I suppose it will work fine. Using recursion there is not a very good idea.
Also there are two keys that need to be followed: "XRefStm" and
"Prev". @Francesco
Pretto <cez...@gmail.com> maybe you could fix that in the new podofo?
Something like this could work for example (pseudocode):
xrefs - vector of xrefs (or stack);
checked - set of already checked xrefs;
xrefs.push_back(first xref - startxref);
while(!xrefs.empty())
{
XRefType xref = xrefs.back();
xrefs.pop_back();
if(checked.contains(xref))continue; // to avoid cycles
checked.insert(xref);
...
just check whether this is non-stream xref with trailer -
xrefstream contains just single "previous xref"
xrefs.push_back(next "XRefStm" key from trailer);
xrefs.push_back(next "Prev" key from trailer);
}
