RelationRef
public struct RelationRef : RelationProtocol, GWeakCapturing
An AtkRelation describes a relation between an object and one or more other objects. The actual relations that an object has with other objects are defined as an AtkRelationSet, which is a set of AtkRelations.
The RelationRef
type acts as a lightweight Swift reference to an underlying AtkRelation
instance.
It exposes methods that can operate on this data type through RelationProtocol
conformance.
Use RelationRef
only as an unowned
reference to an existing AtkRelation
instance.
-
Untyped pointer to the underlying `AtkRelation` instance.
For type-safe access, use the generated, typed pointer
relation_ptr
property instead.Declaration
