IOPCUAClientConnectionCallback (ITF) ¶ INTERFACE IOPCUAClientConnectionCallback EXTENDS __SYSTEM.IQueryInterface This interface must be implemented to handle OPC UA connectin properly. It is used to inform the implementaiton on state changes of the UA connectin. Futher this interface is used to verify the OPC UA servers certificate and to retrieve the credentails used to activate the session. The callbacks are called when needed. The GetUserCredentials callback will not be called for connection using the AnonymousUserToken, as the VerifyServerCertificate callback will not be called for unprotected UA connections. Methods: ConnectionStateCallback GetUserCredentials VerifyServerCertificate Structure: ConnectionStateCallback (Method) GetUserCredentials (Method) VerifyServerCertificate (Method)
