Public Methods

Remarks

This traits class is a supplement to the CSimpleMap class. It provides methods for comparing two CSimpleMap object elements (specifically, the key and value components) for equality. By default, the keys and values are compared using operator==(), but if the map contains complex data types that lack their own equality operator, this class can be overridden to provide the extra required functionality.
