弱引用 Weak reference

(重定向自Strong reference)

在计算机进程设计中,弱引用与强引用相对,是指不能确保其引用的对象不会被垃圾回收器回收的引用。一个对象若只被弱引用所引用,则被认为是不可访问(或弱可访问)的,并因此可能在任何时刻被回收。一些配有垃圾回收机制的语言,如Java、C#、Python、Perl、Lisp等都在不同程度上支持弱引用。

Weak reference 弱引用

(重定向自Strong reference)

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 – meaning "every chain of references that reaches the object includes at least one weak reference as a link" – is considered weakly reachable, and can be treated as unreachable 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.
