In computer programming, a weak reference is a reference that does not protect the referenced object from collection by a garbage collector; unlike a strong reference. An object referenced only by weak references is considered unreachable (or weakly reachable) and so may be collected at any time. Some garbage-collected languages feature or support various levels of weak references, such as Java, C#, Python, Perl, and Lisp.

Famous quotes containing the words weak and/or reference:
“Mothers who are strong people, who can pursue a life of their own when it is time to let their children go, empower their children of either gender to feel free and whole. But weak women, women who feel and act like victims of something or other, may make their children feel responsible for taking care of them, and they can carry their children down with them.”
—Frank Pittman (20th century)
“In writing these Tales ... at long intervals, I have kept the book-unity always in mind ... with reference to its effect as part of a whole.”
—Edgar Allan Poe (1809–1849)
