Examples of org.apache.poi.hslf.record.PersistPtrHolder

org.apache.poi.hslf.record.PersistPtrHolder
General holder for PersistPtrFullBlock and PersistPtrIncrementalBlock records. We need to handle them specially, since we have to go around updating UserEditAtoms if they shuffle about on disk These hold references to where slides "live". If the position of a slide moves, then we have update all of these. If we come up with a new version of a slide, then we have to add one of these to the end of the chain (via CurrentUserAtom and UserEditAtom) pointing to the new slide location @author Nick Burch
