Virtual

Virtual是定义C++中虚函数的关键字。在面向对象程序设计领域,C++、ObjectPascal等语言中有虚函数(英语:Virtualfunction)或虚方法(英语:Virtualmethod)的概念。这种函数或方法可以被子类继承和覆盖,通常使用动态调度实现。这一概念是面向对象程序设计中(运行时)多态的重要组成部分。简言之,虚函数可以给出目标函数的定义,但该目标的具体指向在编译期可能无法确定。

    radius协议源码÷The Radius Stack will connect to a Radius Server. This stack implementation is built upon the UdpStack which is available in the radius{version}/util directory. A minimal set of VSAs (Vendor Specific Attributes are supported by this stack). The Radius Stack should be used as a base class. In order to implement a larger set of VSAs, one will need to subclass from the Radius Stack and implement the functionality within the Virtual function processVsa(). The Radius Stack supports mostly accounting messages. The authentcation messages will be supported in a future release. A test program has been provided in the radius directory. This program shows how to subclass from the RadiusStack and how to use the api.

  • The Linux Enterprise Cluster explains how to take a number of inexpensive computers with limited res

    The Linux Enterprise Cluster explains how to take a number of inexpensive computers with limited resources, place them on a normal computer network, and install free software so that the computers act together like one powerful server. This makes it possible to build a very inexpensive and reliable business system for a small business or a large corporation. The book includes information on how to build a high-availability server pair using the Heartbeat package, how to use the Linux Virtual Server load balancing software, how to configure a reliable printing system in a Linux cluster environment, and how to build a job scheduling system in Linux with no single point of failure. The book also includes information on high availability techniques that can be used with or without a cluster, making it helpful for System Administrators even if they are not building a cluster. Anyone interested in deploying Linux in an environment where low cost computer reliability is important will find this book useful.

    THIS book covers the Java™ Native Interface (JNI). It will be useful to you if you are interested in any of the following: • integrating a Java application with legacy code written in languages such as C or C++ • incorporating a Java Virtual machine implementation into an existing application written in languages such as C or C++ • implementing a Java Virtual machine • understanding the technical issues in language interoperability, in particular how to handle features such as garbage collection and multithreading
