Alf::IAlfVariantType Class Reference

class Alf::IAlfVariantType

An interface for variant data type. Application-specific data source classes may implement this interface. Alternatively, a wrapper class may be implemented to convert data fields from application source to some IAlfVariantType implementation (e.g., CAlfVariantType).
