logmanoriginal 95b99d42a4 bridges: Fix default return values and function scopes 
getURI and getName should fall back to parent::getURI or
parent::getName respectively if it cannot build propper
return values.

Functions defined by bridges should be made private to
prevent confusion with inherited functions
