For example, if you have a function:

```Python
@lru_cache
def say_hi(name: str, salutation: str = "Ms."):
    return f"Hello {salutation} {name}"
```

your program could execute like this:

```mermaid
sequenceDiagram

participant code as Code
participant function as say_hi()
participant execute as Execute function

 * </ul>
 * <p>
 * <strong>Usage Example:</strong>
 * </p>
 * <pre>
 * CachedCipher cipher = new CachedCipher();
 * cipher.setKey("mySecretKey");
 *
 * // Encrypt text
 * String encrypted = cipher.encryptText("Hello World");
 *
 * // Decrypt text
 * String decrypted = cipher.decryptText(encrypted);
 *
 * // For AES encryption
 * CachedCipher aesCipher = new CachedCipher();
 * aesCipher.setAlgorithm("AES");

Por exemplo, se você tiver uma função:

```Python
@lru_cache
def say_hi(name: str, salutation: str = "Ms."):
    return f"Hello {salutation} {name}"
```

seu programa poderia executar assim:

```mermaid
sequenceDiagram

participant code as Code
participant function as say_hi()
participant execute as Execute function

因此，下面的函数会针对每个参数组合执行一次。然后，当以完全相同的参数组合调用该函数时，将重复使用该参数组合先前返回的值。

例如，如果你有一个函数：

```Python
@lru_cache
def say_hi(name: str, salutation: str = "Ms."):
    return f"Hello {salutation} {name}"
```

你的程序可能会像这样执行：

```mermaid
sequenceDiagram

participant code as Code
participant function as say_hi()
participant execute as Execute function

   * that tests equivalence using their lengths:
   *
   * {@snippet :
   * equiv.wrap("a").equals(equiv.wrap("b")) // true
   * equiv.wrap("a").equals(equiv.wrap("hello")) // false
   * }
   *
   * <p>Note in particular that an equivalence wrapper is never equal to the object it wraps.
   *
   * {@snippet :
   * equiv.wrap(obj).equals(obj) // always false
