There is another question, how can I accurately collect the number of
COSStream, if I rewrite the method of PDFParser, as follows, is the number
obtained in this way accurate?
public class MonitorPDFParser extends PDFParser {
private final ConcurrentHashMap<COSStream, String> TASK_MAP =
new ConcurrentHashMap<>();
private final AtomicLong cout = new AtomicLong(0);
protected COSStream parseCOSStream(COSDictionary dic) throws
IOException
{
COSStream stream = super.parseCOSStream(dic);
cout.incrementAndGet();
TASK_MAP.put(stream, "");
return stream;
}
}
