Subclassing Custom Reactors
Connecting to an Oracle Spatial Database
The following code sample illustrates connecting to an Oracle database and adding custom reactors.
Custom reactor declarations are in MyMapOracleReactors.h, one of the files included at the beginning of the sample. The "Subclassing Custom Reactors" sample shows what such a file would contain.
#include "StdAfx.h"
#include "StdArx.h"
#include "AdMapOracleConnection.h"
#include "MyMapOracleReactors.h" // Custom reactors
BOOL ConnectToOracle()

// Initialize reactors
MyConnectionReactor *pConnectReactor = new MyConnectionReactor();
MyExportReactor *pExportReactor = new MyExportReactor();
MyImportReactor *pImportReactor = new MyImportReactor();
// Add reactors to connection object
pConnection->AddConnectionReactor(pConnectReactor);
pConnection->AddExportReactor(pExportReactor);
pConnection->AddImportReactor(pImportReactor);
// Make the connection
