bool
operator()(
LOOKUP_KEY const& lhs,
bslalg::RbTreeNode const& rhs) const;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.
