Description

This object is a "proxy repository" for all the objects:

Each GdaDict object can be saved to an XML file and loaded back in an efficient way; any GdaDict object can be assigned a GdaConnection object which tells it how to use a real connection to a data source.

The GdaDict object is responsible for the life management of all the objects it handles; see the GdaObject object for more information.

Details

GdaDict

typedef struct _GdaDict GdaDict;


gda_dict_new ()

GObject*    gda_dict_new                    (void);

Create a new GdaDict object.

Returns : the newly created object.

gda_dict_load_xml_file ()

gboolean    gda_dict_load_xml_file          (GdaDict *dict,
                                             const gchar *xmlfile,
                                             GError **error);

Loads an XML file which respects the Libgda DTD, and creates all the necessary objects that are defined within the XML file. During the creation of the other objects, all the normal signals are emitted.

If the GdaDict object already has some contents, then it is first of all destroyed (to return its state as when it was first created).

If an error occurs during loading then the GdaDict object is left as empty as when it is first created.

dict : a GdaDict object
xmlfile : the name of the file to which the XML will be written to
error : location to store error, or NULL
Returns : TRUE if loading was successfull and FALSE otherwise.

gda_dict_save_xml_file ()

gboolean    gda_dict_save_xml_file          (GdaDict *dict,
                                             const gchar *xmlfile,
                                             GError **error);

Saves the contents of a GdaDict object to a file which is given as argument.

dict : a GdaDict object
xmlfile : the name of the file to which the XML will be written to
error : location to store error, or NULL
Returns : TRUE if saving was successfull and FALSE otherwise.

gda_dict_declare_query ()

void        gda_dict_declare_query          (GdaDict *dict,
                                             GdaQuery *query);

Declares the existence of a new query to dict. All the GdaQuery objects MUST be declared to the corresponding GdaDict object for the library to work correctly. Once query has been declared, dict does not hold any reference to query. If dict must hold such a reference, then use gda_dict_assume_query().

This functions is called automatically from each gda_query_new* function, and it should not be necessary to call it except for classes extending the GdaQuery class.

dict : a GdaDict object
query : a GdaQuery object

gda_dict_assume_query ()

void        gda_dict_assume_query           (GdaDict *dict,
                                             GdaQuery *query);

Force dict to manage query: it will get a reference to it.

dict : a GdaDict object
query : a GdaQuery object

gda_dict_unassume_query ()

void        gda_dict_unassume_query         (GdaDict *dict,
                                             GdaQuery *query);

Forces dict to lose a reference it has on query

dict : a GdaDict object
query : a GdaQuery object

gda_dict_get_queries ()

GSList*     gda_dict_get_queries            (GdaDict *dict);

Get a list of all the non interdependant queries managed by dict (only queries with no parent query are listed)

dict : a GdaDict object
Returns : a new list of GdaQuery objects

gda_dict_get_query_by_xml_id ()

GdaQuery*   gda_dict_get_query_by_xml_id    (GdaDict *dict,
