Geoff Winn resolved TUSCANY-1136.
---------------------------------
Resolution: Fixed
Revised use of Type::getProperties built and tested on XP, RHEL3 and Ubuntu.
Using sdotest, callgrind shows time spent in getProperties dropped from just
over 30% to just under 5%.
> [SDO for C++] getProperties returns a copy of the property list which is
> expensive and often unnecessary

> URL: https://issues.apache.org/jira/browse/TUSCANY-1136
> Project: Tuscany
> Issue Type: Improvement
> Components: C++ SDO
> Affects Versions: Cpp-current
> Environment: All
> Reporter: Geoff Winn
> Assigned To: Geoff Winn
> Fix For: Cpp-current
>
>
> The Type::getProperties method returns a PropertyList object. This behaviour
> is required by the specification however it is inefficient when the
> PropertyList in question is subsequently used in a read-only manner - which
> is the common case within SDO. According to callgrind, approximately 30% of
> the execution time of the sdotest program is spent in getProperties. By
> adding a new method, such as
> const PropertyList& Type::getPropertyListReference()
> we can preserve the interface required by the specification but give
> ourselves the option to use the more efficient form whenever possible.
