Examples of POIFSReader

org.apache.poi.poifs.eventfilesystem.POIFSReader
An event-driven reader for POIFS file systems. Users of this class first create an instance of it, then use the registerListener methods to register POIFSReaderListener instances for specific documents. Once all the listeners have been registered, the read() method is called, which results in the listeners being notified as their documents are read. @author Marc Johnson (mjohnson at apache dot org)
