Detailed Description

Canonical type map.

This structure is a helper for the get operator, that retains associations between static types (represented by the std::type_info structure) and a hash map of dynamic values.

This structure is used for dynamic type instances canonicalization, i.e. storage and retrieval of unique instances of structural elements in Vaucanson.
