public class Outlines
extends Dictionary

This class represents a PDF document outline. A document outline is an optional component of a PDF document and is accessible from the document's Catalog. The outline consists of a tree-structured hierarchy of outline items (sometimes called bookmarks) which can be used to display a documents structure to the user.

The outlines class does not build a visible structure; it only represents the non-visual structure of the outline. The OutlineItemTreeNode available in the packageorg.icepdf.core.ri.common provides an example on converting this hierarchy to a Swing JTree.
