Enclosing class:
References
static final class References.LookupKeyReference<E> extends Object implements References.InternalReference<E>
A short-lived adapter used for looking up an entry in the cache where the keys are weakly held. This References.InternalReference implementation is not suitable for storing in the cache as the key is strongly held.

    • get

      public E get()
      Description copied from interface: References.InternalReference
      Returns this reference object's referent. If this reference object has been cleared, either by the program or by the garbage collector, then this method returns null.

    • getKeyReference

      public Object getKeyReference()
      Description copied from interface: References.InternalReference

      getKeyReference in interface References.InternalReference<E>
      Returns:
      the key that is associated to the cached entry
