Prism V2 Tour (6)

This article is about the event. Events are used primarily for interaction.

Listening for events

I subscribe to some blog rss, if I subscribe to the blog posted a new article, the system (that is, catch shrimp) will help me crawl new RSS information

Very well understood, one side of the subscription (Subscribe), one party released (Publish).

Prism's Events

The PRISM abstract class Eventbase implements the subscription and publishing of events. The Compositepresentationevent class inherits from Eventbase for further encapsulation, which is a generic class, We can pass a parameter by compositepresentationevent.
