## 12. Future Enhancements

1. **Directory Leases**: Extend lease support for directories
2. **Lease Key Persistence**: Save lease keys for reconnection

Este código é algo que você pode realmente usar na sua aplicação, salvar os hashes das senhas no seu banco de dados, etc.

Vamos começar de onde paramos no capítulo anterior e incrementá-lo.

## Sobre o JWT

JWT significa "JSON Web Tokens".

É um padrão para codificar um objeto JSON em uma string longa e densa sem espaços. Ele se parece com isso:

```

        CacheBuilder.newBuilder()
            .removalListener(removalListener)
            .expireAfterWrite(10, MILLISECONDS)
            .ticker(ticker)
            .build(loader);

    // Increment 100 times
    for (int i = 0; i < 100; ++i) {
      cache.getUnchecked(10).incrementAndGet();
      ticker.advance(1, MILLISECONDS);
    }

    assertEquals(evictionCount.get() + 1, applyCount.get());

         */
        public synchronized void updateState(int newState) {
            this.leaseState = newState;
            this.lastAccessTime = System.currentTimeMillis();
        }

        /**
         * Increment the epoch value
         */
        public synchronized void incrementEpoch() {
            this.epoch++;
        }

        /**
         * Check if lease has read caching
         *

   * both IPv4 and IPv6 addresses.
   *
   * @param address the InetAddress to increment
   * @return a new InetAddress that is one more than the passed in address
   * @throws IllegalArgumentException if InetAddress is at the end of its range
   * @since 10.0
   */
  public static InetAddress increment(InetAddress address) {
    byte[] addr = address.getAddress();
    int i = addr.length - 1;

        assertNull(crawlingConfigHelper.getCrawlingConfig("W123"));
    }

    public void test_store_counterIncrement() {
        final String sessionId = "testSession";

        // Test counter increment
        String sessionCountId1 = crawlingConfigHelper.store(sessionId, crawlingConfigHelper.getCrawlingConfig("W1"));
        assertEquals("testSession-1", sessionCountId1);
