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

org.apache.poi.hslf.record.SlideListWithText
These are tricky beasts. They contain the text of potentially many (normal) slides. They are made up of several sets of - SlidePersistAtom - TextHeaderAtom - TextBytesAtom / TextCharsAtom - StyleTextPropAtom (optional) - TextSpecInfoAtom (optional) - InteractiveInfo (optional) - TxInteractiveInfoAtom (optional) and then the next SlidePersistAtom. Eventually, Slides will find the blocks that interest them from all the SlideListWithText entries, and refere to them For now, we scan through looking for interesting bits, then creating the helpful Sheet from model for them @author Nick Burch
