JSON datatypes

With Lycia, JSON data interchanged is achieved by applying a number of methods to objects of two possible datatypes - util.JSONObject and util.JSONArray.

 

util.JSONObject is an object serving as a container for JSON objects:

DEFINE json_obj util.JSONObject

Methods available for util.JSONObjects are:

 

util.JSONArray is an object serving as a container for JSON arrays:

DEFINE json_arr util.JSONArray

Methods available for util.JSONArrays are:

 

Successful integration of JSON into Lycia requires from 4gl developers to be attentive and consistent with their coding.

We recommend you to use meaningful variables and thoroughly structure the 4gl code in order to ensure proper runtime behavior of your applications.
