gda_set_new ()

GdaSet *
gda_set_new (GSList *holders);

Creates a new GdaSet object, and populates it with the list given as argument. The list can then be freed as it is copied. All the value holders in holders are referenced counted and modified, so they should not be used anymore afterwards.

gda_set_new_read_only ()

GdaSet *
gda_set_new_read_only (GSList *holders);

Creates a new GdaSet like gda_set_new(), but does not allow modifications to any of the GdaHolder object in holders . This function is used for Libgda's database providers' implementation.

Since: 4.2

gda_set_copy ()

GdaSet *
gda_set_copy (GdaSet *set);

Creates a new GdaSet object, copy of set

gda_set_new_inline ()

GdaSet *
gda_set_new_inline (gint nb,

Creates a new GdaSet containing holders defined by each triplet in ... For each triplet (id, Glib type and value), the value must be of the correct type (gchar * if type is G_STRING, ...)

Note that this function is a utility function and that only a limited set of types are supported. Trying to use an unsupported type will result in a warning, and the returned value holder holding a safe default value.

gda_set_new_from_spec_string ()

GdaSet *
gda_set_new_from_spec_string (const gchar *xml_spec,
                              GError **error);

gboolean
gda_set_is_valid (GdaSet *set,
                  GError **error);

This method tells if all set 's GdaHolder objects are valid, and if they represent a valid combination of values, as defined by rules external to Libgda: the "validate-set" signal is emitted and if none of the signal handlers return an error, then the returned value is TRUE, otherwise the return value is FALSE as soon as a signal handler returns an error.

gda_set_get_holder_value ()

const GValue *
gda_set_get_holder_value (GdaSet *set,
                          const gchar *holder_id);

                          ...);

Set the value of the GdaHolder which ID is holder_id to a specified value

[skip]

gda_set_get_holder ()

GdaHolder *
gda_set_get_holder (GdaSet *set,
                    const gchar *holder_id);

NOTE: if set already has a GdaHolder with the same ID as holder , then holder will not be added to the set (even if holder 's type or value is not the same as the one already in set ).

gda_set_remove_holder ()

void
gda_set_remove_holder (GdaSet *set,
                       GdaHolder *holder);

gda_set_replace_source_model (GdaSet *set,
                              GdaSetSource *source,
                              GdaDataModel *model);

Replaces source->data_model with model , which must have the same characteristics as source->data_model (same column types)

Also for each GdaHolder for which source->data_model is a source model, this method calls gda_holder_set_source_model() with model to replace the source by the new model

Since: 4.2

                   GdaHolder *holder);

Finds a GdaSetGroup which lists a GdaSetNode containing holder , don't modify the returned structure.
