The parameter aServiceSpecifier passed to ::com::sun::star::lang::XMultiServiceFactory::createInstanceWithArguments supports at least the service specifier "com.sun.star.ucb.HierarchyDataReadAccess", which will create a read-only view to the data. The object that is created implements the service HierarchyDataReadAccess.

Optionally the factory may support writable views. A writable view is requested by passing the service specifier "com.sun.star.ucb.HierarchyDataReadWriteAccess" to ::com::sun::star::lang::XMultiServiceFactory::createInstanceWithArguments The object that is created implements the service HierarchyDataReadWriteAccess.

The arguments passed to ::com::sun::star::lang::XMultiServiceFactory::createInstanceWithArguments in parameter aArguments specify the view of the data 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, so that the parameters can be identified by name rather than by position.

With both of the standard service specifiers above, an implementation must accept a property named nodepath of type string. This property must contain the absolute path to an element of the data. The view that is selected consists of the named element and all its decendants. A path consists of segments that are separated by a single slash ('/'). There is neither a leading nor a trailing slash allowed. The root of the hierarchy data always has an empty path. Refer to HierarchyDataReadAccess for more informtion on hierarchical names.

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.

An implementation must ignore unknown arguments.

The implementation of ::com::sun::star::lang::XMultiServiceFactory::createInstance must behave exactly as if ::com::sun::star::lang::XMultiServiceFactory::createInstanceWithArguments were called passing one single property named nodepath where the property value is an empty string. Thus it always creates a view to the root of the hierarchy data.
