Summary
Operators for the C++ Standard Template Library
Data Type and Member Function Indexes
(exclusive of constructors and destructors)
None
Synopsis
#include <utility>
namespace rel_ops {
template <class T>
bool operator!= (const T&, const T&);
template <class T>
bool operator> (const T&, const T&);
template <class T>
bool operator<= (const T&, const T&);
template <class T>
bool operator>= (const T&, const T&);
}
Description
To avoid redundant definitions of operator!= out of operator== and of operators >, <=, and >= out of operator<, the library provides these definitions:
operator!= returns !(x==y),
operator> returns y<x,
operator<= returns !(y<x), and
operator>= returns !(x<y).
To avoid clashes with other global operators these definitions are contained in the namespace rel_ops. To use them either scope explicitly or provide a using declaration (e.g., using_namespace_rel_ops).
