<span>该类提供了Attributes界面的基本实现。</span>
<p> <span>BasicAttributes是区分大小写或不区分大小写（case-ignore）。</span> <span>此属性在BasicAttributes构造函数调用时确定。</span> <span>在不区分大小写的BasicAttributes中，在搜索属性或添加属性时忽略其属性标识符的情况。</span> <span>在一个区分大小写的BasicAttributes中，情况很重要。</span> </p>
<p> <span>当BasicAttributes类需要创建一个Attribute时，它使用BasicAttribute。</span> <span>对BasicAttribute没有其他依赖。</span> </p>
<p> <span>请注意，对BasicAttributes的更新（例如添加或删除属性）不会影响目录中的相应表示。</span> <span>只能使用DirContext界面中的操作来更新目录。</span> </p>
<p> <span>BasicAttributes实例与并发多线程访问不同步。</span> <span>尝试访问和修改单个BasicAttributes实例的多个线程应锁定该对象。</span> </p>

<div class="block">
<span>创建并返回此对象的副本。</span>
<span>“复制”的精确含义可能取决于对象的类。</span>
<span>一般的意图是，对于任何对象<code>x</code> ，表达式：</span>
<blockquote>
<span><pre>
 x.clone() != x</pre></span>
</blockquote>
<span>将是真实的，而且表达：</span>
<blockquote>
<span><pre>
 x.clone().getClass() == x.getClass()</pre></span>
</blockquote>
<span>将是<code>true</code> ，但这些都不是绝对要求。</span>
<span>通常情况是：</span>
<blockquote>
<span><pre>
 x.clone().equals(x)</pre></span>
</blockquote>
<span>将是<code>true</code> ，这不是一个绝对的要求。</span>
<p> <span>按照惯例，返回的对象应该通过调用<code>super.clone</code>获得。</span> <span>如果一个类和它的所有超类（除了<code>Object</code> ）遵守这个约定，那将是<code>x.clone().getClass() == x.getClass()</code>的情况。</span> </p>
<p> <span>按照惯例，此方法返回的对象应该与此对象（正被克隆）无关。</span> <span>为了实现这种独立性，可能需要修改<code>super.clone</code>返回的对象的一个或多个字段。</span> <span>通常，这意味着复制构成被克隆的对象的内部“深层结构”的任何可变对象，并通过引用该副本替换对这些对象的引用。</span> <span>如果一个类仅包含原始字段或对不可变对象的引用，则通常情况下不需要修改<code>super.clone</code>返回的对象中的字段。</span> </p>
<p> <span><code>clone</code>的方法<code>Object</code>执行特定的克隆操作。</span> <span>首先，如果此对象的类不实现接口<code>Cloneable</code> ，则抛出<code>CloneNotSupportedException</code> 。</span> <span>请注意，所有阵列被认为是实现该接口<code>Cloneable</code>和所述的返回类型<code>clone</code>数组类型的方法<code>T[]</code>是<code>T[]</code>其中T是任何引用或原始类型。</span> <span>否则，该方法将创建该对象的类的新实例，并将其所有字段初始化为完全符合该对象的相应字段的内容，就像通过赋值一样。</span> <span>这些字段的内容本身不被克隆。</span> <span>因此，该方法执行该对象的“浅拷贝”，而不是“深度拷贝”操作。</span> </p>
<p> <span><code>Object</code>类本身不实现接口<code>Cloneable</code> ，因此在类别为<code>Object</code>的对象上调用<code>clone</code>方法将导致运行时抛出异常。</span> </p>
