If you've ever done any event-driven programming in the past, I think you'll find signals to be a refreshing change from the common practice of setting up an explicit event processing loop.

如果您过去曾经编写过事件驱动的程序，那么我认为您会发现，对于设置显式事件处理循环这一常见做法，使用信号是一个令人耳目一新的变化。

To enable the easier coding of advanced triggering scenarios,including event processing, a new configuration driven processing node called the Collector node has been added.

为了能够更容易地编码高级触发场景（包括事件处理），添加了一个新的配置驱动的处理节点，即 Collector 节点。

They are related to the notion of event processing, a technique for analyzing and controlling the complex series of interrelated events in Event-Driven Architectures (EDA).

这些功能与事件处理概念相关，事件处理是一种用于分析和控制事件驱动的体系结构(EDA)中相互关联事件组成的复杂系列。
