The Metadatum Class
Defined in: Keyview_Metadata.hpp
The Metadatum
class is the type returned by Session::get_metadata or Subfile::metadata to represent a single metadata item. The Metadatum
class has methods to inspect the name or type of the item, provide conversion to string for ease of transition from metadata_map
, and to provide access to the item in its original type (by using a Visitor Pattern implementation).
