我认为每个Java开发人员在其职业生涯中都有机会使用JAVA STRAM API。或者我更愿意说,你可能每天都在使用它。但是,如果将函数式编程的内置特性与其他一些语言(例如Kotlin)进行比较,您会很快意识到streamapi提供的方法数量非常有限。因此,社区创建了几个库,这些库仅用于扩展纯Java提供的API。今天,我将展示三个流行库提供...

Based on the aforementioned analysis, we presented a general architecture for such a system, and explained in detail about the history and comparison of different continuous logic-processing subsystems. The challenges and open questions for stream processing in IoT are also discussed in this chapter....
