public class NameResourcesDuplicator
extends Object
implements Consumer<org.sejda.sambox.pdmodel.PDPage>

Component that duplicates parts of the page resource dictionary that are relevant for the hit and clean process. The idea is that we want to hit and clean a resource dictionary that is relevant only for the given page, and not potentially shared with other pages (e.g. if page is a copy we don't want to clean the resource dictionary of the original page). I'm not sure this is needed. Resource dictionaries may come from other places (XForm, ExtGState softmasks..) so we are already hitting/cleaning shared resource dictionaries. The reason why the whole hit/clean process works is because the ExistingIndirectCOSObject holding the resources is unloaded from the LazyIndirectObjectsProvider once the file is written, this way the next cycle reloads the resources getting a brand new resource dictionary, untouched by the previous hit/clean process.
