步骤 208、 根据该操作队列生成与该操作队列相应的消息头信息; 步骤 209、 将该操作队列与该消息头信息发送出去。
在上述步骤 201 中, 其中, 本发明实施例中的用户的身份标识具体可以 为用户通过 Web浏览器的登录界面得到的用户的身份信息, 待协同项目信息 具体可以为: 用于确保当前项目唯一性的当前项目的标识( ID )、 当前项目的 参与用户、 项目允许操作的令牌数、 项目允许的操作级别以及对应的不同级 别的令牌等, 其中, 当前项目的参与用户均为本发明实施例中令牌的候选人 贝;
上述步骤 202中, 在获取到多个用户的身份标识以及该多个用户之间的 待协同项目信息后, 可以通过进入令牌机制模块对用户的身份标识和待协同 项目信息进行处理, 具体地, 若用户作为协同者需要申请设定权限的令牌, 协同建模处理系统需要根据该用户的身份标识和待协同项目信息查找当前种 类的令牌数, 以确定当前种类的令牌数是否充足; 上述步骤 203 中, 若当前种类的令牌足够, 则依照先进先出调度(First Input First Output, 简称: FIFO )将令牌分配给申请者; 若当前种类的令牌不 够, 则优先分配给先申请的项目协同者, 其它申请者进入等待队列, 直到令 牌被释放进行重新分配。
上述步骤 204中, 命令匹配模块保存有与该待协同项目相对应的命令, 在对用户的身份标识进行权限判定时, 拥有设定权限的令牌的用户拥有对该 设定权限相对应的项目模型的操作权, 该操作权例如可以为: 添加、 删除、 修改、 缩放等。
此外, 还可以根据多个用户的身份标识所对应的令牌持有情况将多个用 户身份标识进行权限粗分组; 将粗分组后的用户的身份标识根据不同权限进 行细分组; 最后进入协同角色划分模块, 根据多个用户的令牌持有情况将用 户划分为操作许可组和操作禁止组, 操作许可组中再根据不同权限细划分为 相应操作的操作许可组, 只有相应操作许可组里的成员才对协同项目模型具 有相应的操作权。
上述步骤 205中, 在获取到对该设定权限相对应的项目模型的操作权之 后, 即可在协同模式下对该设定权限相对应的项目模型进行操作, 从而激活 与该项目模型相对应的命令匹配模块;
上述步骤 206和步骤 207中, 调用与该项目模型相应的命令, 并进行数 据分析与处理; 其中, 对数据分析与处理由待协同项目信息的格式确定, 若 该待协同项目信息的格式为 (可扩展标记语言, 简称: XML ), 则可以采取 XML特有的文档对象模型 (Document Object Model, 简称: DOM )解析方 法来提取关键数据, 再将该关键数据进行组织进一步形成本发明实施例所述 的操作队列; 若该待协同项目信息的格式为纯文本格式, 则可以采取利用特 定 "正则表达式" 来提取关键信息, 再自己组织数据称操作队列; 若为该待 协同项目信息的格式为二进制字节流, 则可以需要先将该二进制字节流反序 列化成 XML等格式, 再进行处理, 当然, 上述仅为本发明实施例的示例性 说明, 并不能形成对本发明实施例的限制, 只要通过该项目模型相应的命令, 目相对应的的命令进行操作打包, 打包成一个操作队列, 操作队列对应操作 格式具体如表 1所示。
表 1
Figure imgf000008_0001
如表 1所示, 操作是指所要进行的对图元的操作, 具体可以分为: 对图 元进行添加、 对图元进行删除、 对图元属性进行更新、 对所操作图元进行标 注、 对所操作图元前后进行比较、 将画布对焦到所操作图元所在视图中; 优 先级是所选用操作所属的优先级, 具体可以分为 1、 2、 3共 3个等级, 并且 数字越小优先级越高, 优先级的设定例如具体可以为: 优先级 1对应于对所 操作图元前后进行比较, 优先级 2对应于对图元进行添加、对图元进行删除、 对图元属性进行更新, 优先级 3对应于对所操作图元进行标注、 将画布对焦 到所操作图元所在视图中; 图元 ID是指所要操作的图元身份标识(ID ); 属 性名是指所要进行操作的属性名称, 具体可以为: 图元所属类型 (例如: 连 线、 值对象等等); 属性值是指所要进行操作的属性值。
上述步骤 208中, 根据该操作队列生成与该操作队列相对应的消息头信 息, 生成相应的消息头信息如表 2所示。
表 2
Figure imgf000008_0002
如表 2所示, 该消息头信息具体包括: 发送者 ID、 消息传输的通道、 消 息所属主题(即通道和主题决定了消息的传输路径)、 消息调用类型 (例如: WebService, RMI、 HTTP 等), 消息所用传输协议(例如: 超文本传输协议 ( HTTP ), Web服务通知( WS-Notification )协议), 具体地, 发送者 ID是 记录唯一标识消息发送者的信息,消息传输通道是标识消息传输所选择的通道
ID, 消息所属主题是标识消息所属通道下的主题, 消息调用类型是标识消息如 何被调用, 例如: 远程过程调用协议 ( Remote Procedure Call Protocol , 简称: RPC或 Web服务(Service )等, 所用协议是标识消息传输所采用的协议。
此外, 还可以对消息头信息所包含的消息附加信息进行处理, 该消息附 加信息具体可以为一些辅助信息, 例如: 完整性验证码等; 进一步地, 还可 以将消息头、 消息体(即操作)、 消息附加信息打包成为固定格式的消息, 该 固定格式如表 3所示。
表 3
Figure imgf000009_0001
附件信息 如表 3所示, 消息头是消息的主要信息, 用来辨别消息的类别; 消息体 是消息信息携带者, 用来提供消息的基本数据, 具体可以为指令队列, 例如: 包含所操作的一个或一组图元的指令队列; 附加信息是消息的一些辅助信 息, 例如: 完整性验证信息等。
上述步骤 209中, 通过消息发送模块进行相应发送, 具体地, 可以通过 消息广播的方式发送至订阅该消息的用户中。

为了更清楚的理解本发明实施例的技术方案, 下面通过图 5对本发明实 施例进行具体描述; 图 5为本发明实施例所适用的协同建模处理系统的结构 示意图。
如图 5所示, 本发明实施例所适用的协同建模处理系统 50包括: 消息预 处理模块 51、 消息操作模块 52、 访问控制模块 53、 模式转换模块 54、 数据 处理模块 55、 服务处理模块 56、 发送模块 57以及协同组件集 58。 此外, 图 3和图 4所示实施例中的各个功能模块或者单元只要与图 5所示实施例功能 模块具有相同的功能, 即可视为相同的功能模块。
其中, 消息预处理模块 51通过 Web浏览器获取来自多个用户的协同消 息, 对该协同消息进行拆包, 提取出该协同消息中的主要信息, 该协同消息 中的主要信息具体可以包括: 消息头、 消息体、 附加信息以及每个部分所包 含的所有的详细信息, 将该协同消息解析为带有信息的对象模型, 该对象模 型具体指预设的包含有消息头、 消息体、 附加信息的消息格式; 为了确保该 协同消息在传递过程中完整无丟失,消息预处理模块 51还对该协同消息进行 验证, 若验证不通过, 则确定该协同消息为无效信息, 根据消息处理策略对 该协同消息进行相应处理, 其中, 消息头、 消息体、 附加信息的详细描述请 参见对表 3的描述, 在此不再赘述; 此外, 为了避免同时接收两条协同消息 而导致资源争用冲突, 还可以对两条以上的协同消息进行资源处理, 以确保 每一时刻只处理一条协同消息; 进一步地, 本实施例中的消息预处理模块 51 还可以包括图 3所示实施例中的第一获耳 莫块 31或者图 4所示实施例中的第 一获取模块 41。
在消息预处理模块 51确认该协同消息为有效消息的情况下,消息操作模 块 52分析该协同消息所请求触发的命令以及该协同消息所携带的参数。
在消息操作模块 52获取到该协同消息所请求触发的命令后,访问控制模 块 53 负责多个用户在协同过程中的资源访问控制; 具体地, 访问控制模块 53查找当前的令牌数, 如果当前的令牌足够分配, 则依照 FIFO的顺序将令 牌分配给多个用户; 如果当前的令牌不够分配, 则优先分配给多个用户中的 先发送协同消息的项目协同者; 此时, 拥有令牌的用户即可拥有对该协同消 息相对应的项目模型的操作权, 该操作权具体可以包括但不限于: 添加、 删 除、 修改、 缩放等, 而无令牌的用户只有访问权限; 进一步地, 访问控制模 块 53还可以根据多个用户的令牌持有情况将用户进行粗分类, 例如: 将多个 用户划分为操作许可组和操作禁止组, 只有操作许可组里的用户才可以对协 同项目模型具有操作权; 进一步地, 本实施例中的访问控制模块 53还可以包 括图 3所示实施例中的第二获取模块 32或者图 4所示实施例中的第二获耳 莫 块 42。
在访问控制模块 53确定多个用户的访问权限后, 模式转换模块 54根据 参与用户的选择, 可以产生以下协同模式: 可操作普通协同模式、 可操作协 同标注模式、 可操作协同比较模式、 可操作协同比较 -标注模式、 观察者普通 协同模式、 观察者协同标注模式、 观察者协同比较模式、 观察者协同比较-标 注模式; 其中, 协同标注模式可以使得在大型协同项目中协同操作被红色标 注出方便协同参与者识别协同操作, 提高项目协同的效率; 协同比较模式可 以使得在大型协同项目中上一次图元状态实时以虚影形式呈现, 方便协同参 与者将本次协同操作与上次协同操作进行比较, 提高项目协同的效率; 无标 注和虚影即为普通模式; 访问控制模块 53首先接收到用户的协同模式请求, 根据该协同模式请求调用对应的协同模式。
数据处理模块 55用于对协同数据的加工与处理; 具体地, 在消息操作模 块 52 分析得到该协同消息所请求触发的命令以及该协同消息所携带的参数 后,数据处理模块 55根据该协同消息所请求触发的命令以及该协同消息所携 带的参数通过匹配命令将该协同消息所请求触发的命令接入到对应的命令实 体中, 并进行相应的数据分析与处理, 将处理结果进行打包, 并发送给服务 处理模块 56; 进一步地, 本实施例中的访问控制模块 53还可以包括图 3所 示实施例中的操作处理模块 33或者图 4所示实施例中的操作处理模块 43。
服务处理模块 56作为协同消息的出口, 在接收到数据处理模块 55所进 行操作打包后的协同消息, 对该协同消息进行路由选择, 再将该打包后的协 同消息通过发送模块 57进行发送, 至此, 完成本发明实施例中的协同建模处 理过程。
此外,本发明实施例中的协同组件集 58作为伴随整个协同建模处理过程 的模块, 该协同组建集 58具体可以为即时消息组件、 视频组件、 音频组件、 E-mail等组件, 以便于多个用户在进行协同时的交流。
进一步地, 本发明实施例中的协同建模处理系统具体可以为服务器, 通 过 Web浏览器获取多个用户的身份标识以及待协同项目信息, 进一步由浏览 器 /服务器(Browser/Server, 简称: B/S ) 系统形成协同体系结构, 避免了多 个用户中不需要协同的用户也对该待协同项目信息所对应的项目模型进行非 法操作, 基于令牌的访问控制机制确保了多用户协同过程中的一致性; 通过 获取到该设定权限的令牌, 根据该设定权限的令牌对该待协同项目所对应的 项目模型进行操作处理, 提高了协同的安全性, 并且减少了多个用户之间的 数据传输量, 提高了多个用户之间的协同效率。
所属领域的技术人员可以清楚地了解到, 为描述的方便和简洁, 上述描 述的系统、 设备、 模块和单元的具体工作过程, 可以参考前述方法实施例中 的对应过程, 在此不再赘述。
