Declared in `<bslstl_mapcomparator.h>`

Return `true` if the specified `lhs` is less than (ordered before, according to the comparator held by this object) `value().first` of the specified `rhs` after being cast to `NodeType`, and `false` otherwise. The behavior is undefined unless `rhs` can be safely cast to `NodeType`.
