Ondemand Parser

[Andrea Vacondio <an...@gmail.com>]

Hi,
Not sure if this is the right channel, apologies if it's not.
I came across the on demand parser
https://issues.apache.org/jira/browse/PDFBOX-4569 and saw the last comment
regarding memory mapped files and the scratch files. I just wanted to chip
in and point our lib https://github.com/torakiki/sejda-io
It's a small I/O layer that we use in our PDFBox fork, it supports memory
mapped files and it provides the concept of View that we used to drop the
Scratch files and have the COSStream to directly read from the underlying
PDF source. We have been using it for 3 years now and we processed a
gazillion of PDF files in PDFsam Basic, PDFsam Visual and Sejda so it's
definitely battle tested. Feel free to use it or take inspiration from it.

Thanks for the valuable pointer and the offer. I'll definitely have a look at 
your code.
