## org.apache.poi.hslf.dev
Class SlideShowDumper

    java.lang.Object
      org.apache.poi.hslf.dev.SlideShowDumper

    public final class SlideShowDumper

extends java.lang.Object

This class provides a way to "peek" inside a powerpoint file. It will print out all the types it find, and for those it know aren't atoms, what they contain To figure out what things are, and if they are atoms or not, used the list in hslf.record.RecordTypes To peek inside PPDrawings, which hold Escher drawings, we use the DDF package from POI (but we can fake it by using the Escher listings from hslf.record.RecordTypes also)

Constructor Summary
`SlideShowDumper(NPOIFSFileSystem filesystem, java.io.PrintStream out)` Constructs a Powerpoint dump from a POIFS Filesystem.

Method Summary
`static void` | `main(java.lang.String[] args)` right now this function takes one parameter: a ppt file, and outputs a dump of what it contains
`void` | `printDump()`
`void` | `setBasicEscher(boolean grok)` Control dumping of any Escher records found - should our built in basic groker be used?
`void` | `setDDFEscher(boolean grok)` Control dumping of any Escher records found - should DDF be used?
`void` | `walkEscherBasic(int indent, int pos, int len)` Use the basic record format groking code to walk the Escher records
`void` | `walkEscherDDF(int indent, int pos, int len)` Use the DDF code to walk the Escher records
`void` | `walkTree(int depth, int startPos, int maxLen)`

### SlideShowDumper

    public SlideShowDumper(NPOIFSFileSystem filesystem,
                           java.io.PrintStream out)
                    throws java.io.IOException

  Constructs a Powerpoint dump from a POIFS Filesystem. Parses the document and dumps out the contents

  Parameters:
    `filesystem` - the POIFS FileSystem to read from
  Throws:
    `java.io.IOException` - if there is a problem while parsing the document.
