Expand description

Trait containing all RelationSet methods.

§Implementors

RelationSet

Provided Methods§

Source

fn add(&self, relation: &impl IsA<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.

§`relation`

an Relation

Source

fn add_relation_by_type( &self, relationship: RelationType, target: &impl IsA<Object>, )

Add a new relation of the specified type with the specified target to the current relation set if the relation set does not contain a relation of that type. If it is does contain a relation of that typea the target is added to the relation.
