<span>提供OMG CORBA API与Java <sup><font size="-2">TM</font></sup>编程语言的映射，包括ORB类，该类<tt>实现</tt>为程序员可以将其用作全功能的对象请求代理（ORB）。</span>
|
||
<p> <span>有关官方CORBA规范的受支持部分的精确列表，Java TM平台，标准版6符合，请参阅<a href="doc-files/compliance.html"><em>Official Specifications for CORBA support in Java[TM] SE 6</em></a> 。</span> </p>
|
||
<h1> <span>一般信息</span> </h1>
|
||
<span>本节中的信息是与编辑界面定义语言（IDL）文件并使用ORB编写客户端和服务器的人相关的信息。</span>
|
||
<p> <span>本节中描述的类和接口可以分为四个组： <tt>ORB classes</tt> ，异常， <tt>Helper</tt>类和<tt>Holder</tt>类。</span> </p>
|
||
<h2> <span><tt>ORB</tt>课</span> </h2>
|
||
<p> <span>ORB在客户端和方法在服务器上的实现之间处理（或经纪人）方法调用。</span> <span>因为客户端和服务器可能在网络上的任何地方，并且由于调用和实现可能用不同的编程语言编写，所以ORB在后台进行大量的工作来完成此通信。</span> </p>
|
||
<p> <span>ORB的大部分功能对于用户来说都是完全透明的，并且<tt>CORBA</tt>包的主要部分由ORB幕后使用的类组成。</span> <span>结果是大多数程序员只能直接使用这个包的一小部分。</span> <span>实际上，大多数程序员只会使用<tt>ORB</tt>类中的几种方法，一些例外情况，偶尔还会有一个持有者类。</span> </p>
|
||
<h3> <span><tt>ORB</tt>方法</span> </h3>
|
||
<p> <span>在应用程序进入CORBA环境之前，必须首先：</span> </p>
|
||
<p></p>
|
||
<ul>
|
||
<li> <span>被初始化为ORB和可能的对象适配器（POA）环境。</span> </li>
|
||
<li> <span>获取对ORB对象的引用（用于将来的ORB操作）以及其他对象（包括根POA或一些对象适配器对象）。</span> </li>
|
||
</ul>
|
||
<p> <span>提供以下操作来初始化应用程序并获取适当的对象引用：</span> </p>
|
||
<p></p>
|
||
<ul>
|
||
<li> <span>提供对ORB的访问的操作，这将在本节中讨论。</span> </li>
|
||
<li> <span>提供对对象适配器，接口存储库，命名服务和其他对象服务的访问的操作。</span> <span>这些操作在<em>Other Classes</em>中<a href="#adv">描述</a> 。</span> </li>
|
||
</ul>
|
||
<p> <span>当应用程序需要CORBA环境时，它需要一种获取ORB对象引用和可能的OA对象引用（例如根POA）的机制。</span> <span>这有两个目的。</span> <span>首先，它将应用程序初始化到ORB和OA环境中。</span> <span>其次，它将ORB对象引用和OA对象引用返回到应用程序，以供将来的ORB和OA操作使用。</span> </p>
|
||
<p> <span>为了获得ORB对象引用，应用程序调用<tt>ORB.init</tt>操作。</span> <span>呼叫的参数可以包括需要对象引用的ORB的标识符，以及用于允许环境特定数据被传递到呼叫中的arg_list。</span> </p>
|
||
<p> <span>这些是提供对ORB访问的<tt>ORB</tt>方法：</span> </p>
|
||
<ul>
|
||
<li> <span><tt>
|
||
<bold>
|
||
init
|
||
</bold>()</tt></span> </li>
|
||
<li> <span><tt>
|
||
<bold>
|
||
init
|
||
</bold>(String [] args, Properties props)</tt></span> </li>
|
||
<li> <span><tt>
|
||
<bold>
|
||
init
|
||
</bold>(Applet app, Properties props)</tt></span> </li>
|
||
</ul>
|
||
<p> <span>使用没有参数的<tt>init()</tt>方法启动一个单例ORB，它只能通过<tt>idlj</tt>在Helper类中<tt>生成的</tt>代码中给出类型代码创建<tt>any</tt>所需的类型代码。</span> </p>
|
||
<p> <span>应用程序需要一种便携式手段来获取其初始对象引用。</span> <span>根POA，POA Current，Interface Repository和各种对象服务实例需要引用。</span> <span>应用程序所需的功能类似于命名服务提供的功能。</span> <span>但是，OMG不希望将命名服务提供给所有应用程序，以便可以对其进行可移植的初始化。</span> <span>因此，本节中显示的操作提供了简化的本地版本的命名服务，应用程序可以使用它来获取对其操作至关重要的小型定义的对象引用集。</span> <span>因为只有一个很好的定义对象集合才能使用这种机制，所以命名上下文可以被平坦化成单级名称空间。</span> <span>这种简化导致仅定义了两个操作来实现所需的功能。</span> </p>
|
||
<p> <span>初始引用通过ORB对象接口中提供的两个操作获得，提供列出和解析初始对象引用的功能。</span> <span>这些是：</span> </p>
|
||
<ul>
|
||
<li> <span><tt>
|
||
<bold>
|
||
resolve_initial_references
|
||
</bold>(String name)</tt></span> </li>
|
||
<li> <span><tt>
|
||
<bold>
|
||
list_initial_services
|
||
</bold>()</tt></span> </li>
|
||
<li> <span><tt>
|
||
<bold>
|
||
register_initial_reference
|
||
</bold>(String id, org.omg.CORBA.Object obj)</tt></span> </li>
|
||
</ul>
|
||
<p> <span>使用其中一些方法的示例是<a href="../../../../technotes/guides/idl/GShome.html"><em>Getting Started with Java IDL</em></a> 。</span> </p>
|
||
<h2> <span>例外</span> </h2>
|
||
<span>Java IDL中的异常与使用Java编程语言编写的任何代码类似。</span>
|
||
<span>如果一个方法被定义为抛出异常，然后使用该方法的任何代码必须有一个<tt><tt>catch分之try</tt></tt>块和处理该异常，当它被抛出。</span>
|
||
<p> <span>关于<em>Java IDL exceptions</em>的<a href="../../../../technotes/guides/idl/jidlExceptions.html">文档</a>有更多的信息，并解释了系统异常和用户定义的异常之间的区别。</span> </p>
|
||
<p> <span>以下是包装<tt>org.omg.CORBA</tt>中定义的系统异常（未经检查通过<tt><a href="SystemException.html"> org.omg.CORBA.SystemException</a></tt>从<tt>java.lang.RuntimeException继承的异常</tt> ）的<tt>列表</tt> ：</span> </p>

<p> <span>以下是包<tt>org.omg.CORBA中</tt>定义的用户定义异常的列表。</span> </p>
|
||
<pre> <span><code> Bounds UnknownUserException WrongTransaction PolicyError </code></span> </pre>
|
||
<h2> <span>子包</span> </h2>
|
||
<span><tt>CORBA</tt>包中有一些包， <tt>其中</tt>包是“包”，作为其名称的一部分。</span>
|
||
<span>这些软件包通常非常小，因为它们所做的一切都是提供<tt>CORBA</tt>软件包中的<tt>接口</tt>和类使用的异常或类。</span>
|
||
<p> <span>例如，包<tt><a href="TypeCodePackage/package-summary.html"> org.omg.CORBA.TypeCodePackage</a></tt>包含两个例外通过方法在类<tt>TypeCode</tt>抛出。</span> <span>这些例外是：</span> </p>
|
||
<ul>
|
||
<li> <span><tt>BadKind</tt></span> </li>
|
||
<li> <span><tt>Bounds</tt></span> </li>
|
||
</ul>
|
||
<span>包<tt><a href="ORBPackage/package-summary.html"> org.omg.CORBA.ORBPackage</a></tt>包含两个例外：</span>

<ul>
|

<li> <span><tt>InvalidName</tt></span> </li>
|
||
<li> <span><tt>InconsistentTypeCode</tt></span> </li>
|

</ul>
|
||
<p> <span>另一个包是<tt>CORBA</tt>的<tt>子</tt>包是<tt><a href="portable/package-summary.html">portable</a></tt>包。</span> <span>它提供了一组ORB API，使得一个供应商的IDL编译器生成的代码可以在另一个供应商的ORB上运行。</span> </p>
|
||
<h2> <span>持有人类</span> </h2>
|
||
<p> <span>支持out和inout参数传递模式需要使用额外的<em><a href="doc-files/generatedfiles.html#holder">holder classes</a></em> 。</span> <span>由于Java编程语言不支持out或inout参数，因此需要持有者类作为传递可修改参数的方法。</span> <span>为了支持便携式存根和骨架，持有者类也实现了<tt><a href="portable/Streamable.html">org.omg.CORBA.portable.Streamable</a></tt>接口。</span> </p>
|
||
<p> <span>持有人类通过将“持有人”附加到类型的名称来命名。</span> <span>该类型的名称指的是其Java编程语言中的名称。</span> <span>例如，对于Java编程语言命名为<tt>Account</tt>的接口holder类将被命名为<tt>AccountHolder。</tt></span> </p>
|
||
<p> <span><tt>org.omg.CORBA</tt>包中的所有基本IDL数据类型都支持持有者类。</span> <span>因此，举例来说，目前已经定义的类<tt><tt><tt>LongHolder，ShortHolder，FloatHolder，</tt></tt></tt>等等。</span> <span>除了typedefs定义的所有用户定义的IDL类型之外， <tt>还会生成类</tt> 。</span> <span>（请注意，在本文中，用户定义包括在OMG规范中定义的类型，例如Interface Repository和其他OMG服务的类型。）</span> </p>
|
||
<p> <span>每个持有人类有：</span> </p>
|
||
<p></p>
|
||
<ul>
|
||
<li> <span>一个实例的构造函数</span> </li>
|
||
<li> <span>一个默认构造函数</span> </li>
|
||
<li> <span>一个公共实例成员， <tt>value</tt>是类型值。</span> </li>
|
||
<li> <span>一种读取输入流并将内容分配给类型的<tt>value</tt>字段的方法</span> </li>
|
||
<li> <span>一种将<tt>value</tt>字段的值写入输出流的方法</span> </li>
|
||
<li> <span>获取类型代码的方法</span> </li>
|
||
</ul>
|
||
<p> <span>默认构造函数将值字段设置为由Java语言定义的类型的默认值：</span> </p>
|
||
<p></p>
|
||
<ul>
|
||
<li> <span><tt>false</tt>用于布尔值</span> </li>
|
||
<li> <span><tt>0</tt>用于数字和字符类型</span> </li>
|
||
<li> <span><tt>null</tt>用于字符串和对象引用</span> </li>
|
||
</ul>
|
||
<p> <span>例如，如果将OMG IDL中定义的接口<code>Account</code>映射到Java编程语言，则将生成以下持有者类：</span> </p>
|
||
<pre> <span>public final class AccountHolder implements
|
||
org.omg.CORBA.portable.Streamable

|

public AccountHolder (Account initialValue)
|
||
{

value = initialValue;
|

}
|

<h2> <span>助手班</span> </h2>
|
||
<p> <span>助手文件提供了几种处理类型所需的静态方法。</span> <span>这些包括：</span> </p>
|
||
<p></p>
|
||
<ul>
|
||
<li> <span><tt>Any</tt>插入和提取类型的操作</span> </li>
|
||
<li> <span>获取存储库ID</span> </li>
|
||
<li> <span>得到类型代码</span> </li>
|
||
<li> <span>从流读取和写入类型</span> </li>
|
||
<li> <span>实现<code>ValueHelper</code>接口（如果是用户定义的值类型）</span> </li>
|
||
</ul>
|
||
<p> <span>映射IDL接口或抽象接口的帮助类也包括窄操作。</span> <span>静态窄方法允许将<tt>org.omg.CORBA.Object</tt>缩小为更具体类型的对象引用。</span> <span>如果由于对象引用不支持所请求的类型，则narrow会导致IDL异常<tt>CORBA.BAD_PARAM</tt>抛出。</span> <span>引起不同的系统异常以指示其他种类的错误。</span> <span>尝试缩小<tt>null</tt>将始终成功，返回值为<tt>null</tt> 。</span> <span>通常，应用程序员使用的唯一辅助方法是<code>narrow</code>方法。</span> <span>其他方法通常在幕后使用，对程序员是透明的。</span> </p>
|
||
<p> <span>助手班分为两大类： <a href="#value">helpers for value types</a>和<a href="#basic">helpers for non value types</a> 。</span> <span>因为一个类别中的所有帮助类都提供相同的方法，所以在这里给出了每类帮助类的一个通用说明。</span> </p>
|
||
<p> <span>当OMG IDL被映射到Java编程语言时，为每个用户定义的类型生成一个“帮助”类。</span> <span>该生成的类将具有附加后缀<code>Helper</code>的用户定义类型的名称。</span> <span>例如，如果界面<code>Account</code>在OMG IDL中定义， <code>idlj</code>编译器将自动生成一个名为<code>AccountHelper</code>的类。</span> <span><code>AccountHelper</code>类将包含操作类型实例所需的静态方法，在这种情况下为<code>Account</code>对象。</span> <span><a name="narrow"></a></span> </p>
|
||
<h3> <span><code>narrow</code>方法</span> </h3>
|
||
<span>当一个对象是方法的返回值时，它将以通用对象的形式返回，即<code>org.omg.CORBA.Object</code>对象或<code>java.lang.Object</code>对象。</span>
|
||
<span>必须将该对象转换为更具体的类型才能操作。</span>
|
||
<span>例如， <code>Account</code>对象将作为通用对象返回，并且必须缩小为<code>Account</code>对象，以便可以调用<code>Account</code>方法。</span>
|
||
<p> <span><code>narrow</code>方法有两种形式，一种为<code>org.omg.CORBA.Object</code>对象，一种为<code>java.lang.Object</code>对象。</span> <span>界面是抽象的还是<code>narrow</code>它的助手类将提供哪些<code>narrow</code>方法。</span> <span>不是抽象的接口的帮助类将具有<code>narrow</code>方法，该方法采用CORBA对象，而抽象接口的<code>narrow</code>方法将采用Java编程语言中的对象。</span> <span>具有至少一个抽象基础接口的非抽象接口的帮助类将提供<code>narrow</code>方法的两个版本。</span> </p>
|
||
<p> <span><a href="../../../../technotes/guides/idl/jidlExample.html"><em>Hello World</em></a>教程使用<tt>narrow</tt>方法，如下所示：</span> </p>
|
||
<p></p>
|
||
<pre> <span>// create and initialize the ORB
|
||
ORB orb = ORB.init(args, null);
|

||
// get the root naming context
|
||
org.omg.CORBA.Object objRef =
|

|
||
// Use NamingContextExt instead of NamingContext. This is
|
||
// part of latest Inter-Operable naming Service.
|
||
NamingContextExt ncRef = NamingContextExtHelper.narrow(objRef);
|
||
|
||
// resolve the Object Reference in Naming
|
||

<h3> <span>基本助手类的示例</span> </h3>
|
||
<span>为了解释这个目的，一个基本的帮助类是每个帮助类提供的方法，另外还有一个<code>narrow</code>方法，如果在OMG IDL中定义的类型映射到Java编程语言的接口。</span>
|
||
<span>不是类型的类型将为它们生成一个基本的帮助类。</span>
|
||
<p> <span>例如，假设接口<code>Account</code>不是值类型IDL类型，也不是抽象接口，没有抽象的基本接口，它的<code>AccountHelper</code>类将如下所示：</span> </p>

|
||
<h1> <span>其他类</span> </h1>
|
||
<span>在幕后使用的<tt>CORBA</tt>包中的其他类和接口可以分为四组。</span>
|
||
<span>其中三个组用于具有某种能力的请求，第四组关于Interface Repository本身就是一个类别。</span>
|
||
<h2> <span>ORB创建的类</span> </h2>
|
||
<span>第一组包含由ORB创建并包含在请求操作中使用的信息的类。</span>
|
||
<ul>
|
||
<li> <span><tt>TCKind</tt> - 表示<tt>TypeCode</tt>对象的种类（数据类型）</span> </li>
|
||
<li> <span><tt>TypeCode</tt> - 表示数据类型和可能的其他信息</span> </li>
|
||
<li> <span><tt>Any</tt> - 包含一个值及其类型代码</span> </li>
|
||
<li> <span><tt>NamedValue</tt> - 包含一个名称，一个<tt>Any</tt>对象和一个参数模式标志。</span> <span><tt>NamedValue</tt>对象包含有关方法参数，方法返回值或上下文的信息。</span> </li>
|
||
<li> <span><tt>ContextList</tt> - 描述需要解析并通过调用发送的上下文的字符串列表</span> </li>
|
||
<li> <span><tt>ExceptionList</tt> - 可能由方法抛出异常的<tt>TypeCode</tt> s的列表</span> </li>
|
||
<li> <span><tt>Environment</tt> - 在方法调用期间抛出异常的容器</span> </li>
|
||
<li> <span><tt>Context</tt> - 用于将辅助信息从客户端传递到服务器的<tt>NamedValue</tt>对象的列表</span> </li>
|
||
<li> <span><tt>NVList</tt> - 用于传递参数或获取结果的<tt>NamedValue</tt>对象的列表</span> </li>
|
||
</ul>
|
||
<h2> <span>处理请求的类</span> </h2>
|
||
<span>第二类课程涉及要求：</span>
|
||
<ul>
|
||
<li> <span><tt>Object</tt> - 所有CORBA对象引用的基类</span> </li>
|
||
<li> <span><tt>Request</tt> - DII中的主类，其中包含用于向请求添加参数的方法，用于访问有关正在调用的方法的信息（方法名称，其参数，它们抛出的异常等），并进行调用请求</span> </li>
|
||
<li> <span><tt>DynamicImplementation</tt> - 使用DSI的服务器实现的基类。</span> <span>它具有方法<tt>invoke</tt> ，由该类的实现用于确定<tt>ServerRequest</tt>对象的状态并设置其结果或异常</span> </li>
|
||
<li> <span><tt>ServerRequest</tt> - 捕获动态骨架接口请求的显式状态</span> </li>
|
||
</ul>
|
||
<h2> <span>作为常量的接口</span> </h2>
|
||
<span>第三组包含用作常量的接口。</span>
|
||
<span>IDL到Java映射要求IDL枚举映射到Java类，枚举值表示为该类中的public static final字段（例如DefinitionKind）。</span>
|
||
<span>另一方面，IDL接口外部定义的IDL常量映射到每个常量的Java接口。</span>
|
||
<p> <span>这就是为什么<tt>org.omg.CORBA</tt>包中的几个接口由一个字段<tt>value组成</tt> ，这是一个<tt>short</tt> 。</span> <span>此字段是用于诸如错误代码或值修饰符之类的常量。</span> <span>例如，接口<tt>BAD_POLICY</tt>的<tt>value</tt>字段是被抛出的为异常<tt>PolicyError</tt>的可能原因之一。</span> <span>要指定此错误代码，您将使用<tt>BAD_POLICY.value</tt> 。</span> </p>
|
||
<p> <span>例外<tt>PolicyError</tt>使用以下<tt>接口的value</tt>字段作为其可能的错误代码。</span> </p>
|
||
<ul>
|
||
<li> <span><tt>BAD_POLICY</tt></span> </li>
|
||
<li> <span><tt>BAD_POLICY_TYPE</tt></span> </li>
|
||
<li> <span><tt>BAD_POLICY_VALUE</tt></span> </li>
|
||
<li> <span><tt>UNSUPPORTED_POLICY</tt></span> </li>
|
||
<li> <span><tt>UNSUPPORTED_POLICY_VALUE</tt></span> </li>
|
||
</ul>
|
||
<span>方法<tt>TypeCode.type_modifier</tt>返回以下<tt>接口</tt>之一的value字段。</span>
|
||
<span>这些<tt>接口</tt>的名称中的VM代表“值修饰符”。</span>
|
||
<ul>
|
||
<li> <span><tt>VM_NONE</tt></span> </li>
|
||
<li> <span><tt>VM_ABSTRACT</tt></span> </li>
|
||
<li> <span><tt>VM_CUSTOM</tt></span> </li>
|
||
<li> <span><tt>VM_TRUNCATABLE</tt></span> </li>
|
||
</ul>
|
||
<span>以下常数由<code>ValueMember</code>对象的访问方法返回，以表示<code>ValueMember</code>对象的<code>ValueMember</code> 。</span>
|
||
<ul>
|
||
<li> <span><tt>PRIVATE_MEMBER</tt></span> </li>
|
||
<li> <span><tt>PUBLIC_MEMBER</tt></span> </li>
|
||
</ul>
|
||
<span>在<tt>NamedValue</tt>对象或方法参数中使用的这些标志在<tt>以下接口</tt>中定义：</span>
|
||
<ul>
|
||
<li> <span><tt>ARG_IN</tt></span> </li>
|
||
<li> <span><tt>ARG_INOUT</tt></span> </li>
|
||
<li> <span><tt>ARG_OUT</tt></span> </li>
|
||
<li> <span><tt>CTX_RESTRICT_SCOPE</tt></span> </li>
|
||
</ul>
|
||
<h2> <span>接口存储库接口和类</span> </h2>
|
||
<span>第四组包含Interface Repository接口和类，它们由OMG IDL接口ir.idl的<tt>idlj</tt>编译器<tt>生成</tt> 。</span>
|
||
<span>Interface Repository的目的是识别存储在其中的接口，以便它们可被ORB访问。</span>
|
||
<span>Interface Repository API完全描述每个模块，类型，接口，属性，操作，参数，异常，常量等。</span>
|
||
<p> <span>ORB不要求有一个接口存储库，Java IDL不包含一个。</span> <span>即使此版本不包括接口存储库的实现，为了创建类型代码，已经包括以下IR类和接口（请参阅org.omg.CORBA.ORB接口中的create_value_tc，create_struct_tc，create_union_tc和create_exception_tc方法）：</span> <br/> <span>＆nbs</span> </p>
|
||
<ul>
|
||
<li> <span>IRObject</span> </li>
|
||
<li> <span>IDLType</span> </li>
|
||
<li> <span>定义属性</span> </li>
|

<li> <span>StructMember</span> </li>
