在全局函数中完成LoggerAppender的初始化工作

initializeFactoryRegistry();

void initializeFactoryRegistry() {

        AppenderFactoryRegistry& reg = getAppenderFactoryRegistry();

        auto_ptr<AppenderFactory> ptr1(new ConsoleAppenderFactory());

        reg.put(ptr1);

        auto_ptr<AppenderFactory> ptr2(new NullAppenderFactory());

        reg.put(ptr2);

        auto_ptr<AppenderFactory> ptr3(new FileAppenderFactory());

        reg.put(ptr3);

        auto_ptr<AppenderFactory> ptr4(new RollingFileAppenderFactory());

        reg.put(ptr4);

        auto_ptr<AppenderFactory> ptr5(new DailyRollingFileAppenderFactory());

        reg.put(ptr5);

        auto_ptr<AppenderFactory> ptr6(new SocketAppenderFactory());

        reg.put(ptr6);

#if defined(_WIN32)

        auto_ptr<AppenderFactory> ptr7(new NTEventLogAppenderFactory());

        reg.put(ptr7);

#elif defined(HAVE_SYSLOG_H)

        auto_ptr<AppenderFactory> ptr8(new SysLogAppenderFactory());

        reg.put(ptr8);

#endif

        LayoutFactoryRegistry& reg2 = getLayoutFactoryRegistry();

        auto_ptr<LayoutFactory> ptr21(new SimpleLayoutFactory());

        reg2.put(ptr21);

        auto_ptr<LayoutFactory> ptr22(new TTCCLayoutFactory());

        reg2.put(ptr22);

        auto_ptr<LayoutFactory> ptr23(new PatternLayoutFactory());

        reg2.put(ptr23);

        FilterFactoryRegistry& reg3 = getFilterFactoryRegistry();

        auto_ptr<FilterFactory> ptr31(new DenyAllFilterFactory());

        reg3.put(ptr31);

        auto_ptr<FilterFactory> ptr32(new LogLevelMatchFilterFactory());

        reg3.put(ptr32);

        auto_ptr<FilterFactory> ptr33(new LogLevelRangeFilterFactory());

        reg3.put(ptr33);

        auto_ptr<FilterFactory> ptr34(new StringMatchFilterFactory());

        reg3.put(ptr34);

}

通过这种方式来实现 

              AppenderFactoryRegistry

                   LayoutFactoryRegistry

                   FilterFactoryRegistry

                   的初始化工作 – 如果要加入新的类型的数据的支持,需要将这部分的内容也要实现

         如何利用Registry中的内容来实现对象数据的创建?

注意

得到的指针内容都是Factory中定义的内容,

通过调用Factory方法来获取具体的能够使用的对象的实例
