Hi,
I think we have agreed on this optimization strategy in previous discussions
on this ML. Venkat, do you know if we have implemented it (to skip
pass-by-value copy if the one end of the wire is a service or reference with
remote binding)?
Thanks,
Raymond

Based on the SCA spec, there are two semantics for parameters and return
values - pass-by-reference and pass-by-value. In the case of
pass-by-value with Web Service binding, after demarshalling, the data
object was newly created from the soap message (the original value) so
Tuscany should have no need to make another new copy of the data object
because this will have huge impact on performance.
Just want to make sure I am on the right track. Thanks.

Fuhwei,
That makes sense to me. We need to avoid multiple transformations and
unnecessary copies from XML to the form expected by the target component
implementation. If the target component implementation expects an SDO
DataObject, the DataObject should be created directly from the XML stream
out of the SOAP body.
