网络虚接口对特殊数据包的处理起着很大的作用。
Virtual Network Interface(VNI)plays an important role in processing data packets for special-purpose.
该功能建立在IDS提供的虚表接口（VTI）之上。
This functionality is built upon the virtual table interface (VTI) provided by IDS.
SessionEJBAccountManagement 担任Web应用程序或客户端的会话虚包来访问实体EJB，因此支持远程接口。
Session EJB AccountManagement acts as a session facade for Web applications or clients to access entity EJBs and thus supports the remote interface.
这一部分研究虚包模式 [DP]在接口设计方面的应用，以及如何使用它来保存更多的远程调用。
This section investigates the application of the facade pattern [ DP] to the interface design and how you can use it to save even more remote calls.
AccountTransaction充当了一个供web应用程序或客户端访问实体e JB组件的会话虚包，因此它支持远程接口。
AccountTransaction ACTS as a session facade for Web applications or clients to access entity EJB components, and thus supports the remote interface.
此外，透明方法不能重写关键虚方法，也不能实现关键接口方法。
In addition, transparent methods cannot override critical virtual methods or implement critical interface methods.
内存开销非常小：基本上每个接口需要额外4个字节（对象实例数据里虚函数表指针），加上引用计数的4个字节。
Overhead in memory is very small: You basically have a 4- byte overhead per interface (the vtable pointers in the object's instance data) plus 4 bytes for the reference counter.
这个函数允许客户端请求对象提供关于自己的其它方面的指针，这个新指针同样指向不同的虚基类（也叫做接口）。
This function allows a client to ask the object for different pointers to itself that also point to different abstract base classes (also known as interfaces).
