"ACE程序员指南 - 大名鼎鼎的ACE框架,适用于C++网络编程,提供了一套强大的自适配通信环境,用于实现高效、灵活、可靠的并发和分布式软件。" ACE框架是面向对象设计的一个核心组件集合,专注于通信软件的开发,它提供了丰富的功能,包括但不限于并发和同步机制、进程间通信、内存管理、定时器、信号处理、文件系统操作、线程管理、事件多路分离、处理器分派、连接建立、服务初始化、软件配置与重配置、分层协议构建、流式框架以及分布式通信服务,如命名、日志、时间同步、事件路由和网络锁定等。 ACE的体系结构分为三个主要层次: 1. **操作系统(OS)适配层**:这是最底层,它是一个薄的代码层,介于本地操作系统API和ACE的其他部分之间。它的作用是隐藏平台的特定细节,使得ACE的上层代码能够保持高度的跨平台兼容性。这减少了开发者为不同操作系统编写特定代码的需求,提高了代码的可移植性。 2. **C++包装层**:这一层将操作系统适配层的功能封装成C++接口,提供了一个更高级别的抽象,便于C++程序员使用。通过这些接口,开发者可以利用C++的面向对象特性,如继承、多态和封装,来构建复杂的软件系统。 3. **框架和模式层**:这是ACE的最高层,包含了各种设计模式和框架,如事件处理框架、并发服务器框架等,它们是预先构建的解决方案,旨在简化常见通信问题的解决,提高开发效率和软件质量。 ACE的设计理念强调自适应性,这意味着它能够根据运行时的环境和需求动态调整其行为。例如,其并发和同步组件可以根据系统的负载和资源状况自动调整,以优化性能和响应时间。 使用ACE框架开发软件,开发者可以获得如下优势: - **可移植性**:由于ACE屏蔽了底层操作系统的差异,开发者可以编写一次代码,在多个平台上运行。 - **效率**:ACE提供了优化的低级通信机制,能够有效地处理并发和分布式任务。 - **可靠性**:ACE的组件经过了广泛测试,具有高可用性和容错性。 - **灵活性**:通过模式和框架,开发者可以快速构建和修改软件架构,以适应变化的需求。 "ACE程序员指南"是一份深入介绍如何使用ACE框架进行C++网络编程的宝贵资源,适合对高性能、跨平台通信软件开发感兴趣的程序员参考学习。通过阅读这份文档,开发者可以掌握如何利用ACE的强大功能,构建高效、可靠的分布式系统。

ACE程序员指南 [ Team LiB ] • Table of Contents ACE Programmer's Guide, The: Practical Design Patterns for Network and Systems Programming By Stephen D. Huston, James CE Johnson, Umar Syyid Publisher : Addison Wesley Pub Date : November 14, 2003 ISBN : 0-201-69971-0 Pages : 544 "If you're designing software and systems that must be portable, flexible, extensible, predictable, reliable, and affordable, this book and the ACE toolkit will enable you to be more effective in all of these areas. Even after spending over a decade developing ACE and using it to build networked software applications, I find that I've learned a great deal from this book, and I'm confident that you will, too." -Douglas C. Schmidt, Inventor of ACE, from the Foreword "This book is a must-have for every ACE programmer. For the beginner, it explains step-by-step how to start using ACE. For the more experienced programmer, it explains in detail the features used daily, and is a perfect reference manual. It would have saved me a lot of time if this book had been available some years ago"! -Johnny Willemsen, Senior Software Engineer, Remedy IT, The Netherlands "With a large C++ code base, we rely on ACE to enable a cross-platform client-server framework for data quality and data integration. ACE has improved our design and smoothed over OS idiosyncrasies without sacrificing performance or flexibility. The combination of online reference materials and printed "big picture" guides is indispensable for us, and The ACE Programmer's Guide earns top-shelf status in my office." -John Lilley, Chief Scientist, DataLever Corporation "In SITA air-ground division, we are one of the major suppliers of communication services to the airline industry. We started using ACE about a year ago and are now moving most of our new communication-related development to it. I can say that using this toolkit can reduce the development and testing time by at least 50% in our type of application". -Jean Millo, Senior Architect, SITA The ADAPTIVE Communication Environment (ACE) is an open-source software toolkit created to solve network programming challenges. Written in C++, with the help of 30 core developers and 1,700 contributors, this portable middleware has evolved to encapsulate and augment a wide range of native OS capabilities essential to support performance-driven software systems. The ACE Programmer's Guide is a practical, hands-on guide to ACE for C++ programmers building networked applications and next-generation middleware. The book first introduces ACE to beginners. It then explains how you can tap design patterns, frameworks, and ACE to produce effective, easily maintained software systems with less time and effort. The book features discussions of programming aids, interprocess communication (IPC) issues, process and thread management, shared memory, the ACE Service Configurator framework, timer management classes, the ACE Naming Service, and more.
