Log:
2008-03-06  Vivien Malerba <malerba gnome-db org>

        * tests/value-holders/check_statement.c:
        * tests/parser/check_parser.c: don't crash on missing providers
        * tests/data-models/check_virtual.c: fixed a compilation problem
        * tests/data-models/check_data_proxy.c:
        * libgda/gda-data-proxy.c:
        * libgda/gda-server-operation.c:
        * libgda/gda-data-model-array.[ch]: make gda_data_model_array_copy_model() return a
        GdaDataModelArray instead of a GdaDataModel (fixes bug #519778)
        * doc/C/tmpl/gda-data-model-iter.sgml: added instructions on how to use a
        GdaDataModelIter (fixes bug #519769)

        * libgda/gda-data-model-iter.[ch]: removed gda_data_model_iter_new() as it is better to use
        gda_data_model_create_iter()
        * libgda/gda-data-access-wrapper.c:
        * libgda/sqlite/virtual/gda-vprovider-data-model.c:

        * tests/meta-store/data_columns.csv:
        * tests/meta-store/common.c: adaptations to the GdaMetaStore's internal schema changes, make the
        test pass again
        * libgda/gda-meta-struct.[ch]: converted to a GObject, and added some new features

 GdaDataModelIter

+Data model iterator
 
 <!-- ##### SECTION Long_Description ##### -->
 <para>
-
+  A #GdaDataModelIter object is used to iterate through the rows of a #GdaDataModel. If the data model is accessible
+  in a random access way then any number of #GdaDataModelIter objects can be created on the same data model, and
+  if the data model only supports a cursor based access then only one #GdaDataModelIter can be created. In any case
+  creating a #GdaDataModelIter should be done using the gda_data_model_create_iter() method. Note that if 
+  the data model only supports a cursor based access, then calling this method several times will always return
+  the same #GdaDataModelIter, but with its reference count increased by 1 (so you should call g_object_unref() when
+  finished with it).
+</para>
+<para>
+  When a #GdaDataModelIter is valid (that is when it points to an existing row in the data model it iterates through),
+  the individual values (corresponding to each column of the data model, at the pointer row) can be accessed 
+  using the gda_data_model_iter_get_value_at() or gda_data_model_iter_get_value_for_field() methods
+  (or in the same way #GdaSet's values are accessed as #GdaDataModelIter inherits the #GdaSet).
+</para>
+<para>
+  Right after being created, a #GdaDataModelIter is invalid (does not point to any row of its data model). To read the
+  first row of the data model, use the gda_data_model_iter_move_next() method. Calling this method several times will
+  move the iterator forward, up to when the data model has no more rows and the #GdaDataModelIter will be declared invalid
+  (and gda_data_model_iter_move_next() has returned FALSE). Note that at this point, the number of rows in the data
+  model will be known.
+</para>
+<para>
+  If the data model supports it, a #GdaDataModelIter can be moved backwards using the gda_data_model_iter_move_prev()
+  method. However if the iterator is invalid, moving backwards will not be possible (on the contrary to 
+  gda_data_model_iter_move_next() which moves to the first row).
+</para>
+<para>
+  The gda_data_model_iter_set_at_row() method, if the iterator can be moved both forward and backwards, can move the 
+  iterator to a specific row (sometimes faster than moving it forward or backwards a number of times).
