less<T>

Category: functors Component type: type

Description

Less<T> is a function object. Specifically, it is an Adaptable Binary Predicate, which means it is a function object that tests the truth or falsehood of some condition. If f is an object of class less<T> and x and y are objects of class T, then f(x,y) returns true if x < y and false otherwise.

Example

Finds the first negative element in a list. 
list<int> L;
...
list<int>::iterator first_negative = 
       find_if(L.begin(), L.end(), bind2nd(less<int>(), 0));
assert(first_negative == L.end() || *first_negative < 0);

Definition

Defined in the standard header functional, and in the nonstandard backward-compatibility header function.h.
