[cdt-dev] Setting project description confusion

[Vladimir Prus <vladimir@xxxxxxxxxxxxxxxx>]

Hi,

I am looking at SetCProjectDescriptionOperation.executeOperation()
and failing to understand why it is written this way. It basically
knows ICProjectDescription to set, and a project. However, instead
of setting that project description directly, it creates new
CProjectDescription, applies 'data' to it, and only then does:

	fPrjDescStorage.setCurrentDescription(fNewDescriptionCache, true);

What is the reason for this additional CProjectDescription instance?

Thanks,
Volodya
