      • unloadReplacedObjects

        public void unloadReplacedObjects()
        provides an external hook to unload all files which have already been merged.

        Merging produces a copy of an entity, so that all old entities should be considered stale. By unloading them, one is forcing the API user to use the replacement instead.

        The replacement is set by MergeEventListener and this is the signal that that entity can be unloaded. Usually, this method is invoked by UpdateImpl
