SpringActionscript

Getting StartedSimple example

Step1


SpringActionscript

applicationContext.xmlRegist component

<?xml version="1.0"?><objects xmlns="http://www.pranaframework.org/objects"

xmlns:xsi="http://www.w3.org/2001/XMLSchema‐instance"xsi:schemaLocation="http://www.pranaframework.org/objects

http://www.pranaframework.org/schema/objects/prana‐objects‐0.6.xsd"><object id="singletonBean"class="yone098.samples.SingletonClass" scope="singleton" />

<object id="prototypeBean“class="yone098.samples.PrototypeClass" scope="prototype" />

<object id="calc" class="yone098.samples.CalcAdd" /></objects>


SpringActionscript

scopeprototype

getObject毎にinstance⽣成objectタグで指定<object scope=“prototype” …

singleton(default)何度getObjectしても同じinstanceobjectタグで指定<object scope=“singleton” …


SpringActionscript


Step2


SpringActionscript

load config and lookup dependencyprivate var _appContext:XMLApplicationContext;private function onCreationComplete():void{

_appContext= new XMLApplicationContext("applicationContext.xml");_appContext.addEventListener(Event.COMPLETE,

onApplicationContextComplete); // listen complete_appContext.load(); // load

}private function onApplicationContextComplete(event:Event):void{

var bean1:SingletonClass = _appContext.getObject("singletonBean");var bean2:SingletonClass = _appContext.getObject("singletonBean");

}


SpringActionscript

applicationContext.xml<object><property><ref><constructor‐arg><arg><method‐invocation><param>


SpringActionscript

Tips1applicationContext.xmlにBeanを定義しただけではswfにclass情報は埋め込まれない為に,明⽰的にclassを宣⾔するか,cssにclass情報を設定しないと実⾏時にエラー。特にinterfaceでgetObjectする際は注意

// 明⽰的に実装クラスを宣⾔しておくprivate var _includeClasses:Array = [CalcAdd, CalcMinus];


SpringActionscript

Tips2明⽰的に宣⾔すると設定ファイルのみ書き換えて実装classの切り替えが出来ない＞＜新しい実装クラスの度にコンパイル

CSSを利⽤するClassReference

/** bean情報をcssに */.prana {bean1:ClassReference("yone098.samples.CalcAdd");bean2:ClassReference("yone098.samples.CalcMinus");

}


SpringActionscript

Tips3同⼀idでBeanを登録した場合,後の登録が有効登録してもエラーにはならない

<object id="calc" class="yone098.samples.CalcMinus" /><object id="calc" class="yone098.samples.CalcAdd" />

// id=calcをgetObjectするとCalcAddvar calc:ICalc = _appContext.getObject("calc");

useClassnamed(“xx”).useClassuseSingletonOf

// interfaceの実装をCalcAddに_injector.newRule().whenAskedFor(ICalc).useClass(CalcAdd);

// “calc”という名前でBinding_injector.newRule().whenAskedFor(ICalc).named("calc").useClass(CalcAdd);

// singleton_injector.newRule().whenAskedFor(ICalc).useSingletonOf(CalcAdd);


SmartyPants IOC

Class Binding Tips1namedでclass bindingしたinterfaceは, getInstanceの際にbindしたnamed指定で取得しないとエラー。

// namedで”foo”指定でbind_injector.newRule().whenAskedFor(ICalc).named("foo").useClass(CalcAdd);// bindした名前と異なるのでエラーvar calc:ICalc = _injector.newRequest(this).forClass(ICalc).named(“abc").getInstance();// 名前を指定しないとエラーvar calc:ICalc = _injector.newRequest(this).forClass(ICalc).getInstance();// 正しくgetInstance可能_injector.newRequest(this).forClass(ICalc).named("foo").getInstance();


SmartyPants IOC

Class Binding Tips2同⼀interfaceで複数実装classを登録した場合,後の登録が有効登録してもエラーにはならない

// 同⼀interfaceでnamed指定無しで複数登録_injector.newRule().whenAskedFor(ICalc).useClass(CalcAdd);_injector.newRule().whenAskedFor(ICalc).useClass(CalcMinus);

// getInstance => CalcMinusvar calc:ICalc =
