             Summary: Preflight cookbook example is inefficient
                 Key: PDFBOX-3007
                 URL: https://issues.apache.org/jira/browse/PDFBOX-3007
             Project: PDFBox
          Issue Type: Bug
          Components: Documentation
    Affects Versions: 1.8.10, 1.8.11, 2.0.0
            Reporter: Tilman Hausherr
             Fix For: 1.8.11, 2.0.0


The example shown in
http://pdfbox.apache.org/1.8/cookbook/pdfavalidation.html
passes a DataSource object. This results in the creation of a temporary file. The constructor with the DataSource makes only sense when working with URLs. (And that only if http is cached, because preflight does an openStream() for each PDF stream!)

It would be better to replace
{code}
FileDataSource fd = new FileDataSource(args[0]);
PreflightParser parser = new PreflightParser(fd);
{code}
with
{code}
PreflightParser parser = new PreflightParser(args[0]);
{code}

When working on that one, the example could also be copied to the 2.0 cookbook directory.
