+
+ <p>Shared sets of configuration data usually serve to provide defaults,
+ which are used if no individual settings are present. Depending on the data
+ store multiple layers of defaults may be combined with a user-specific layer
+ to make up the final configuration.
+ </p>
+ <p>Many aspects of the supported behavior depend strongly on the underlying
+ data store and on the administrative structures it defines. With some data
+ stores this service also enables access to individual user's configuration
+ data by an administrator.
+ </p>
+ <p>On the other hand, in the simplest model there is only a single layer of
+ default data which is accessible through this service.
+ </p>
+ <p>An implementation is usually obtained from a
+ com::sun::star::lang::ServiceManager. The arguments passed to
+ com::sun::star::lang::XMultiComponentFactory::createInstanceWithArgumentsAndContext()

+/** allows creating access objects for specific views such as subsets and fragments

+
+ <p>The parameter <var>aServiceSpecifier</var> passed to
+ com::sun::star::lang::XMultiServiceFactory::createInstanceWithArguments()
+ supports at least the service specifiers
+ <code>"com.sun.star.configuration.ConfigurationAccess"</code> and
+ <code>"com.sun.star.configuration.ConfigurationUpdateAccess"</code>.
+ </p>
+
+ <p>Using the first of these service specifiers requests a read-only view of
+ the configuration.
+ The object that is created implements service ConfigurationAccess.
+ To reflect its <em>element role</em> as root of the view, it implements
+ service AccessRootElement.
+ </p>
+
+ <p>Using the second form requests an updatable view of the configuration.
+ The object that is created should implement service
+ ConfigurationUpdateAccess. To reflect its <em>element role</em>
+ which includes controlling updates for the whole view, it implements
+ service UpdateRootElement.
+ <BR />If the root element of the view is marked read-only (as indicated
+ by com::sun::star::beans::PropertyAttributes::READONLY),
+ the implementation may either raise an exception or return a (read-only)
+ ConfigurationAccess/AccessRootElement instead.
+ </p>
+
+ <p>The arguments passed to
+ com::sun::star::lang::XMultiServiceFactory::createInstanceWithArguments()
+ in parameter <var>aArguments</var> specify the administrative entity for which
+ data should be administered. In other words they determine the layer to which
+ changes will apply. They also specify the view of that configuration that
+ should be created. That is, they determine the subset of elements that can be
+ accessed starting from the returned object. Each element of the argument
+ sequence should be a com::sun::star::beans::PropertyValue
+ or a com::sun::star::beans::NamedValue,
+ so that the parameters can be identified by name rather than by position.
+ </p>
+
+ <p>What combinations of arguments are supported depends on the service name
+ and on the data store being administered.
+ </p>
+
+ <p>With both of the standard service-specifiers above, an implementation must
+ accept a single argument named <code>nodepath</code> of type `string`.
+ This argument must contain the absolute path to an element of the
+ configuration. The view that is selected consists of the named element and
+ all its descendants. The administrative entity is the default for the
+ AdministrationProvider. Usually this is the largest entity
+ encompassing all entities accessible from this instance. In other words this
+ can be used to influence as global a scope as possible.
+ </p>
+
+ <p>Other arguments can be used to select a more specific entity and to control
+ the behavior of the view. These are different for different implementations
+ and data stores. Whether and how they are used may also depend on properties
+ that were selected when the provider was created.
+ </p>
+
+ <p>An implementation may ignore unknown arguments.</p>
+
+ <p>Some parameters that are commonly supported are described for service
+ ConfigurationProvider.
+ </p>
+ <p>One notable difference exists for parameter <code>"Locale"</code>. For a
+ ConfigurationProvider the default behavior usually is to select
+ the locale set up for the user. But this service by default gets data for all
+ locales for which data is present. Locale-dependent values in this case are
+ replaced by a SetAccess using the language names as accessors.
+ This also allows targeted setting of values for selected locales.
+ This behavior can be requested explicitly by specifying a special argument
+ value <code>locale = "*"</code>.
+ </p>
+
+ <p>com::sun::star::lang::XMultiServiceFactory::createInstance()
+ may be unusable. Only an implementation that supports service names that can be
+ used with no further arguments support this method. It should return the
+ same result as if
+ com::sun::star::lang::XMultiServiceFactory::createInstanceWithArguments()
+ had been called using an empty sequence of arguments.

+ access to information about this element and its context.
+ Changes to values in the hierarchy can be monitored by event listeners.
+ </p>
+
+ <p>Descendants of this service also implement this service.
+ </p>
+
+ <p>Ultimately the configuration holds values. These values are organized into
+ a hierarchy using structural elements. The structure is defined in advance in
+ a schema. Necessary information from the schema is stored in the configuration
+ repository itself and is accessible through an implementation of this service.
+ </p>
+
+ <p>Two different kinds of structural elements are used in the configuration
+ hierarchy:
+ </p>
+ <dl>
+    <dt>Sets</dt>
+        <dd>are dynamic containers of homogeneous elements. Which elements
+        a <em>set</em> contains can vary. Their names are defined by the
+        clients that insert them. On the other hand, the <em>type</em> of
+        the elements is the same for all elements. In the case of elements
+        that are themselves hierarchy objects, the <em>type</em> includes
+        the structure of the hierarchy fragment they contain. Such types
+        are defined in the configuration schema as <em>templates</em>.
+        </dd>
+
+    <dt>Groups</dt>
+        <dd>are static collections of heterogeneous elements. The names and
+        types of the elements of a <em>group</em> are completely defined in the
+        configuration schema. Here each element may be of a different
+        <em>type</em>, allowing <em>groups</em> that contain a mix of
+        subobjects and simple values.
+        </dd>
+ </dl>
+
+ <p>Objects in the configuration hierarchy, for example, implementations of this service,
+ can thus be classified in the following ways:
+ </p>
+ <ul>
+    <li><em>Container</em> role:
+        An object that can hold child elements as a <em>set</em> or a <em>group</em>.
+    </li>
+    <li><em>Element</em> role:
+        An object may be an element of a <em>set</em> or a <em>group</em>
+        or else it may be the root element.
+    </li>
+ </ul>
+
+ <p>Several types of simple <em>values</em> can be used in the configuration.
+ In addition to the basic (scalar) types, sequences of the basic types are
+ supported. The basic types are:
+ </p>
+
+ <ul>
+    <li><strong>string</strong> can hold a human-readable text.
+        <p>Values are represented as `string`.</p>
+        <p>Sequences are represented as `string[]`.</p>
+        <p>"<em>human-readable</em>" here excludes non-printing characters
+        except for CR, LF and TAB [Unicode code points 9,10,13].
+        For binary data, use type <strong>binary</strong> instead.</p>
+    </li>
+    <li><strong>boolean</strong> can hold the values `TRUE` or `FALSE`.
+        <p>Values are represented as `boolean`.
+        <p>Sequences are represented as `boolean[]`.</p>
+    </li>
+    <li><strong>short</strong> can hold a 16-bit signed integer.
+        <p>Values are represented as `short`.</p>
+        <p>Sequences are represented as `short[]`.</p>
+    </li>
+    <li><strong>int</strong> can hold a 32-bit signed integer.
+        <p>Values are represented as `long`.</p>
+        <p>Sequences are represented as `long[]`.</p>
+    </li>
+    <li><strong>long</strong> can hold a 64-bit signed integer.
+        <p>Values are represented as `hyper`.</p>
+        <p>Sequences are represented as `hyper[]`.</p>
+    </li>
+    <li><strong>double</strong> can hold a floating point number.
+        <p>Values are represented as `double`.</p>
+        <p>Sequences are represented as `double[]`.</p>
+    </li>
+    <li><strong>binary</strong> can hold a sequence of octets.
+        <p>Values are represented as `byte[]`.</p>
+        <p>Sequences are represented as `byte[][]`.</p>
+    </li>
+ </ul>
+
+ <p>Within templates an additional type <strong>any</strong> can occur. When
+ such a template is used to create a new SetElement, the type
+ of the element is initially reported as `any` (having no value).
+ When the value of such an element is first set, it will assume the type used.
+ </p>

+ <code>"com.sun.star.configuration.ConfigurationAccess"</code> and

+ </p>
+
+ <p>Using the first of these service specifiers requests a read-only view of

+ To reflect its <em>element role</em> as root of the view, it implements
+ service AccessRootElement.
+ </p>
+
+ <p>Using the second form requests an updatable view of the configuration.
+ The object that is created should implement service
+ ConfigurationUpdateAccess. To reflect its <em>element role</em>
+ which includes controlling updates for the whole view, it implements
+ service UpdateRootElement.
+ <BR />If the root element of the view is marked read-only (as indicated

+ </p>
+
+ <p>The arguments passed to

+ accessed starting from the returned object. Each element of the argument
+ sequence should be a com::sun::star::beans::PropertyValue
+ or a com::sun::star::beans::NamedValue,
+ so that the parameters can be identified by name rather than by position.
+ </p>
+
+ <p>What combinations of arguments are supported depends on the service name.
+ </p>
+
+ <p>With both of the standard service-specifiers above, an implementation must
+ accept a single argument named <code>nodepath</code> of type `string`.
+ This argument must contain the absolute path to an element of the
+ configuration. The view that is selected consists of the named element and
+ all its descendants.
+ </p>
+
+ <p>Other arguments can be used to control the behavior of the view. These
+ are different for different implementations. Whether and how they are used
+ may also depend on the configuration store and configuration that were
+ selected when the provider was created.
+ </p>
+
+ <p>An implementation must ignore unknown arguments.</p>
+
+ <p>Some parameters that are commonly supported are:</p>
+

+       <strong>Selecting data into a view:</strong>
+       <dl>
+         <dt><code>"nodepath"</code> : `string`</dt>
+         <dd>specifies the location of the view root in the configuration.</dd>
+         <dt><code>"depth"</code> : `short`</dt>
+         <dd>specifies that elements of the hierarchy that are more than the given
+          number of nesting levels away from the root need not be included in the

+         </dd>
+         <dt><code>"locale"</code> : com::sun::star::lang::Locale</dt>
+         <dd>specifies the locale for which localized values should be
+          retrieved.
+         </dd>
+       </dl>
+
+       <p><strong>Example:</strong> In the hierarchy

+          at some later time. If `FALSE`, the cache must operate in
+          <em>write-through</em> mode, where updates are written to persistent
+          storage at once - that is before
