    • The present invention provides a method, system, and computer program product for efficiently serializing navigational state into URLs or the header of the new portal page by using a complete stream-based serialization. The inventive serialization is divided into two sub-processes which are both stream-based. The first stream-based serialization sub-process which is hierarchy-oriented uses the hierarchical object representation of the navigational state and transforms it into a series of events. The events serve as the input for various strategies for compacting information that is associated with these events. At the end of the sub-process the compacted navigational state information carried by the received events is transformed into a character-based representation and the hierarchical structure of the navigational state is derived from the order of the received events and transformed into an additional character-based representation both being directly streamed to the second sub-process.The second stream-based serialization sub-process which is hierarchy-independent uses the result of the first sub-process and applies further compression and character encoding strategies and finally streams the compressed and character encoded information into a URL or header of said new Portal page.Both sub-processes are seamlessly linked together.The inventive stream-based serialization method is efficient because it minimizes the overall processing time needed to generate a URL and also effective because it makes sure that the serialization result is as short as possible to meet the requirements regarding URL length and markup size.
    • 本发明提供了一种通过使用完整的基于流的串行化来有效地将导航状态序列化为URL或新门户页面的头部的方法,系统和计算机程序产品。 本发明的序列化被分为两个基于流的子进程。 基于层次的第一个基于流的序列化子过程使用导航状态的分层对象表示,并将其转换为一系列事件。 这些事件是用于压缩与这些事件相关联的信息的各种策略的输入。 在子过程结束时,由接收到的事件承载的压缩导航状态信息被转换为基于字符的表示,并且导航状态的分层结构从接收到的事件的顺序导出并被转换为附加字符 - 直接流式传输到第二个子进程。 与层次无关的第二个基于流的序列化子过程使用第一个子过程的结果并应用进一步的压缩和字符编码策略,并最终将压缩和字符编码的信息流式化为所述新Portal页面的URL或头部 。 两个子进程都无缝连接在一起。 本发明的基于流的串行化方法是有效的,因为它最小化生成URL所需的整体处理时间并且也是有效的,因为它确保序列化结果尽可能短以满足关于URL长度和标记大小的要求。
