    • WriteThroughEntry

      protected WriteThroughEntry(K k, V v)
      Creates a write-through entry backed by the supplied key and value.
      Parameters:
      k - the entry key
      v - the entry value

  • Method Details

    • setValue

      public V setValue(V value)
      Set our entry's value and writes it through to the map. The value to return is somewhat arbitrary: since a WriteThroughEntry does not necessarily track asynchronous changes, the most recent "previous" value could be different from what we return (or could even have been removed in which case the put will re-establish). We do not and cannot guarantee more.
