ITcTypeInstance

ITcTypeInstance is the basic interface for data type and temporary type instances. It encapsulates XML serialization, name and GUID access, and the determination of dependent data types. For temporary type instances, only a subset of this functionality is available. Over the years, numerous follow-up ITcTypeInstanceX interfaces have been added, which introduce, among other things, C declarations, child navigation, value formatting, named constants, and namespace information.
