util.JSONArray.fromFGL()creates a new JSON array from a DYNAMIC ARRAY.
Syntax:
util.JSONArray.fromFGL(source)
Parameters:
|
source |
a DYNAMIC ARRAY variable from that the JSON array is created |
Usage and examples:
util.JSONArray.fromFGL() converts the members of the DYNAMIC ARRAY into the members of the JSON array.
An array newly created by util.JSONArray.fromFGL() must be assigned to a variable of the util.JSONArray data type.

Dynamic arrays can be structured with a RECORD definition: In this case, array members will be converted individually.
