PSS — PSS FTF: Read-only operations on storage objects

  • Key: PSS-16
  • Legacy Issue Number: 3192
  • Status: closed  
  • Source: ZeroC ( Bernard Normier)
  • Summary:

    With some object oriented programming languages (C++, Ada95), it is
    possible to specify a method as read-only or read-write.
    For example in C++, a 'const' member function has read-only access
    to the data members of the target object.

    So far in IDL and PSDL, there is no way to mark an operation as
    read-only – this makes sense for interfaces, since a CORBA object
    exposes only operations, not state.
    For stateful objects, such as PSDL storage objects and IDL values,
    being able to specify an operation as read-only would be very
    useful. For example in C++ a 'in storage object' parameter
    could be mapped to a pointer to a const C++ object, which is exactly
    the semantics of 'in'. More generally, writing const-correct program
    in C++ (Ada etc.) with PSS would become possible.
