说明DAO是如何使用的。带源码说明。

import Decorator;
import Component;
/**
 * Adds responsibilities to the component.
 */

public class ConcreteDecorator extends Decorator {

	public ConcreteDecorator(Component component) {
		super(component);
	}

	private void addedBehavior() {
		// some extra functionality goes here
	}

	public void doSomething() {
		component.doSomething();
		addedBehavior();
	}
}
