as-spring: ActionScript IOC framework

as-spring is an ActionScript IOC framework, used to define and use dynamic objects without re-compile the source code.

Example

<?xml version="1.0" encoding="utf-8"?>
<spring-config>
	<beans>
		<bean id="textFieldBean" class="flash.text.TextField">

			<property name="text" value="Hello World"/>
			<property name="width" value="300"/>
			<property name="x" value="160"/>
			<property name="y" value="100"/>

			<method name="setTextFormat">
				<method-arg>
					<bean class="flash.text.TextFormat">
						<property name="color" value="0x003366"/>
						<property name="bold" value="true"/>
						<property name="size" value="36"/>
					</bean>
				</method-arg>
			</method>

		</bean>
	</beans>
</spring-config>

import com.colorhook.spring.context.ContextLoader;

var contextLoader:ContextLoader = new ContextLoader();
contextLoader.addEventListener(Event.COMPLETE, onContextLoaderComplete);
contextLoader.load("as-spring.xml");

function onContextLoaderComplete(e){
	contextLoader.removeEventListener(Event.COMPLETE, onContextLoaderComplete);
	var bean:* = contextLoader.contextInfo.getBean("textFieldBean");
}

element bean

element bean是最简单也是最基础的bean，它代表最基本的数据结构

...
<element id='num' value='200' type='int'/>
<element id='num2' value='200' type='uint'/>
<element id='num3' value='200' type='Number'/>
<element id='str'><value>string type data</value></element>
<element id='arr'><value>[1,2,3,4]</value></element>
<element id='bool'><value>true</value></element>
...

list bean

list bean是一个数组对象，用于存放数组结构的数据

...
<list id='myList'>
  <element value='1' type='int'/>
  <element value='2'/>
  <element value='false' type='Boolean'/>
  <list>
  	<element value='4'/>
  	<element value='5'/>
  </list>
</list>
...

var list:Array = contextInfo.getBean('myList') as Array;
trace(list); // [1, '2', false, ['4', '5']]

map bean

map bean是一个Hash对象，用于存放键值对结构的数据

...
<map id='myMap'>
  <key name='name' value='as-spring'>
  <key name='version'>2.x</key>
  <key name='info'>
  	<map>
  		<key name='contributors'>
			<list>
			</list>
		</key>
  		<key name='github'>
			<value>http://github.com/colorhook/as-spring</value>
		</key>
  	</map>
  </key>
</map>
...

var map:* = contextInfo.getBean('myMap');
trace(map); // {name: 'as-spring', version: '2.x', 
			//  info: {contributors: [], github:'http://github.com/colorhook/as-spring'}}

singleton bean

bean可以是singleton类型的，即一个bean只会有单一实例

...
<bean id='sprite' type='flash.display.Sprite' singleton='true'>
</bean>
...

var s1:Sprite = contextInfo.getBean('sprite') as Sprite;
var s2:Sprite = contextInfo.getBean('sprite') as Sprite;
trace(s1 === s2); //true

factory bean

factory bean表示一个bean不是通过new关键字创建的，而是通过工厂方法创建的

package{
	public class Factory{

		public static function getObject():*{
			return xxx;
		}
	}
}

...
<bean id='obj' class='Factory' factory-method='getObject'>
</bean>
...

var obj:* = contextInfo.getBean('obj');

通过swf文件反射bean

可以在一个SWF文件中输出class，然后在另一个SWF中通过bean的方式加载使用这个class

...
<classes>
	<class name='app.MyClass' lib='app.MyClass.swf'/>
</classes>
<beans>
	<bean id='app' class='app.MyClass'/>
</beans>
...

var app:* = contextInfo.getBean('app');
