Wrapper ensuring a comparator's call operator is const-qualified.
Declared in <bslstl_hashtable.h>
template<class FUNCTOR>
class HashTable_ComparatorWrapper;This class provides a wrapper around a functor that can compare two values and return a bool, so that the function call operator is always declared as const qualified.
TBD Provide an optimization for the case of an empty base functor, where we can safely const_cast want calling the base class operator.
