boost::algorithm::is_not_greater — is_not_greater functor
struct is_not_greater { // public member functions template<typename T1, typename T2> bool operator()(const T1 &, const T2 &) const; };
Convenient version of standard std::not_greater_to. Operation is templated, therefore it is not required to specify the exact types upon the construction
is_not_greater
template<typename T1, typename T2> bool operator()(const T1 & Arg1, const T2 & Arg2) const;
