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).
