Tilman Hausherr commented on PDFBOX-6166:
-----------------------------------------
Yes it's an improvement. I looked back into my old posting and I didn't any
good idea. It should be documented in the javadoc in case we hit this in the
future.
> Improve some implementation flaws in NonSeekableRandomAccessReadInputStream

> Key: PDFBOX-6166
> URL: https://issues.apache.org/jira/browse/PDFBOX-6166
> Project: PDFBox
> Issue Type: Improvement
> Components: IO, Parsing
> Affects Versions: 3.0.6 PDFBox, 4.0.0
> Reporter: Andreas Lehmkühler
> Assignee: Andreas Lehmkühler
> Priority: Major
>
> [~tilman] found some flaws in the implementation of
> NonSeekableRandomAccessReadInputStream based on a posting from Daniel Gredler
> on the users mailinglist
> As NonSeekableRandomAccessReadInputStream is backed by an InputStream we have
> to think about the implementation of some methods as the length of the given
> inputStream isn't available at the beginning
> * length: the current implementation relies on the internal member "size"
> * available: the current default implementation relies on length()
> * readFully: the current default implementation relies on length()
