Remarks

This class provides static functions for copying, moving, and comparing strings and for creating a hash value. These functions are useful when using a collection class to store string-based data. Use CStringElementTraitsI when case-insensitive comparisons are required. Use CStringRefElementTraits when the string objects are to be dealt with as references.
