Description

Details

struct AtkRelationSet

struct AtkRelationSet;

The AtkRelationSet structure should not be accessed directly.


atk_relation_set_new ()

AtkRelationSet* atk_relation_set_new        (void);

Creates a new empty relation set.

Returns :

a new AtkRelationSet


atk_relation_set_contains ()

gboolean    atk_relation_set_contains       (AtkRelationSet *set,
                                             AtkRelationType relationship);

Determines whether the relation set contains a relation that matches the specified type.

set :

an AtkRelationSet

relationship :

an AtkRelationType

Returns :

TRUE if relationship is the relationship type of a relation in set, FALSE otherwise


atk_relation_set_remove ()

void        atk_relation_set_remove         (AtkRelationSet *set,
                                             AtkRelation *relation);

Removes a relation from the relation set. This function unref's the AtkRelation so it will be deleted unless there is another reference to it.

set :

an AtkRelationSet

relation :

an AtkRelation


atk_relation_set_add ()

void        atk_relation_set_add            (AtkRelationSet *set,
                                             AtkRelation *relation);

Add a new relation to the current relation set if it is not already present. This function ref's the AtkRelation so the caller of this function should unref it to ensure that it will be destroyed when the AtkRelationSet is destroyed.

set :

an AtkRelationSet

relation :

an AtkRelation


atk_relation_set_get_n_relations ()

gint        atk_relation_set_get_n_relations
                                            (AtkRelationSet *set);

Determines the number of relations in a relation set.

set :

an AtkRelationSet

Returns :

an integer representing the number of relations in the set.


atk_relation_set_get_relation ()

AtkRelation* atk_relation_set_get_relation  (AtkRelationSet *set,
                                             gint i);

Determines the relation at the specified position in the relation set.

set :

an AtkRelationSet

i :

a gint representing a position in the set, starting from 0.

Returns :

a AtkRelation, which is the relation at position i in the set.


atk_relation_set_get_relation_by_type ()

AtkRelation* atk_relation_set_get_relation_by_type
                                            (AtkRelationSet *set,
                                             AtkRelationType relationship);

Finds a relation that matches the specified type.

set :

an AtkRelationSet

relationship :

an AtkRelationType

Returns :

an AtkRelation, which is a relation matching the specified type.
