Re: dump COSDictionary recursively

Hello all,

has anybody a working solution or a guide for me how to achieve this:

Given a COSDictionary object how would I get a recursive text dump of
all its subobject?

I tried something like:

   PDDocument doc = PDDocument.load(file);
   PDDocumentCatalog catalog = doc.getDocumentCatalog();
   List<PDPage> allPages = catalog.getAllPages();
   for (PDPage page : allPages) {
     COSDictionary pageDict = page.getCOSDictionary();
     for (Entry<COSName, COSBase> entry : pageDict.entrySet()) {
       if (value instanceof COSArray)
         // process array
       else if (value instanceof COSString)
         // process String
       else if (value instanceof COSObject)
         // stuck
     }
   }

I'm stuck how to recurse into the COSObject.

Try something like this to get the encapsulated object:

COSBase baseObject = ((COSObject)value).getObject();

pageDict.toString() gives me some overview:

COSDictionary{
   (COSName{Annots}:COSArray{[COSObject{19, 0}, COSObject{20, 0}]})

but also doesn't go deeper into the "Annots" object.


Thanks for your help

Do you need the information for a further process or are you just interested to
see those information for debugging purposes or something similar? Maybe you
should try the PDFDebugger.
