:relfileprefix: ../../
:mrdocs:

This nested class defines a mechanism for comparing two objects of `value_type` by adapting an object of (template parameter) type `COMPARATOR`, which compares two objects of (template parameter) type `KEY` . Note that this class exactly matches its definition in the C++11 standard [map.overview]; otherwise, we would have implemented it as a separate component‐local class.
