 * <p>Or equivalently,

 * // In real life this would come from a command-line flag or config file
 * String spec = "maximumSize=10000,expireAfterWrite=10m";
 *
 * LoadingCache<Key, Graph> graphs = CacheBuilder.from(spec)
 *     .removalListener(MY_LISTENER)
 *     .build(
 *         new CacheLoader<Key, Graph>() {
 *           public Graph load(Key key) throws AnyException {

 * <p>The returned cache is implemented as a hash table with similar performance characteristics to
 * {@link ConcurrentHashMap}. It implements all optional operations of the {@link LoadingCache} and
 * {@link Cache} interfaces. The {@code asMap} view (and its collection views) have <i>weakly
 * consistent iterators</i>. This means that they are safe for concurrent use, but if other threads
 * modify the cache after the iterator is created, it is undefined which of these changes, if any,
 * are reflected in that iterator. These iterators never throw {@link
 * ConcurrentModificationException}.
 *
 * <p><b>Note:</b> by default, the returned cache uses equality comparisons (the {@link
 * Object#equals equals} method) to determine equality for keys or values. However, if {@link
