The following sample code illustrates subclassing custom reactors from AcMapOraclexxReactor classes. Classes and functions are declared, but function definitions, which would be highly implementation specific, are not shown. This is an example of what MyMapOracleReactors.h, one of the include files in the "Connecting to an Oracle Spatial Database" sample, would contain.
