CSbcEncoderIntfc Class Reference

class CSbcEncoderIntfc : public CBase

Interface for configuring the SBC encoder. Used to configure the SBC encoder operating modes. This abstract class just provides the static NewL function for the creation of the proxy, and also defines the custom interface to be implemented by the proxy and the real custom interface implementation.
