Defined in header <functional>
template< class T >
struct less;

Function object for performing comparisons. Uses operator< on type T.

Contents

[edit] Notes

If the built-in operator< does not provide total order for pointers, a partial specialization of std::less for pointer types is provided, which guarantees total order.

[edit] Member types

type definition
result_type bool
first_argument_type T
second_argument_type T

[edit] Member functions

operator()
checks if the first argument is less than the second
(public member function)

std::less::operator()

bool operator()( const T& lhs, const T& rhs ) const;

Checks whether lhs is less than rhs.

Parameters

lhs, rhs - values to compare

Return value

true if lhs < rhs, false otherwise.

Exceptions

(none)
