	removes all registered assets and does something similar to Asset::unlink() on each to break cyclic dependencies (we can't use the real unlink()-function, because this will propagate, including calls to the AssetManager.

Member Function Documentation

void asset::DB::clear

(

)

throw () [inline]

As the destructor of DB needs to call clear(), this could result in segfaults. This doesn't seem to be a problem, though, because we register and process all assets and the net effect is just breaking any cyclic dependencies)
