<span>此接口表示创建对象工厂的构建器。</span>
<p> <span>JNDI框架允许通过<em>对象工厂动态</em>加载<em>对象实现</em> 。</span> <span>例如，当查找名称空间中绑定的打印机时，如果打印服务将打印机名称绑定到引用，则打印机参考可用于创建打印机对象，以便查找的调用者可以在打印机对象之后直接操作查找。</span> <span>ObjectFactory负责创建特定类型的对象。</span> <span>JNDI使用默认策略来使用和加载对象工厂。</span> <span>您可以使用<tt>ObjectFactoryBuilder</tt>调用<tt>NamingManager.setObjectFactoryBuilder()</tt>来覆盖此默认策略，该对象包含创建/加载对象工厂的程序定义方式。</span> <span>任何<tt>ObjectFactoryBuilder</tt>实现都必须实现这个用于创建对象工厂的接口。</span> </p>
