#### `HeroUpdate` - el *modelo de datos* para actualizar un héroe { #heroupdate-the-data-model-to-update-a-hero }

No teníamos una forma de **actualizar un héroe** en la versión anterior de la aplicación, pero ahora con **múltiples modelos**, podemos hacerlo. 🎉

   * addresses, the output follows <a href="http://tools.ietf.org/html/rfc5952">RFC 5952</a> section
   * 4. The main difference is that this method uses "::" for zero compression, while Java's version
   * uses the uncompressed form (except on Android, where the zero compression is also done). The
   * other difference is that this method outputs any scope ID in the format that it was provided at

    // Delegates to the fast (unsafe) version or the fallback.
    return byteArray.getLongLittleEndian(input, offset);
  }

  /**
   * Similar to load64, but allows offset + 8 > input.length, padding the result with zeroes. This
   * has to explicitly reverse the order of the bytes as it packs them into the result which makes
   * it slower than the native version.
   *
   * @param input the input bytes

 *
 * When merging `releaseX` branch into `master`, we should only use the release note from the `master` branch,
 * but sometimes changes on release notes.md was brought to master and merged unnoticed,
 * e.g https://github.com/gradle/gradle/pull/25825
 *
 * This script is to check if there is any merge commit that brings changes from release branch to master.
 *
 * Usage (Java 11+ single-file source execution):

* **Swagger UI**: served at `/docs`.
    * You can set its URL with the parameter `docs_url`.
    * You can disable it by setting `docs_url=None`.
* **ReDoc**: served at `/redoc`.
    * You can set its URL with the parameter `redoc_url`.
    * You can disable it by setting `redoc_url=None`.

For example, to set Swagger UI to be served at `/documentation` and disable ReDoc:

   * it is returned directly. Otherwise, a new array of size {@code minLength + padding} is
   * returned, containing the values of {@code array}, and zeroes in the remaining places.
   *
   * @param array the source array
   * @param minLength the minimum length the returned array must guarantee
   * @param padding an extra amount to "grow" the array by if growth is necessary

    assertCrc(0, new byte[0]);

  public void testZeros() {
    // Test 32 byte array of 0x00.
    byte[] zeros = new byte[32];
    assertCrc(0x8a9136aa, zeros);

  public void testZeros100() {
    // Test 100 byte array of 0x00.
    byte[] zeros = new byte[100];
    assertCrc(0x07cb9ff6, zeros);
  }

  public void testFull() {
    // Test 32 byte array of 0xFF.
    byte[] fulls = new byte[32];

     * and will be merged, but overlapping ranges will cause an exception when {@link #build()} is
     * called.

  public void testToUriStringIPv6() {

Aqui, usamos a dependência `SessionDep` (uma `Session`) para adicionar o novo `Hero` à instância `Session`, fazer commit das alterações no banco de dados, atualizar os dados no `hero` e então retorná-lo.

### Ler Heroes { #read-heroes }

Podemos **ler** `Hero`s do banco de dados usando um `select()`. Podemos incluir um `limit` e `offset` para paginar os resultados.
