Create an Array JSON object (Json class)
[Introduced in Model 204 7.6]
This function creates a Json object of the array type.
Syntax
%json = [%(Json):]Array[( [itemList])]
Syntax terms
| %json | Json object |
|---|---|
| [%(Json):] | The optional class name in parentheses denotes a virtual constructor. See "Usage notes", below, for more information about invoking a virtual constructor. |
| itemList | Zero or more Json objects (including null) that become the arrays original items. |
Usage notes
- If the array is to be dynamically populated, it might be easiest to simply specify Array with no parameters and ad items with the Add function.
- The added Json objects can be a mix of Json object types.
Examples
The following example creates a Json array whose items are a number, a boolean, a string, a null, and an object:
%json is object json ... %json = array(23.14069, false, "Gelfond", null, object)
