GdaVConnectionHubFunc ()

void                (*GdaVConnectionHubFunc)            (GdaConnection *cnc,
                                                         const gchar *ns,
                                                         gpointer data);


gda_vconnection_hub_add ()

gboolean            gda_vconnection_hub_add             (GdaVconnectionHub *hub,
                                                         GdaConnection *cnc,
                                                         const gchar *ns,
                                                         GError **error);

Make all the tables of cnc appear as tables (of the same name) in the hub connection. If the ns is not NULL, then within hub, the tables will be accessible using the 'ns.table_name' notation.

Within any instance of hub, there can be only one added connection where ns is NULL.

hub :

a GdaVconnectionHub connection

cnc :

a GdaConnection

ns :

a namespace, or NULL

error :

a place to store errors, or NULL

Returns :

TRUE if no error occurred

gda_vconnection_hub_remove ()

gboolean            gda_vconnection_hub_remove          (GdaVconnectionHub *hub,
                                                         GdaConnection *cnc,
                                                         GError **error);

Remove all the tables in hub representing cnc's tables.

hub :

a GdaVconnectionHub connection

cnc :

a GdaConnection

error :

a place to store errors, or NULL

Returns :

TRUE if no error occurred

gda_vconnection_hub_get_connection ()

GdaConnection *     gda_vconnection_hub_get_connection  (GdaVconnectionHub *hub,
                                                         const gchar *ns);

Find the GdaConnection object in hub associated to the ns name space

hub :

a GdaVconnectionHub connection

ns :

a name space, or NULL

Returns :

the GdaConnection, or NULL if no connection is associated to ns

gda_vconnection_hub_foreach ()

void                gda_vconnection_hub_foreach         (GdaVconnectionHub *hub,
                                                         GdaVConnectionHubFunc func,
                                                         gpointer data);

Call func for each GdaConnection represented in hub.

hub :

a GdaVconnectionHub connection

func :

a GdaVconnectionDataModelFunc function pointer

data :

data to pass to func calls
