Adding Operations to a Server Session

For each component you must implement the global function ostcConnect(). Use the operation subtype constructors to construct each operation the component supports. Use ostc_ServerSession::addOperation() to register each operation. The Component Server calls ostcConnect() after ostcInitialize(), when the Server first starts up.

Note that for every Server running a given service, you must register every operation the service supports, even if the operation has a different transaction type from that of the Server. Note also that for each type of transaction used by operations in a given service, you must start at least one Server running the service and using that transaction type.

Example

void ostcConnect(ostc_ServerSession * session)
{
      session->addOperation(new txfer_operation());
      session->addOperation(new AddAccount());
      session->addOperation(new withdraw());
      session->addOperation(new deposit());
      session->addOperation(new balance());
}

txfer_operation() is a call to the operation subtype constructor for the operation being specified. You pass a pointer to an instance of the class. Include one call to addOperation() for each operation you want the component to support.

Declaration of Global Functions

A source or header file for your component must include the following declaration of the global functions you are responsible for implementing (including ostcConnect()):

extern "C" { 

#ifdef WIN32
__declspec( dllexport )  void ostcInitialize();
__declspec( dllexport )  void ostcConnect(ostc_ServerSession *);
__declspec( dllexport )  void ostcDisconnect(void);
#else
void ostcInitialize();
void ostcConnect(ostc_ServerSession *);
void ostcDisconnect(void);
#endif
}

Note that you must use C linkage when declaring these functions..

This use of _declspec is required for Windows platforms.
