Abstract:
A method for managing memory, comprising: maintaining a strong reference count for a first object; establishing a first reference from the first object to a second object; establishing a second reference from the second object to the first object, wherein the second reference is a weak reference that does not increase the strong reference count of the first object; detecting that the strong reference count of the first object has reached zero; in response to detecting that the strong reference count has reached zero, invoking a corresponding action.
