Detailed Description

The Hierarchy Content Provider (HCP) implements a ContentProvider for the UniversalContentBroker (UCB).

It provides access to a persistent, customizable hierarchy of contents (folders and links).

Exported Interfaces

provides three types of contents: Link, Folder and Root Folder.

HCP Contents

A HCP Link (HierarchyLinkContent) is a content which points to another (UCB) content. It is always contained in HCP Folder. A HCP Link has no children.
A HCP Folder (HierarchyFolderContent) is a container for other HCP Folders and HCP Links.
There is at most one instance of a HCP Root Folder ( HierarchyRootFolderContent ) at a time. All other HCP contents are children of this folder. The HCP Root Folder can contain HCP Folders and HCP Links. It has the URL "vnd.sun.star.hier:/".

URL Scheme for HCP Contents

Each HCP content has an identifier corresponding to the following scheme:

vnd.sun.star.hier:/<path>, where <path> is a hierarchical path of the form <name>/.../<name> and where <name> is a string encoded according to the URL conventions.
