## 4. Data Structures

### 4.1 Witness Registration
```java
package jcifs.internal.witness;

import java.net.InetAddress;

중요한 부분은 **`Annotated` 안에서 함수와 함께 `AfterValidator`를 사용한다는 것**뿐입니다. 이 부분은 건너뛰셔도 됩니다. 🤸

하지만 이 특정 코드 예제가 궁금하고 계속 보고 싶다면, 추가 세부사항은 다음과 같습니다.

#### `value.startswith()`를 사용한 문자열 { #string-with-value-startswith }

알고 계셨나요? `value.startswith()`를 사용하는 문자열은 튜플을 받을 수 있으며, 튜플에 있는 각 값을 확인합니다:

{* ../../docs_src/query_params_str_validations/tutorial015_an_py310.py ln[16:19] hl[17] *}

#### 임의의 항목 { #a-random-item }

  final void setMap(Map<K, Collection<V>> map) {
    this.map = map;
    totalSize = 0;
    for (Collection<V> values : map.values()) {
      checkArgument(!values.isEmpty());
      totalSize += values.size();
    }
  }

  /**
   * Creates an unmodifiable, empty collection of values.
   *
   * <p>This is used in {@link #removeAll} on an empty key.
   */
  Collection<V> createUnmodifiableEmptyCollection() {

 * key. A {@link HashMap} associates each key with an {@link ArrayList} of values.
 *
 * <p>When iterating through the collections supplied by this class, the ordering of values for a
 * given key agrees with the order in which the values were added.
 *
 * <p>This multimap allows duplicate key-value pairs. After adding a new key-value pair equal to an

 *       com.google.common.primitives.Ints#stringConverter Ints.stringConverter} or the {@linkplain
 *       #reverse reverse} views of these.
 *   <li>Convert between specific preset values using {@link
 *       com.google.common.collect.Maps#asConverter Maps.asConverter}. For example, use this to
 *       create a "fake" converter for a unit test. It is unnecessary (and confusing) to <i>mock</i>

### 理解这段代码 { #understand-that-code }

关键点仅仅是：在 `Annotated` 中使用带函数的 **`AfterValidator`**。不感兴趣可以跳过这一节。🤸

但如果你对这个具体示例好奇，并且还愿意继续看，这里有一些额外细节。

#### 字符串与 `value.startswith()` { #string-with-value-startswith }

注意到了吗？字符串的 `value.startswith()` 可以接收一个元组，它会检查元组中的每个值：

{* ../../docs_src/query_params_str_validations/tutorial015_an_py310.py ln[16:19] hl[17] *}

#### 一个随机条目 { #a-random-item }

                if (selected.hour() >= 12) {
                    html += '<option value="AM"' + am_html + '>AM</option><option value="PM" selected="selected"' + pm_html + '>PM</option>';
                } else {
                    html += '<option value="AM" selected="selected"' + am_html + '>AM</option><option value="PM"' + pm_html + '>PM</option>';
                }

                html += '</select>';
