Description:
All known sub-classes:
Namespace: Gda
Package: libgda-6.0
Content:
Properties:
- public string description { owned get; set; }
- public void* holders { construct; }
- public string id { owned get; set; }
- public string name { owned get; set; }
- public bool validate_changes { get; set; }
Defines if the "validate-set" signal gets emitted when any holder in the data set changes.
Static methods:
- public static Quark error_quark ()
Creation methods:
- public Set (SList<Holder> holders)
Creates a new Set object, and populates it with the list given as argument.
- public Set.from_spec_node (unowned Node* xml_spec) throws Error
Creates a new Set object from the
xml_spec
specifications - public Set.from_spec_string (string xml_spec) throws Error
Creates a new Set object from the
xml_spec
specifications - public Set.read_only (SList<Holder> holders)
Methods:
- public bool add_holder (Holder holder)
Adds
holder
to the list of holders managed within this. - public Set copy ()
Creates a new Set object, copy of this
- public unowned SetGroup get_group (Holder holder)
- public unowned SList<SetGroup> get_groups ()
- public unowned Holder get_holder (string holder_id)
Finds a Holder using its ID
- public unowned Value? get_holder_value (string holder_id)
Get the value of the Holder which ID is
holder_id
- public unowned SList<Holder> get_holders ()
- public unowned SetNode get_node (Holder holder)
Finds a SetNode holding information for
holder
, don't modify the returned structure - public unowned SList<SetNode> get_nodes ()
- public unowned Holder get_nth_holder (int pos)
Finds a Holder using its position
- public unowned SetSource get_source (Holder holder)
- public unowned SetSource get_source_for_model (DataModel model)
Finds the SetSource structure used in this for which
model
is a the data model (the returned structure should not be modified). - public unowned SList<SetSource> get_sources ()
- public bool is_valid () throws Error
This method tells if all this's 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.
- public void merge_with_set (Set set_to_merge)
Add to this all the holders of
set_to_merge
. - public void remove_holder (Holder holder)
Removes a Holder from the list of holders managed by this
- public void replace_source_model (SetSource source, DataModel model)
Replaces
source
->data_model withmodel
, which must have the same characteristics assource
->data_model (same column types)
Signals:
- public virtual signal void holder_attr_changed (Holder holder, string attr_name, Value attr_value)
Gets emitted when an attribute for any of the Holder objects managed by
set
has changed - public virtual signal void holder_changed (Holder holder)
- public virtual signal void holder_type_set (Holder holder)
Gets emitted when
holder
inset
has its type finally set, in case it wasGDA_TYPE_NULL
- public virtual signal void public_data_changed ()
- public virtual signal void source_model_changed (void* source)
Gets emitted when the data model in
source
has changed - public virtual signal Error validate_holder_change (Holder holder, Value new_value)
Gets emitted when a Holder's in
set
is going to change its value. - public virtual signal Error validate_set ()
Gets emitted when is_valid is called, use this signal to control which combination of values
set
's holder can have (for example to implement some business rules)
