   Priority:  minor           |   Milestone:  3.5.0    
  Component:  FDO API         |     Version:  3.4.0    
   Severity:  3               |    Keywords:

 The FdoIFeatureReader interfaces provides the following method which gives
 raw access to the current geometry pointed to by the reader:

     FDO_API virtual const !FdoByte * !GetGeometry(!FdoString*
 propertyName, !FdoInt32 * count) = 0;

 For performance reasons the FdoIDataReader interface should provide the
 same method.  Currently with FdoIDataReader, the only way to obtain the
 geometry is via the following FdoIReader method:

     FDO_API virtual !FdoByteArray* !GetGeometry(!FdoString* propertyName)
 = 0;

 which allocates a copy of the data.  Callers then have a choice of which
 method to call, depending on their context.
