JsonMapper

Typed JSON parser for ActionScript

Uses built-in JSON class if available, also can fall back to pure ActionScript JSON parser implementation.

Usage

1. Put annotations ([Serialized(required=true/false)] and [ArrayElementType("type")]):

       public class JsonVO
       {
           [Serialized(required="true")]
           public var id:String = null;
   
           [Serialized]
           public var path:String = null;
   
           [Serialized(required="false")]
           public var name:String = null;
   
           [Serialized]
           public var description:String = null;
   
           [Serialized]
           public var value:Number;
   
           [Serialized]
           public var date:Date;
   
           [Serialized]
           [ArrayElementType("converter.rest.vo.JsonVO")]
           public var properties:Array;
   
           [Serialized]
           [ArrayElementType("String")]
           public var vector:Vector.<String> = Vector.<String>(["test", "test"]);
   
           [Serialized]
           [ArrayElementType("Boolean")]
           public var booleans:Array = [[true, false], [true, false]];
   
           [Serialized]
           [ArrayElementType("converter.rest.vo.JsonVO")]
           public var nested:Array = [];
   
           [Serialized]
           [ArrayElementType("int")]
           public var aCollection:ArrayCollection = new ArrayCollection([1, 2, 3]);
       }
   

2. Map entity:

       var mapper:JsonMapper = new JsonMapper();
       mapper.registerClass(JsonVO);
   

3. Decode JSON:

       var result:JsonVO = new JsonDecoder(mapper).decode(message, JsonVO);
