/**
* @short An interface to HTML sinks
* @author Marc Mutz <mutz@kde.org>
*
* @deprecated KMail should be ported to Interface::HtmlWriter. This
* interface exposes internal working models. The queuing
* vs. writing() issues exposed here should be hidden by using two
* different implementations of KHTMLPartHtmlWriter: one for
* queuing, and one for writing. This should be fixed before the
* release, so we an keep the plugin interface stable.
*
* Operate this interface in one and only one of the following two
* modes:
*
* @section Sync Mode
*
* In sync mode, use #begin() to initiate a session, then
* #write() some chunks of HTML code and finally #end() the session.
*
* @section Async Mode
*
* In async mode, use #begin() to initialize a session, then
* #queue() some chunks of HTML code and finally end the
* session by calling #flush().
*
* Queued HTML code is fed to the html sink using a timer. For this
* to work, control must return to the event loop so timer events
* are delivered.
*
* @section Combined mode
*
* You may combine the two modes in the following way only. Any
* number of #write() calls can precede #queue() calls,
* but once a chunk has been queued, you @em must @em not
* #write() more data, only #queue() it.
*
* Naturally, whenever you queued data in a given session, that
* session must be ended by calling #flush(), not #end().
