridden in twisted.internet.iocpreactor.tcp.Client, twisted.internet.iocpreactor.tcp.Server

Undocumented

def getHandle(self): (source)

from twisted.internet.interfaces.ISystemHandle

Return a system- and reactor-specific handle.

This might be a socket.socket() object, or some other type of object, depending on which reactor is being used. Use and manipulate at your own risk.

This might be used in cases where you want to set specific options not exposed by the Twisted APIs.

def dataReceived(self, rbuffer): (source)

overrides twisted.internet.iocpreactor.abstract.FileHandle.dataReceived

Undocumented

def readFromHandle(self, bufflist, evt): (source)

from twisted.internet.iocpreactor.interfaces.IReadHandle

overrides twisted.internet.iocpreactor.abstract.FileHandle.readFromHandle

Read into the given buffers from this handle.

Parameters	buff	the buffers to read into (type: list of objects implementing the read/write buffer protocol)
	evt	an IOCP Event object
Returns	tuple (return code, number of bytes read)

def writeToHandle(self, buff, evt): (source)

from twisted.internet.iocpreactor.interfaces.IWriteHandle

overrides twisted.internet.iocpreactor.abstract.FileHandle.writeToHandle

Send buff to current file handle using _iocp.send. The buffer sent is limited to a size of self.SEND_LIMIT.

def _closeWriteConnection(self): (source)

overrides twisted.internet.iocpreactor.abstract.FileHandle._closeWriteConnection

Undocumented

def readConnectionLost(self, reason): (source)

from twisted.internet.interfaces.IHalfCloseableDescriptor

overrides twisted.internet.iocpreactor.abstract.FileHandle.readConnectionLost

Indicates read connection was lost.

def connectionLost(self, reason): (source)

overrides twisted.internet.iocpreactor.abstract.FileHandle.connectionLost

The connection was lost.

This is called when the connection on a selectable object has been lost. It will be called whether the connection was closed explicitly, an exception occurred in an event handler, or the other end of the connection closed it first.

Clean up state here, but make sure to call back up to FileDescriptor.

def logPrefix(self): (source)

from twisted.internet.interfaces.ILoggingContext

overrides twisted.internet.abstract._LogOwner.logPrefix

Return the prefix to log with when I own the logging thread.

def getTcpNoDelay(self): (source)

from twisted.internet.interfaces.ITCPTransport

Return if TCP_NODELAY is enabled.

def setTcpNoDelay(self, enabled): (source)

from twisted.internet.interfaces.ITCPTransport

Enable/disable TCP_NODELAY.

Enabling TCP_NODELAY turns off Nagle's algorithm. Small packets are sent sooner, possibly at the expense of overall throughput.

def getTcpKeepAlive(self): (source)

from twisted.internet.interfaces.ITCPTransport

Return if SO_KEEPALIVE is enabled.

def setTcpKeepAlive(self, enabled): (source)

from twisted.internet.interfaces.ITCPTransport

Enable/disable SO_KEEPALIVE.

Enabling SO_KEEPALIVE sends packets periodically when the connection is otherwise idle, usually once every two hours. They are intended to allow detection of lost peers in a non-infinite amount of time.

def startTLS(self, contextFactory, normal=True): (source)

from twisted.internet.interfaces.ITLSTransport
