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);
