Örneğin, şöyle bir fonksiyonunuz varsa:

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

programınız şu şekilde çalışabilir:

```mermaid
sequenceDiagram

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

        () -> {
          AbstractFuture<String> future = setFutureFuture.get();
          setFutureSetSuccess.set(currentFuture.get().setFuture(future));
          setFutureCompletionSuccess.set(future.set("hello-async-world"));
          awaitUnchecked(barrier);
        };
    Set<Object> finalResults = Collections.synchronizedSet(Sets.newIdentityHashSet());
    Runnable collectResultsRunnable =
        () -> {

Наприклад, якщо у вас є функція:

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

ваша програма може виконуватись так:

```mermaid
sequenceDiagram

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

            // Internal projects are not all plugins, so make sure the check is available
            // we are not doing this for this project itself to avoid jar hell with itself
            project.getDependencies().add(JDK_JAR_HELL_CONFIG_NAME, project.project(LIBS_ELASTICSEARCH_CORE_PROJECT_PATH));
        }

Por ejemplo, si tienes una función:

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

tu programa podría ejecutarse así:

```mermaid
sequenceDiagram

participant code as Código
participant function as say_hi()
participant execute as Ejecutar función

                .make();
        try {
            dynamicType.toJar(targetFile(projectRoot));
        } catch (IOException e) {
            e.printStackTrace();
            fail("Cannot setup jdk jar hell classpath");
        }
    }

    private static File targetFile(File projectRoot) {
        File targetFile = new File(
                projectRoot,

        }
    }

    private static List<String> filesFromMerge(String commit) throws IOException, InterruptedException, ExecutionException {
        // Git revision range syntax is part of git, not the shell; pass as-is.
        return getStdoutLines(new String[] {"git", "diff", "--name-only", commit + "^1.." + commit});
    }

따라서 아래의 함수는 인자 조합마다 한 번씩 실행됩니다. 그리고 각각의 인자 조합에 대해 반환된 값은, 함수가 정확히 같은 인자 조합으로 호출될 때마다 반복해서 사용됩니다.

예를 들어 다음 함수가 있다면:

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

프로그램은 다음과 같이 실행될 수 있습니다:

```mermaid
sequenceDiagram

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

`@lru_cache` 會修改它所裝飾的函式，使其回傳第一次回傳的相同值，而不是每次都重新計算、執行函式碼。

因此，被裝飾的函式對於每組參數組合只會執行一次。之後，凡是以完全相同參數組合呼叫時，都會重複使用先前對應的回傳值。

例如，如果你有一個函式：

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

你的程式可能會這樣執行：

```mermaid
sequenceDiagram

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

					n := 0
					var latency int64
					managers := grid.Managers
					hosts := grid.Hosts
					req := testRequest{
						Num:    rng.Int(),
						String: "hello",
					}
					for pb.Next() {
						// Pick a random manager.
						src, dst := rng.Intn(len(managers)), rng.Intn(len(managers))
						if src == dst {
							dst = (dst + 1) % len(managers)
						}
