| |
| <p>An implementation represents the root of a partial hierarchy. [See the |
| documentation for <type>AccessRootElement</type>]. The hierarchy in turn is |
| a <em>view</em> onto a fragment of persistent data tree that can be accessed |
| through several such views, or even several processes, simultaneously. |
| </p> |
| |
| <p>Elements of the hierarchy, such as descendants of this root element, |
| may support modification by providing appropriate |
| interfaces. Changes done this way initially only affect these objects |
| themselves and other objects within the same hierarchy, such as other |
| descendants of this root element. |
| </p> |
| |
| <p>The accumulated changes within this hierarchy can be managed using |
| <type scope="com::sun::star::util">XChangesBatch</type>. Pending changes |
| will become persistent and visible from other overlapping hierarchies |
| only when <member scope="com::sun::star::util">XChangesBatch::commitChanges()</member> |
| is called. If the hierarchy is disposed or discarded without committing |
| changes, the changes will be lost. |
