util.JSONArray.fromFGL

Creates a new JSON array object from a DYNAMIC ARRAY.

Syntax

util.JSONArray.fromFGL(
   source DYNAMIC ARRAY )
  RETURNING array util.JSONArray

source is the DYNAMIC ARRAY variable used to create the JSON array object.

Usage

The util.JSONArray.fromFGL() method creates a new JSON array from the DYNAMIC ARRAY variable passed as parameter.

The new created object must be assigned to a program variable defined with the util.JSONArray type.

The members of the DYNAMIC ARRAY are converted to a list of name/value pairs in the JSON array object.

The dynamic array can be structured with a RECORD definition: the elements of the array will be converted individually.

Example

IMPORT util
MAIN
    DEFINE da DYNAMIC ARRAY OF INTEGER
    DEFINE arr util.JSONArray
    LET da[1] = 123
    LET da[2] = 972
    LET arr = util.JSONArray.fromFGL(da)
    DISPLAY arr.toString()
END MAIN
