GetOwner

Name

GetOwner -- Get object on which existence of object depends.

Description

Ownership hierarchies arrange themselves in a strict, single-rooted tree. The top-level node of an ownership hierarchy typically returns nil as its owner. If an object is regarded merely as one part of another object defined as its owner, then copying or dropping the owner object should copy or drop the member object as well. Owner and member are neutral terms for a generic relationship sometimes called parent vs. child, but it is up to a particular object type to define specifically what it means by a getOwner relationship.

Protocols adopted by GetOwner

None

Methods

Phase: Using

- getOwner
The getOwner message returns another object which is considered as the owner of an initial object. What is considered as an owner depends on its specific object type, but might be a larger object of which the local object is a part, or an object that has exclusive control over the local object. The principal constraint established by an ownership structure is that a given object can have only a single other object as its unambiguous owner.
