[cdt-dev] How to restart the language provider scanner?

[Jan Baeyens <jan@xxxxxxxxxx>]

Hi
In my eclipse plugin I have project settings that when I change them The 
language provider needs to be rerun because I'm using another compiler.
I found a way in the gui to rerun the language provider (project 
properties->C/C++ General->Code Analysis->Preprocessor Include Paths, 
Maros etc Select providers tab; select the provider;Select reset; select OK
Sometimes the reset is not enabled in which case you can change the 
command as work around.
Eclipse spy tells me the button is on LanguageSettingProviderPage but I 
failed to find the code.
My question is: What is the API code to force the language provider to 
rerun?
Best regards
Jantje
