** -#- -I- --Date-- ---------------------------------------Description----------------------------------------
** 001 ME 20200514 First version, stubs taken by converting the skeleton using FWD.
** 20201120 Fix remove method return value, removeAll implementation is different
** https://proj.goldencode.com/issues/5010.
** 002 CA 20210113 Renamed Iiterator.next to Iiterator.next_, to follow NameConverter's rules.
** 003 CA 20210221 Fixed 'qualified', 'extent' and 'returns' annotations at the legacy
** signature.
** 004 CA 20231113 The 'execute' method must be annotated with LegacySignature Type.Execute, and also can be
** dropped if is a no-op.
