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:
“Power corrupts ... when the weak band together in order to ruin the strong, but not before. The will to power ... far from being a characteristic of the strong, is, like envy and greed, among the vices of the weak, and possibly even their most dangerous one.”
—Hannah Arendt (1906–1975)
“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)
