PDFBOX-4288: don't add objects that are already fully parsed and are ignored
later, as suggested by Hee Jeong Kim
> needless adding while parsing dictionary objects
> ------------------------------------------------
>
> Key: PDFBOX-4288
> URL: https://issues.apache.org/jira/browse/PDFBOX-4288
> Project: PDFBox
> Issue Type: Bug
> Components: Parsing
> Affects Versions: 2.0.11
> Reporter: Hee Jeong Kim
> Priority: Minor
> Labels: optimization
> Attachments: needless_adding_while_parsing_dictionary_objects.patch
>
>
> Hi, It seems like unnecessary objects(COSNull, COSFloat..) are also added to
> 'toBeParsedList' while parsing dictionary objects and this can impact on
> performance.
> You can download a file causing out of memory exception while parsing
> dictionary objects below,
> https://turnernbahangtime.files.wordpress.com/2017/10/2017-18-official-nba-guide_v2.pdf
> and please check the attached patch that avoids unnecessary adding operations.
