| initialization TAutoObjectFactory.Create(ComServer, TChatManager, Class_ChatManager, ciMultiInstance, tmApartment); end. 比较关键TchatRoom是下面的样子： type TChatRoom=class private FBuffer:array[1..20] of string; FBufferLength:integer; FRoomName:string; FRoomID:integer; FLocked:boolean;//同步锁，用来处理多人同时发出对话的情况 FConnectCount:integer;//当前房间的人数 FClearBufferTag:integer; //每清空一次buffer此值便跳变一次，此脉冲被客户端检测 protected procedure ClearBuffer;//清空缓冲区 function GetCanRead:boolean; public constructor Create(RoomName:string;RoomID:integer); procedure OneSpeak(content:string);//将一条聊天内容加入缓冲区 procedure LoginRoom(UserName:string);//参看实现部分注释 procedure LeaveRoom(UserName:string);//参看实现部分注释 function OneRead:Tstrings;//从缓冲区中读出记录 property Locked:boolean read FLocked; //readonly;//供IChatManager检测 property CanRead:boolean read GetCanRead;//判断缓冲区是否为空，否则是不可读的 property ClearBufferTag:integer read FClearBufferTag; end; |
