DDSXTY11 — Semantics of overriding an attribute not clearly specified

Open Closed All
  • Key: DDSXTY11-11
  • Legacy Issue Number: 18299
  • Status: closed  
  • Source: ZettaScale Technology ( Mr. Erik Hendriks)
  • Summary:

    Is it allowed to have a parent and a child struct share an attribute with the same name?

    • In most OO-languages this is allowed.
    • However, in scenario's like type-refactoring this will cause huge problems.

    We should clearly specify whether or not this is allowed, and when allowed we should clearly describe the consequences.

  • Disposition: Resolved — DDS-XTypes 1.1
  • Disposition Summary:

    The paragraph 7.2.2.3.5.1 updated as follows:
    A structure can optionally extend one other structure, its “base_type.” In the event that there is a name or ID collision between a structure and its base type, the definition of the member in the former takes precedence the definition of the derived structure is ill-formed.
