Gilad Denneboom updated PDFBOX-1209:
------------------------------------
Description:
At the moment it's not possible to insert a first child to a pre-existing
PDDocumentOutline because all the available methods only allow you to add a
PDOutlineItem at the end of the list (PDDocumentOutline.appendChild()) or after
an existing child (PDOutlineItem.insertSiblingAfter()). As a result, if you
wish to insert a new first child, you have to manually traverse and re-create
the entire tree, which is ridiculous.
As a solution, I offer to add a new method to the PDOutlineItem class,
insertSiblingBefore(). I've written the code necessary based on
insertSiblingAfter(). It's very straight-forward...
/**
* Insert a sibling before this node.
*
* @param item The item to insert.
*/
public void insertSiblingBefore( PDOutlineItem item )
{
item.setParent( getParent() );
PDOutlineItem previous = getPreviousSibling();
setPreviousSibling( item );
item.setNextSibling( this );
if( previous != null )
{
item.setPreviousSibling( previous );
previous.setNextSibling( item );
}
updateParentOpenCount( 1 );
}
I hope this can be integrated in the next release...
