** Module   : MessageWriterBuilder.java
** Abstract : Implementation of the builtin class.
**
** Copyright (c) 2019-2023, Golden Code Development Corporation.
**
** -#- -I- --Date-- ---------------------------------------Description----------------------------------------
** 001 CA  20190526 First version, stubs taken by converting the skeleton using FWD.
** 002 CA  20191024 Added method support levels and updated the class support level.
** 003 MP  20200611 Modify methods to match converting code signature.
**         20201218 Implement as of OE12.2.
**         20210208 Fix static registry property initialization.
** 004 CA  20210221 Fixed 'qualified', 'extent' and 'returns' annotations at the legacy signature.
**     ME  20210310 Add block 'referent' for static methods, use initInput for object params.
**     ME  20210330 Fix registry class type.
** 005 ME  20210519 Fix registry lazy loading.
**     CA  20220120 Do not used TypeFactory.object when the OO reference must not be tracked or registered.
**                  Do not use TypeFactory.object for internal usages, use ObjectVar if the reference must 
**                  be tracked.
**                  All TypeFactory.object variable definitions must be done outside of the top-level block.
** 006 CA  20231113 The 'execute' method must be annotated with LegacySignature Type.Execute, and also can be
**                  dropped if is a no-op.
