Serializes legacy data as JSON.

FWJsonSerializeAdvPL

01 · OVERVIEW

Overview

Deprecated legacy function; TOTVS recommends JsonObject. It serializes AdvPL data to JSON text. Extra arguments control class names and date treatment; not every combination guarantees round-trip types. The example uses a simple integer array without dates, objects or credentials. Serialized output must exclude internal data unintended for consumers. (Sources: refs. 1–1.)
