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

bool type;//1=文件 0= 目录

};

sequence<RFSNode> RFSNodeList;//文件目录列表

//------------------异常处理----------------------------------------------------------

exception RFSError

{

string reason;

};

//------------------接口实现----------------------------------------------------------

interface RFSFileSystem

{ //_________用户标识______文件名称_______要读写的块 ______读写的内容_________异常处理

void FileWrite (string UserID,string FileName,int BlockNO, RFSStream FStream) throws RFSError;
