The DetachableMap type


  • A Map with detachable entries. After retrieval, entries can be “detached”, removing them from the map, allowing any client to expire the key in the map. They are weak, and can be upgraded to a strong reference to the stored object.
  • A weak reference to an entry in a DetachableMap. This is a weak reference, if the entry is detached before it is upgraded, the entry can be gone.
