ice Slice语言 定义一个分布式文件系统

//名称:远程文件系统
//

module filesystem
{
//-------------------数据类型--------------------------------------------------------
 sequence<byte> rfsstream;//文件读写系列
 struct rfsnode
 {
     string name;//文件或者目录的名称

 };   
 sequence<rfsnode> rfsnodelist;//文件目录列表
 
//------------------异常处理----------------------------------------------------------
    exception rfserror
    {
     string reason;
    };
//------------------接口实现----------------------------------------------------------
