Member Function Documentation

virtual Session* OpcServerCallback::createSession	(	OpcUa_Int32	sessionID,
		const UaNodeId &	authenticationToken
	)

pure virtual

Creates a session object for the OPC server.

This callback allows the application to create its own session class derived from UaSession to store user specific information and to implement the user logon and user verfication.

Parameters

sessionID	Session Id created by the server application.
authenticationToken	Secret session Id created by the server application.

Returns: A pointer to the created session.

virtual UaServer* OpcServerCallback::createUaServer ( )

inlinevirtual

Optional method used to create an application specific UaServer object used as main entry point for the UA communication.

The SDK creates an instance of the UaServer class as default implementation.

Returns: UaServer object or NULL if the SDK should use the default implementation.

virtual UaStatus OpcServerCallback::logonSessionUser	(	Session *	pSession,
		UaUserIdentityToken *	pUserIdentityToken
	)

pure virtual

Validates the user identity token and sets the user for the session.

Parameters

pSession	Interface to the Session context for the method call
pUserIdentityToken	Secret session Id created by the server application.

Returns: Error code.
