*
* @brief A class that provides Transport Layer Security on top of a TCP socket.
*
* This class is a class cluster and returns a suitable OFTLSSocket subclass,
* if available.
*
* Subclasses need to override @ref accept, @ref lowlevelReadIntoBuffer:length:,
* @ref lowlevelWriteBuffer:length:, @ref lowlevelIsAtEndOfStream and
* @ref startTLSForHost:port:. In order to get access to the lowlevel TCP
* methods (you cannot call `super`, as the class is abstract), the private
* methods @ref TCPAccept, @ref lowlevelTCPReadIntoBuffer:length:,
* @ref lowlevelTCPWriteBuffer:length: and @ref lowlevelTCPIsAtEndOfStream are
* @ref lowlevelWriteBuffer:length: and @ref startTLSForHost:port:. The method
* @ref hasDataInReadBuffer should be overridden to return `true` if the TLS
* socket has cached unprocessed data internally, while returning
* `[super hasDataInReadBuffer]` if it does not have any unprocessed data. In
* order to get access to the lowlevel TCP methods (you cannot call `super`, as
* the class is abstract), the private methods @ref TCPAccept,
* @ref lowlevelTCPReadIntoBuffer:length: and
* @ref lowlevelTCPWriteBuffer:length: are provided.
* provided.
