Method Detail

setValue

public V setValue(V value)

Set our entry's value and write through to the map. The value to return is somewhat arbitrary here. 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.
