| 1. | The observer design pattern
观察者设计模式 |
| 2. | By using the observer design pattern , you ve reduced the coupling between the event source and listeners
通过使用观察者设计模式，您已经减少了事件源与侦听器之间的耦合。 |
| 3. | The observer design pattern defines a many - to - one dependency between event listeners and an event creator
观察者设计模式定义了事件侦听器与事件创建者之间的多对一依赖关系。 |
| 4. | Those familiar with design patterns in object - oriented programming will notice the observer design pattern
（那些熟悉面向对象编程中的设计模式的人将注意到观察程序设计模式。 |
| 5. | Implementing the observer design pattern is fairly straightforward when the entire application is written in the java language
如果整个应用程序都使用java编程语言编写，实现观察者设计模式相当简单。 |
| 6. | The java programming language provides support for defining event listeners based on the observer design pattern , but this isn t sufficient when you need to use objects written in other languages
Java编程语言为定义基于观察者设计模式（ observer design pattern ）的事件侦听器提供了支持，但当您需要使用以其他语言编写的对象时，这还不够。 |
| 7. | Jobserver is one of two abstract classes that implement the observer design pattern . ? a class that extends jobserver is able to attach itself to a jobservable object and observe the state of the observable object . ? this is an equivalent of the jobserver object listening for an event fired by the jobservable class it is attached to
实现观察者模式的两个抽象类之一，从观察者类扩展的类能够负载于一个观察对象，并且能够观察对象的状态变化，这相当于观察者对象接受由被观察对象触发的事件。 |
