Description:

weak

Weak Referenced Collection Classes #
WeakHashMap, WeakHashSet, WeakList, and WeakReferenceQueue implemented with [WeakReference] and [Finalizer]
Features #


[WeakHashMap]: A hash-table based implementation of [Map] with weak referenced keys.
An entry in this weak hash map will be automatically removed when its key
is garbage collected.


[WeakHashSet]: A hash-table based implementation of [Set] with weak referenced elements.
An element in this weak hash set will be automatically removed when the element is
garbage collected.


[WeakList]: An ordered [List] implementation with weak referenced elements. An element
in this weak list will be automatically nullified when the element is garbage collected.


[WeakReferenceQueue]: A queue that maintains payload of its associated weak referenced
target. The payload registered in this class will be appended into the queue when its
associated target is garbage collected. Then you can call [WeakReferenceQueue.poll] method
to retrieve back the payloads from the queue and do some after-garbage-collected process.
