[jira] Created: (PDFBOX-734) how to access a PDoutlineNode object's
parent without using its protected menthod getParent() ?
how to access a PDoutlineNode object's parent without using its protected menthod getParent() ?
-----------------------------------------------------------------------------------------------
Key: PDFBOX-734
URL: https://issues.apache.org/jira/browse/PDFBOX-734
Project: PDFBox
Issue Type: Bug
Affects Versions: 1.1.0
Environment: Window's platform, java
Reporter: Harry Lee
Priority: Blocker
I have some java codes that depend on the getParent() method to traverse the PDOutlineNode structure. They works fine with old version of PDFBox since this method is declared as a public method. Now it is changed to protected in the new version 1.1.0. How should I make my code work without extending or subclassing PDOutlineNode?

----------------------------------
So basiclly, outline nodes only contain PDOutlineItem nodes except the top node which is a PDDocumentOutline object (since PDDocumentOutline does not have parent). Am I right?

PDOutlineNode is the super-class for PDDocumentOutline and PDOutlineItem. PDDocumentOutline does not have a parent, so a public getParent() method doesn't make sense. PDOutlineItem has a parent, and so has a public getParent() method.

Hi, Johannes. Thanks for your comments. I am OK with the change from public to protected for PDOutlineNode's getParent(). But, PDOutlineNode is not a abstract class. I may have a mixed tree structure of objects of both PDOutlineNode and PDOutlineItem. How do I access the parent node of a PDOutlineNode object in my data structure?

Well, PDOutlineNode should rather be abstract, because there is no such concrete thing in PDF. Your outline nodes should either be PDDocumentOutline or PDOutlineItem objects.

Yes. For more information see the PDF 1.7 spec, section 12.3.3 Document Outline.
