alib::lang::TypeFunctors Struct Reference

Description:

This is a simple struct that features the use of std::type_info as key values of container types like hash tables and sets. For this, this struct provides inner functors hash, equal_to and less.

If for example a std::unordered_map should be instantiated with run-time type information as the hash key, a definition looks as follows:

 std::unordered_map<TypeFunctors::Key,      MyMappedType,
                    TypeFunctors::Hash,
                    TypeFunctors::EqualTo                  > myMap;

Note that the key type evaluates to const std::type_info*, hence pointers to the structs have to be given when interfacing with the container.
