** Module   : AbstractTTCollection.java
** Abstract : Implementation of the builtin class.

** Copyright (c) 2019-2023, Golden Code Development Corporation.
**
** -#- -I- --Date-- ---------------------------------------Description----------------------------------------
** 001 ME  20200514 First version, stubs taken by converting the skeleton using FWD.
** 002 CA  20210113 Renamed Iiterator.next to Iiterator.next_, to follow NameConverter's rules.
**         20210113 Renamed clear() to clear_(), to follow NameConverter's rules.
** 003 ME  20210128 Keep only the default 4GL temp-table implementation.
** 004 CA  20210221 Fixed 'qualified', 'extent' and 'returns' annotations at the legacy signature.
**     CA  20210609 Updated INPUT/INPUT-OUTPUT parameters to the new approach, where they are explicitly 
**                  initialized at the method's execution, and not at the caller's arguments.
**     ME  20210928 Fix return value on clone method, defined out of the function block.
**     CA  20220923 Variable definitions (including associated with parameters) must be done always outside of 
**                  the BlockManager API
**     CA  20220513 Renamed _BaseObject_.clone() to legacyClone(), as it can be overriden by sub-classes and
**                  the access mode may collide with the Java's Object.clone().
**     GES 20220520 Upgraded table-handle parameter processing to match API changes.
** 005 CA  20231113 The 'execute' method must be annotated with LegacySignature Type.Execute, and also can be
**                  dropped if is a no-op.
