CPP11 — C++ issue to coordinate with proposed resolution of issue 752

  • Key: CPP11-245
  • Legacy Issue Number: 1626
  • Status: closed

  • Summary:

    Summary: In coordination with the proposed resolution to the ORB Portability RTF
    Issue #752, add the following operations to PortableServer::ServantBase
    in section 20.34.1:

    class ServantBase

    { ... public: ... virtual InterfaceDef_ptr _get_interface() throw(SystemException); virtual Boolean _is_a(const char * logical_type_id) throw(SystemException); virtual Boolean _non_existent() throw(SystemException); ... }


    and change the last paragraph of section 20.34.1 to:

    The default implementation of the _default_POA() function provided by
    ServantBase returns an object reference to the root POA of the default
    ORB in this process — the same as the return value of an invocation of
    ORB::resolve_initial_references("RootPOA") on the default ORB. Classes
    derived from ServantBase can override this definition to return the POA
    of their choice, if desired.

    and add the following text at the end of section 20.34.1:

    ServantBase provides default implementations of the _get_interface(),
    _is_a(), and _non_existent() standard object reference operations that
    can be overridden by the object implementation if the default behavior
    is not adequate. These functions are called just like normal skeleton
    operations by the POA, so the programmer can use _this() and and the
    PortableServer::Current interface in the function bodies.

    The default implementation of the _get_interface() and _is_a() functions
    provided by ServantBase uses the interface associated with the skeleton
    class if it is static to determine its return value. If the skeleton is
    dynamic (see 20.36) it uses the _primary_interface() function to
    determine its return value.

    The default implementation of the _non_existent() function simply
    returns false.
