Maruan Sahyoun commented on PDFBOX-4569:
----------------------------------------
Looking at the current code this is a huge step forward for a lot of common
usage patterns.
Given the comments above we might be missing a typical use case though which is
limiting the memory consumption even when going through the complete PDF.
That could be implemented with the on demand parser in two ways I'd think
- either by a kind of drop call where parsed objects will be freed
- by freeing them after they have been referenced but leaving it to a gigher
level to cache these
Thoughts?
I'm also happy if the case outlined is not covered but I think it's important
that we communicate that clearly - i.e. where the benefits are and which cases
might not benefit from the on demand approach.
