Bryan:

 

I guess I am a little confused about how the distinction between Composite and Component plays in the C++ implementation model:.

Do you consider "composite" as just an implementation concept only? (i.e. no dedicated class).

I see composite mentioned as a COmponent implementation  "scope", so it seems  it does not have a construct or class on its own.

If that is the case that should be more clearly stated, as in the Assembly mark-up it appears that a component is always used inside a Composite - and not by itself.

So that would also address my question about the "promotion" concept in Assembly that relates the Services of a composite to the Service of a component inside.

 

 

Other comments:

 

- it is unclear what the notion of "SCA runtime" corresponds to in C++. Is there a particular framework or container (in C++) to manage components? For example, what entity is raising SCA Exceptions ? (as opposed to business exceptions).

 

- The ServiceProxy base class is empty... is it really needed?

 

- it looks like (in PDF) the table of contents is not uptodate: section 6.5 is announced as SCAExceptions, but it is actually 6.6.

 

Regards,

Jacques

Thank-you for comment on the 
formatting.  Definitely a PDF generation problem. 

Before the TC can fully consider your comment on 
promotion, would you be able to elaborate on what you think may be needed? 
 The promotion of services and reverences as defined in the Assembly 
specification is completely invisible to a component implementation and thus 
would not be reflected in an API or component/componentType definition.

The spec appears to cover a lot of ground for C/C++ developers. 
My only comments so far: 
  
-  in the PDF, title of 
section 6.4 seems to not be right (formatting issue?) 
  
- the "promotion" mechanism 
described in Assembly specification, does not seem to be addressed here.
