-----------------------------------------
Summary: is o.a.p.cos.COSArray supposed to contain nulls?
Key: PDFBOX-5862
URL: https://issues.apache.org/jira/browse/PDFBOX-5862
Project: PDFBox
Issue Type: Improvement
Components: Documentation
Affects Versions: 3.0.2 PDFBox
Reporter: Dieter von Holten
inspection by spotbugs shows a warning at line 573, which references a null
from the list and compares it with the given value. When the list contains a
null, and a null is passed by the caller, this is considered a match and the
index is returned to the caller.
However, other locations in COSArray cannot deal with null entries in the list.
i propose:
1.) update the document to state whether null is a valid list-entry
2.) consider the use of COSNull when the caller tries to insert null. in this
case, the users (those who get() values out) of COSArray need to be aware of
the change
