Method Details

doRead(self)

See tcp.Connection.doRead for details.
Overrides:
twisted.internet.tcp.Connection.doRead

doWrite(self)

Called when data is available for writing.

A result that is true (which will be a negative number) implies the connection was lost. A false result implies the connection is still there; a result of 0 implies no write was done, and a result of None indicates that a write was done.
Overrides:
twisted.internet.abstract.FileDescriptor.doWrite (inherited documentation)

getPeerCertificate(self)

Return the certificate for the peer.

writeSomeData(self, data)

See tcp.Connection.writeSomeData for details.
Overrides:
twisted.internet.tcp.Connection.writeSomeData

_closeSocket(self)

Called to close our socket.
Overrides:
twisted.internet.tcp.Connection._closeSocket

_postLoseConnection(self)

Gets called after loseConnection(), after buffered data is sent.

We close the SSL transport layer, and if the other side hasn't closed it yet we start reading, waiting for a ZeroReturnError which will indicate the SSL shutdown has completed.
Overrides:
twisted.internet.abstract.FileDescriptor._postLoseConnection
