module com { module sun { module star { module configuration {
//=============================================================================
/** manages one, or more, complete sets of configuration data for
administrative puposes and serves as a factory for objects that
provide access to subsets of these shared configurations.
<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 users' 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
<type scope="com::sun::star::lang">ServiceManager</type>. The arguments passed to
<member scope="com::sun::star::lang">XMultiComponentFactory::createInstanceWithContextAndArguments()</member>
select the configuration data source. They may also define the scope of
administrable data or contain credentials to be used to authorize the
administrative access. Missing parameters may be filled in
from the context or the environment.
</p>
@see com::sun::star::configuration::ConfigurationProvider
Offers the same services and creates the same accessor objects as this
service, but accesses the personal configuration.
<p>A <type> ConfigurationProvider</type> provides access to the personal
layer of configuration data of the current user context. It should in
most cases be used when <em>using</em> the configuration data, although
for most contexts a <type>AdministrationProvider</type> can be used as
a drop-in replacement.
</p>
*/
service AdministrationProvider
{
/** allows creating access objects for specific views such as subsets and fragments
of the configuration.
<p>The parameter <var>aServiceSpecifier</var> passed to
<member scope="com::sun::star::lang">XMultiServiceFactory::createInstanceWithArguments()</member>
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 <type>ConfigurationAccess</type>.
To reflect its <em>element role</em> as root of the view, it implements
service <type>AccessRootElement</type>.
</p>
<p>Using the second form requests an updatable view of the configuration.
The object that is created should implement service
<type>ConfigurationUpdateAccess</type>. To reflect its <em>element role</em>
which includes controlling updates for the whole view, it implements
service <type>UpdateRootElement</type>.
<BR />If the root element of the view is marked read-only (as indicated
by <const scope="com::sun::star::beans">PropertyAttributes::READONLY</const>),
the implementation may either raise an exception or return a (read-only)
<type>ConfigurationAccess</type>/<type>AccessRootElement</type> instead.
</p>
<p>The arguments passed to
<member scope="com::sun::star::lang">XMultiServiceFactory::createInstanceWithArguments()</member>
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 <type scope="com::sun::star::beans">PropertyValue</type>
or a <type scope="com::sun::star::beans">NamedValue</type>,
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 <atom>string</atom>.
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 decendants. The administrative entity is the default for the
<type>AdministrationProvider</type>. 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
<type>ConfigurationProvider</type>.
</p>
<p>One notable difference exists for parameter <code>"locale"</code>. For a
<type>ConfigurationProvider</type> 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 <type>SetAccess</type> using the language names as accessors.
This also allows targetted setting of values for selected locales.
This behavior can be requested explicitly by specifing a special argument
value <code>locale = "*"</code>.
</p>
<p><member scope="com::sun::star::lang">XMultiServiceFactory::createInstance()</member>
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
<member scope="com::sun::star::lang">XMultiServiceFactory::createInstanceWithArguments()</member>
had been called using an empty sequence of arguments.
</p>
*/
interface com::sun::star::lang::XMultiServiceFactory;
/** allows controlling or observing the lifetime of the configuration.
<p>The owner of the provider may dispose of this object
using <member scope="com::sun::star::lang">XComponent::dispose()</member>.
</p>
<p>Views created by the provider generally refer to data that is managed by
the provider. Therefore, disposing of the provider will cause all objects
belonging to these views to be disposed of as well. This does not apply to
<em>snapshot</em> views that have their own copy of the data, if available.
