-Providers will be required to implement the above functionality. Instead of each provider to implement all of newly added pure virtual functions, three utility abstract classes are added to provide the default implementation as mentioned above under Fdo/Utilities/Common: FdoIFeatureReaderDefault, FdoIDataReaderDefault, FdoISqlReaderDefault. Then the provider specific implementation will simply derive from the new classes. That involves changing one line in header file for each provider (some providers may not link {{{FdoCommon}}} and need to add that dependancy). Take FdoIDataReaderDefault as an example:
