provides access to a hierarchy of descendant elements.
Subnodes are accessed by their name. 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 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.
interface com::sun::star::beans::XExactName |
provides support for inexact names.
Exact names can be obtained for simple or hierarchical names for use in com::sun::star::container::XNameAccess, com::sun::star::container::XHierarchicalNameAccess, com::sun::star::beans::XPropertySet or any other interfaces that allow access to or manipulation of subnodes selected by name or hierarchical name.
If an inexact name could be matched to either a simple or a hierarchical name, the simple (immediate child) name is preferred.
|
optional |
provides access to the states of multiple child elements of an implementation.
[optional]
This interface may be missing if the hierarchy (or a hierarchy fragment that contains this implementation as element) does not support default values if the node does not support accessing the default state of individual children.
If elements that are not simple values, but objects themselves, support a default state (as indicated by com::sun::star::beans::PropertyAttribute::MAYBEDEFAULT), they should implement com::sun::star::beans::XPropertyWithState, in which case the com::sun::star::beans::PropertyState applies to all their children and recursively to all descendants.
If an implementation is part of a read-only view of the hierarchy, attempts to change property states will fail.
|
optional |
provides information about immediate children of this node.
[optional]
This interface may be missing, if the hierarchy supports no traits that are described by com::sun::star::beans::PropertyAttribute values or if the same information is available by other means, e.g. if the implementation supports com::sun::star::beans::XPropertySet::getPropertySetInfo().
If a child of this node is an object that implements com::sun::star::beans::XProperty, then this implementation returns the same com::sun::star::beans::Property for that child as the child itself.

optional |
provides access to the state of child elements of an implementation.
[optional]
This interface may be missing if the hierarchy (or a hierarchy fragment that contains this implementation as element) does not support default values or if the node does not support accessing the default state of individual children.
If elements that are not simple values, but objects themselves, support a default state (as indicated by com::sun::star::beans::PropertyAttribute::MAYBEDEFAULT), they should implement com::sun::star::beans::XPropertyWithState, in which case the com::sun::star::beans::PropertyState applies to all their children and recursively to all descendants.
If an implementation is part of a read-only view of the hierarchy, attempts to change property states will fail.
interface com::sun::star::container::XContainer |
allows attaching listeners to this node to monitor changes to immediate child nodes.
allows access to all descendants of this node
com::sun::star::container::XHierarchicalNameAccess::getByHierarchicalName() returns an any
holding either a simple value or an interface on another HierarchyAccess if the descendant is not a simple value.
interface com::sun::star::container::XNameAccess |
allows access to immediate children of this node.
com::sun::star::container::XNameAccess::getByName() returns an any
holding either a simple value or an interface on another HierarchyAccess if the child is not a simple value.
