|
|
*
|
|
* @deprecated KMail should be ported to Interface::HtmlWriter. This
|
|
* interface exposes internal working models. The queueing
|
|
* vs. writing() issues exposed here should be hidden by using two
|
|
* different implementations of KHTMLPartHtmlWriter: one for
|
|
* queueing, 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().
