    • The present invention extends to methods, systems, and computer program products for altering event lifetimes. Embodiments of the invention include using operators in an event-processing framework (algebra) to shorten (or “clip”) the duration of events. An operator can receive a primary event stream, a clip event stream, and condition as parameters. The operator clips the lifetime of an event in the primary stream to the next event in the clip stream that fulfills the condition. Altering event lifetimes can be used to facilitate cleaning event stream state, converting point events to a continuous signal, and creating and annotating session events.
    • 本发明扩展到用于改变事件寿命的方法,系统和计算机程序产品。 本发明的实施例包括在事件处理框架(代数)中使用操作符来缩短(或“剪切”)事件持续时间。 操作员可以接收主事件流,剪辑事件流和条件作为参数。 操作员将主流中的事件的生存期剪辑到满足条件的剪辑流中的下一个事件。 改变事件生命周期可以用于促进清除事件流状态,将点事件转换为连续信号,以及创建和注释会话事件。
