void osg::DVRLookupTable::setTouched (  const bool &  value  )  [inline]

! This is very tricky: ! It prevents the common constructor from beeing called when ! loading the FC from an osg file ! Loading will initialize "size" before "touched" and will thus ! not go in this brach - otherwhise "touched" is eventually ! altered and at this point the constructor is called if the !
