Tilman Hausherr commented on PDFBOX-5489:
-----------------------------------------
I tried this with the file of PDFBOX-4149 (and noticed I can't pass a document):
{code}
PDDocument doc = Loader.loadPDF(new File("PDFBOX-4149-veryslow.pdf"));
List<COSObjectKey> indirectObjectKeys = new ArrayList<>();
long t0 = System.currentTimeMillis();
doc.getDocumentCatalog().getCOSObject().getIndirectObjectKeys(indirectObjectKeys);
long highestImportedNumber =
indirectObjectKeys.stream().map(COSObjectKey::getNumber).max(Long::compare).get();
System.out.println(indirectObjectKeys.size());
long t1 = System.currentTimeMillis();
System.out.println("highestImportedNumber: " + highestImportedNumber);
System.out.println((t1-t0)/1000f);
{code}
The output is:
2
highestImportedNumber: 3
0.038
This is suspiciously low... looking at the code of {{getIndirectObjectKeys}},
now I see you don't go through arrays.
