[jira] Commented: (PDFBOX-734) how to access a PDoutlineNode object's parent without using its protected menthod getParent() ?

["Johannes Koch (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/PDFBOX-734?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12873297#action_12873297 ] 

Johannes Koch commented on PDFBOX-734:
--------------------------------------

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.

> 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?
