}
            item = newItem;
        }

        /**
         * Writes a synonym item to the temporary file.
         * If the item is being updated, it writes the new version.
         *
         * @param oldItem The original item from the dictionary.
         * @return The written item, or null if the item was deleted.

```kotlin
cache.delete()
```
 
## Pruning the Cache

Pruning the entire Cache to clear space temporarily can be done using evictAll.

```kotlin
cache.evictAll()
```

Removing individual items can be done using the urls iterator.
This would be typical after a user initiates a force refresh by a pull to refresh type action.

```java
    val urlIterator = cache.urls()
    while (urlIterator.hasNext()) {

												<la:message key="labels.profile" />
											</la:link>
										</c:if>
										<c:if test="${adminUser == true}">
											<la:link href="/admin" styleClass="dropdown-item">
												<la:message key="labels.administration" />
											</la:link>
										</c:if>
										<la:link href="/logout/" styleClass="dropdown-item">
											<la:message key="labels.logout" />

												<la:message key="labels.profile" />
											</la:link>
										</c:if>
										<c:if test="${adminUser == true}">
											<la:link href="/admin" styleClass="dropdown-item">
												<la:message key="labels.administration" />
											</la:link>
										</c:if>
										<la:link href="/logout/" styleClass="dropdown-item">
											<la:message key="labels.logout" />

## Псевдонимы параметров

Представьте, что вы хотите использовать query-параметр с названием `item-query`.

Например:

```
http://127.0.0.1:8000/items/?item-query=foobaritems
```

Но `item-query` является невалидным именем переменной в Python.

Наиболее похожее валидное имя `item_query`.

Но вам всё равно необходим `item-query`...

///

Bunun anlamı şudur: "`items` değişkeni bir `list`tir ve bu listedeki öğelerin her biri bir `str`dir".

Bunu yaparak, düzenleyicinizin listedeki öğeleri işlerken bile destek sağlamasını sağlayabilirsiniz:

<img src="/img/python-types/image05.png">

Tip belirteçleri olmadan, bunu başarmak neredeyse imkansızdır.

`item` değişkeninin `items` listesindeki öğelerden biri olduğuna dikkat edin.

* `externalDocs`: 외부 문서를 설명하는 `dict`이며:
    * `description`: 외부 문서에 대한 간단한 설명을 담은 `str`입니다.
    * `url` (**필수**): 외부 문서의 URL을 담은 `str`입니다.

### 태그에 대한 메타데이터 생성

`users` 및 `items`에 대한 태그 예시와 함께 메타데이터를 생성하고 이를 `openapi_tags` 매개변수로 전달해 보겠습니다:

{* ../../docs_src/metadata/tutorial004.py hl[3:16,18] *}

설명 안에 마크다운을 사용할 수 있습니다. 예를 들어 "login"은 굵게(**login**) 표시되고, "fancy"는 기울임꼴(_fancy_)로 표시됩니다.

/// tip

                                    </tr>
                                    </thead>
                                    <tbody>
                                    <c:forEach var="data" varStatus="s" items="${dictFiles}">
                                        <tr data-href="${f:h(data.type)}/?dictId=${f:h(data.id)}">
                                            <td>${f:h(data.path)}</td>

 * features}, the features supported by the iterator; and {@code expectedElements}, the elements the
