Description

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.
