LegacyConstructor.java

/*
** Module   : LegacyConstructor.java
** Abstract : Implementation of the Progress.Reflect.Constructor builtin class.
**
** Copyright (c) 2020-2023, Golden Code Development Corporation.
**
** -#- -I- --Date-- -------------------------------Description--------------------------------
** 001 ME  20200421 First version, stubs taken by converting the skeleton using FWD.
** 002 CA  20210221 Fixed 'qualified', 'extent' and 'returns' annotations at the legacy
**                  signature.
**     ME  20211028 Added 'POLY' return data type for invoke.
** 003 ME  20230829 Mark the object as not tracked/internal, remove default 4GL ctor.
** 004 CA  20231130 Do not use 'TypeFactory.object' in cases where the skeleton class is not instantiated via
**                  ObjectOps (like the reflection classes), as this will force pending ObjectOps scopeable 
**                  registration, which never gets executed, as the legacy constructors are not used.
