State tracking record for TLS startup parameters. Used to remember how
TLS should be started when starting it is delayed to wait for the output
buffer to be flushed.
| Instance Variables | bufferedData | A list which contains all the data which was written to the
transport after an attempt to start TLS was made but before the buffers
outstanding at that time could be flushed and TLS could really be started.
This is appended to by the transport's write and writeSequence methods
until it is possible to actually start TLS, then it is written to the
TLS-enabled transport.
|
| context | An SSL context factory object to use to start TLS.
|
| extra | An extra argument to pass to the transport's startTLS
method.
