#### `lru_cache` Technical Details { #lru-cache-technical-details }

`@lru_cache` modifies the function it decorates to return the same value that was returned the first time, instead of computing it again, executing the code of the function every time.

### Modifier le code { #edit-it }

C'est un programme très simple.

Mais maintenant imaginez que vous l'écriviez de zéro.

À un certain moment, vous auriez commencé la définition de la fonction, vous aviez les paramètres prêts ...

    return Maps.equalsImpl(this, object);
  }

  @Override
  public int hashCode() {
    // not caching hash code since it could change if map values are mutable
    // in a way that modifies their hash codes
    return entrySet().hashCode();
  }

  @Override
  public String toString() {
    return Maps.toStringImpl(this);
  }

		}
	}
}

func TestWriterTime(t *testing.T) {
	var buf bytes.Buffer
	h := &FileHeader{
		Name:     "test.txt",
		Modified: time.Date(2017, 10, 31, 21, 11, 57, 0, timeZone(-7*time.Hour)),
	}
	w := NewWriter(&buf)
	if _, err := w.CreateHeader(h); err != nil {
		t.Fatalf("unexpected CreateHeader error: %v", err)
	}

#### Détails techniques de `lru_cache` { #lru-cache-technical-details }

`@lru_cache` modifie la fonction qu'il décore pour renvoyer la même valeur que celle qui a été retournée la première fois, au lieu de la recalculer en exécutant le code de la fonction à chaque fois.

 * 4648. Decoding rejects characters in the wrong case, though padding is optional. To modify
 * encoding and decoding behavior, use configuration methods to obtain a new encoding with modified
 * behavior:
 *
 * {@snippet :
 * BaseEncoding.base16().lowerCase().decode("deadbeef");
 * }
 *
 * <p>Warning: BaseEncoding instances are immutable. Invoking a configuration method has no effect
