Observer Pattern

基本解釋

Figure 1 illustrates how the Observer pattern works.
圖 1 顯示了觀察者模式的機(jī)制。
Thus, at a high level, the Observer pattern provides a simple asynchronous model.
因此，從一個(gè)較高的層次上，觀察者模式提供了一種簡單的異步模型。
The Observer pattern is associated with a single source of events, however, whereas the Reactor pattern is associated with multiple sources of events.
不過，觀察者模式與單個(gè)事件源關(guān)聯(lián)，而反應(yīng)器模式則與多個(gè)事件源關(guān)聯(lián)。
