Flex处理Java返回的容器类型

当然，这个话题是建立在使用BlazeDS处理RemoteObject的情况下的。 

1.List和Set

当Java返回List和Set的时候，Flex可以用ArrayCollection进行处理。

		List list = new ArrayList();
		list.add(new Users("abc", "123"));
		list.add(new Users("efg", "123"));
		list.add(new Users("hij", "456"));
		return list;

 

		Set set = new HashSet();
		set.add(new Users("abc", "123"));
		set.add(new Users("efg", "123"));
		set.add(new Users("hij", "456"));
		return set;

  

			private function resultHandler(event:ResultEvent):void {
				var array:ArrayCollection = event.result as ArrayCollection;
				var str:String = "";
				for(var i:int = 0; i < array.length; i++) {
					var anUser:Users = array.getItemAt(i) as Users;
					str += anUser.userName + ":" + anUser.passWord + "\n";
				}

				resultMessage.text = str;
			}

2.Map

 Map在actionscript中是视为Object的，只需知道Map的key，就可以用".key"来得到Map的value了。

		Map map = new HashMap();
		map.put("one", anUser);
		map.put("two", anUser);
		map.put("three", new Users("abc", "123"));
		map.put("four", new Users("efg", "123"));
		map.put("five", new Users("hij", "456"));
		return map;	

 

			private function resultHandler(event:ResultEvent):void {
				var str:String = "";
				
				var anUser:Users = event.result.one as Users;
				str += anUser.userName + ":" + anUser.passWord + "\n";
				anUser = event.result.two as Users;
				str += anUser.userName + ":" + anUser.passWord + "\n";
				anUser = event.result.three as Users;
				str += anUser.userName + ":" + anUser.passWord + "\n";
				anUser = event.result.four as Users;
				str += anUser.userName + ":" + anUser.passWord + "\n";
				anUser = event.result.five as Users;
				str += anUser.userName + ":" + anUser.passWord + "\n";

				resultMessage.text = str;
			}
