PDFBOX-5483: replace InputStream with RandomAccessRead
> Replace methods using an InputStream from Loader.loadPDF
> --------------------------------------------------------
>
> Key: PDFBOX-5483
> URL: https://issues.apache.org/jira/browse/PDFBOX-5483
> Project: PDFBox
> Issue Type: Improvement
> Components: Parsing
> Affects Versions: 3.0.0 PDFBox
> Reporter: Andreas Lehmkühler
> Assignee: Andreas Lehmkühler
> Priority: Major
> Fix For: 3.0.0 PDFBox
>

> As discussed on dev@pdfbox
> {quote}
> We have to remove the loadPDF variants using InputStream and replace them
> with RandomAccessRead.
> If it comes to InputStreams users have to decide how to procide:
> * copy the InputStream to memory by using RandomAccessReadBuffer
> * copy the InputStream to a file and use RandomAccessReadBufferedFile or
> RandomAccessReadMemoryMappedFile
> This would make it more transparent what happens under the hood when using
> the different kinds of loadPDF methods:
> * a byte array as source is already in memory and the obvious choice is to
> use RandomAccessReadBuffer as a wrapper
> * a file as source targets a local file and the most obvious choice is to use
> RandomAccessReadBufferedFile as a wrapper. We should document that as the
> other alternative RandomAccessReadMemoryMappedFile is offered in this case
> * RandomAccessRead as source is the most obvious one and the user decides how
> to create it. Additionally is ist possible to implement some own caching
> loading and/or mechanism
