service HierarchyAccess in module com::sun::star::configuration:: |
service HierarchyAccess;
provides access to a (by name) hierarchy of descendant elements.
Values that are direct or indirect descendants of this tree node can be retrieved. Non-value subnodes can be navigated using container interfaces. Other interfaces provide access to information about this node. Changes to values in the subtree can be monitored by event listeners.
Elements of this (by name) container that are not simple values are similar containers themselves, thus (recursively) forming a hierarchical tree.
Implementations of this service usually also implement service HierarchyElement , which concerns the complementary role of being accessible as an element of the hierarchy.
Exported Interfaces |
allows access to immediate children of this node.
XNameAccess::getByName
returns an any
holding either a simple value or an interface
on another HierarchyAccess if the child is not a simple value.
allows access to all descendants of this node
XHierarchicalNameAccess::getByHierarchicalName
returns an any
holding either a simple value or an interface
on another HierarchyAccess if the descendant is not a simple value.
allows attaching listeners to this node to monitor changes to immediate child nodes.
provides support for inexact names.
Exact names can be obtained for simple or hierarchical names for use in XNameAccess , XHierarchicalNameAccess , XPropertySet , etc.
