Overview

This class is abstract.

Common superclass for weak atomic references.

A weak atom does not keep its current value alive. Its value becomes nil after garbage collection when no strong references remain. Collection timing is controlled by the garbage collector. In-flight operations may temporarily retain values they observe. Updates are serialized even when collection changes the observed value.

Constructor Details

#initialize(value = nil, compare_by_identity: false) ⇒ WeakAtom
