-----------------------------------------------------------------------------
Key: TUSCANY-2300
URL: https://issues.apache.org/jira/browse/TUSCANY-2300
Project: Tuscany
Issue Type: Improvement
Components: C++ SDO
Reporter: Stanisław T. Findeisen
Fix For: Cpp-M3
Hello Tuscany Developers
Here at IBM Polska we wrote a patch for M3 addressing some performance issues.
It is short, so please read it - I hope it is self-explanatory.
Main areas of our development were:
(1) DataFactoryImpl::findTypeImpl --- we added new string hash based searching
of types.
(2) TypeImpl --- we added these maps:
std::map<const char*, int, TStrCmp> hmPropIdx; // property index by
property name
std::map<unsigned int, PropertyImpl*> propByIdx; // property by index
(3) DataObjectImpl::getPropertyIndex(const Property& p) and
DataObjectImpl::getProperty(unsigned int index) (make use of improvements in
TypeImpl)
(4) SDOXMLWriter --- we removed some conversions from std::list to std::vector
that we thought were unnecessary.
I hope you will be able to apply this patch and include it in the next release.
Let me know of you have any problems.
