在service中定义其它对象指针时用智能指针

头文件：

#include <ncore/NCRefBase.h>

用法：

class ****

{  

private:

        ncsp<NCSSPluginManager>::sp m_pluginMgr;
        ncsp<NCSSFileListProvider>::sp m_fileListProvider;
        ncsp<NCSSEventHandler>::sp m_eventHandler;
        ncsp<NCSSScanSetting>::sp m_scanSetting;
        ncsp<NCSSThreadFactory>::sp m_threadFactory;

}
