virtual void com::softwareag::marketdata::MDMInterface::connect ( const std::string &  subKey, AP_MDM_StreamType  streamType, map_t &  ctrlParams  )

pure virtual

Connect Callback

This is called when a new subscription has been identified by the Market Data library and the adapter should subscribe to the external source for the symbol contained in the subKey. If successful setConnectSuccess() should called, else setConnectFailed().

Parameters

subKey	The unique subscription key for this connection generated by a call to getKey.
streamType	The data stream type this connection is for.
ctrlParams	The control parameters for this connection.

virtual void com::softwareag::marketdata::MDMInterface::disconnect ( const std::string &  subKey, AP_MDM_StreamType  streamType, map_t &  ctrlParams  )

pure virtual

Disconnect Callback

This is called when the last unsubscription for a symbol has been identified by the Market Data library and the adapter should unsubscribe from the external source for the symbol contained in the subKey. If successful setDisconnectSuccess() should called, else setDisconnectFailed().

Parameters

subKey	The unique subscription key for this disconnection.
streamType	The data stream type this disconnection is for.
ctrlParams	The control parameters for this disconnection.

virtual const char* com::softwareag::marketdata::MDMInterface::getKey ( const std::string &  symbol, int64_t  sourceId, AP_MDM_StreamType  streamType, map_t &  ctrlParams  )

pure virtual

Subscription Key Generation Callback

This is called when any subscription is received and the adapter should generate a subscription key. It is used to detect duplicate subscriptions. The basic structure of the key should be:-

• "symbol:streamType:sourceId:controlparam1=val1;controlParam2=val2;...:"

Parameters

symbol	The symbol this subscription is for.
sourceId	The source Id this subscription is for.
streamType	The data stream type this subscription is for.
ctrlParams	The control parameters for this subscription.

Returns

The generated subscription key.

virtual void com::softwareag::marketdata::MDMInterface::setMarketDataSession ( MarketDataSession *  mdSession )

pure virtual

setMarketDataSession Callback

This is called after initialization of MarketDataManager. Through MarketDataSession object users can perform connect/disconnect operations.

Parameters

mdSession

MarketDataSession object
