provides modifying access to a fragment of the configuration hierarchy.
Extends ConfigurationAccess to support modifying values
or inserting and removing elements.
Descendants of this service also implement this service
unless they are marked read-only (which is indicated by attribute
PropertyAttribute::READONLY),
in which case they only need implement ConfigurationAccess.
The classification of implementations that is described for
ConfigurationAccess applies to implementations of this service
as well. Therefore an implementation will support one of several alternate
services describing its Container role and one of several alternate
services describing its Element role. These services are
extensions of the respective services documented for ConfigurationAccess.
Container role:
A group permits changing child values.
A set permits inserting and removing contained elements.
Element role:
The root element of a modifiable tree provides extended functionality
to control processing of changes for the entire tree (fragment) by
supporting ::com::sun::star::util::XChangesBatch.
For elements of a set or a group no additinal
interfaces are supported.
is the basic service providing read access to an element of the
configuration hierarchy and its child and descendent elements.
The HierarchyAccess specialization implemented will be
further specialized to support modifying access.
Implementations shall therefore implement one of SetUpdate or
GroupUpdate depending on the Container role.
If the HierarchyElement specialization that is implemented
is AccessRootElement, the implementation must support the
extended functionality of UpdateRootElement. Otherwise, there
are no new requirements mandated by the Element role.
