<div class="exampleIntro"> |

<p> |
|
|
109 |
This example builds on the <a href="attribute-basic.html">"Basic Configuration" example</a>, |
|
|
110 |
showing how you can use attribute to model objects in your application. |
|
|
111 |
</p> |
|
|
112 |
|
|
|
113 |
<p> |
|
|
114 |
As with the basic example, it is geared towards users who want to create their own classes from |
|
|
115 |
scratch and add attribute support. In most cases you should consider extending the |
|
|
116 |
<a href="http://developer.yahoo.com/yui/3/base/index.html"><code>Base</code></a> class when you need attribute support, instead |
|
|
117 |
of augmenting Attribute directly. <a href="http://developer.yahoo.com/yui/3/base/index.html"><code>Base</code></a> does the work described |
|
|
118 |
in this example for you, in addition to making it easier for users to extend you class. |
