Detailed Description
Container for several values.
The Gda::Set object is a container for several values (as Gda::Holder objects), which also offers different classifications of the group of GdaHolder values (see get_node(), get_source() or get_group()).
It is possible to control the values a Gda::Holder can have in the Gda::Set by connecting to the signal_before_holder_change() signal.

void Gnome::Gda::Set::add_holder | ( | const Glib::RefPtr< Holder >& | holder | ) |
Adds holder to the list of holders managed within set.
NOTE: if set already has a Gda::Holder 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).
- Parameters
-
holder A Gda::Holder object.
- Returns
true
if holder has been added to set (andfalse
if it has not been added because there is another Gda::Holder with the same ID).
void Gnome::Gda::Set::add_holder | ( | const Glib::ustring & | id, |
const ValueType & | value | ||
) |
Add a holder.
Convenience method to add a holder with value
- Parameters
-
id Name of the holder value Value of the holder
void Gnome::Gda::Set::add_holder_as_value | ( | const Glib::ustring & | id, |
const Gda::Value& | value | ||
) |
Add a holder.
Convenience method to add a holder with value
- Parameters
-
id Name of the holder value Value of the holder

|
static |
Glib::RefPtr<Holder> Gnome::Gda::Set::get_holder | ( | const Glib::ustring & | holder_id | ) |
Finds a Gda::Holder using its ID.
- Parameters
-
holder_id The ID of the requested value holder.
- Returns
- The requested Gda::Holder or
0
.
Glib::RefPtr<const Holder> Gnome::Gda::Set::get_holder | ( | const Glib::ustring & | holder_id | ) | const |
Finds a Gda::Holder using its ID.
- Parameters
-
holder_id The ID of the requested value holder.
- Returns
- The requested Gda::Holder or
0
.
Value Gnome::Gda::Set::get_holder_value | ( | const Glib::ustring & | holder_id | ) | const |
Get the value of the Gda::Holder which ID is holder_id.
- Parameters
-
holder_id The ID of the holder to set the value.
- Returns
- The requested GValue, or
0
(see Gda::Holder::get_value()).
|

GdaSet* Gnome::Gda::Set::gobj_copy | ( | ) |
Provides access to the underlying C instance. The caller is responsible for unrefing it. Use when directly setting fields in structs.
bool Gnome::Gda::Set::is_valid | ( | ) | const |
This method tells if all set's Gda::Holder 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.
- Returns
true
if the set is valid.
void Gnome::Gda::Set::merge_with_set | ( | const Glib::RefPtr< Set >& | set_to_merge | ) |
Add to set all the holders of set_to_merge.
- Note
- only the Gda::Holder of set_to_merge for which no holder in set has the same ID are merged
- all the Gda::Holder merged in set are still used by set_to_merge.
- Parameters
-
set_to_merge A Gda::Set object.
