CORBA34 — CosExternaliazation Service (bug?)

  • Key: CORBA34-220
  • Legacy Issue Number: 4188
  • Status: closed  
  • Source: Anonymous
  • Summary:

    Page 2-7 of the CosExternalization Service Specification (April 2000)
    defines the following interfaces:
    CosStream::Node
    CosStream::Role
    CosStream::Relationship

    A CosStream::Node inherits from the CosStream::Streamable interface and
    therefore is a streamable object – it has an external_form_id attribute
    that enables a FactoryFinder to recreate the object using the
    create_uninitialized operation.

    Unfortunately, the CosStream::Role and CosStream::Relationship interfaces do
    not support the CosStream::Streamable interface and therefore are not
    "streamable;" in particular, there is no standard method to obtain a KEY for
    them when it is time to internalize them.

    Perhaps, I am missing something (it wouldn't be the first time , but
    having them support the Streamable interface would certainly make
    implementation much easier. Might I suggest the following:

    interface Role: CosGraphs::Role, CosStream::Streamable

    { ... }
    interface Relationship: CosGraphs::Relationship, CosStream::Streamable { ... }

    at a minimum this would permit the CosStream::Node internalize_node()
    operation and the CosStream::StreamIO read_graph() operation to use a KEY
    value in the FactoryFinder to instantiate the object, before it is
    internalized.
