/*
|
||||
\class UiGuiIndentServer
|
||||
\ingroup grp_Server
|
||||
\brief UiGuiIndentServer is in such an early state, that even the communication
|
||||
protocol isn't completely planned. So this class lacks documentation until
|
||||
I really know where all this will lead to.
|
||||
|
||||
The plan however is to have a server that receives commands for selecting an
|
||||
indenter and perhaps load some by the user predefined indenter config file. Then
|
||||
the client can send a text to it and will receive it formatted.
|
||||
The idea behind that is to make UiGUIs use as plugin or whatever more flexible.
|
||||
So the plugin is developed for Eclipse for example and it takes the client role,
|
||||
making it possible to use UiGUI from within Eclipse. Choosing a network protocol
|
||||
makes everything platform and programming language independent, so it doesn't
|
||||
matter for which application the plugin/client is developed.
