class
WeakHashMap[K, E](val override underlying : java.util.WeakHashMap[K, E])
extends MapWrapper[K, E]A map that is backed by a Java weak hash map, whose keys are maintained as weak references.
Because keys are weak references, the garbage collector can collect them if they are not referred to elsewhere.
Useful for implementing caches.
