Category: functors |
Component type: type |
Description
Not_equal_to<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
not_equal_to<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 nonzero element in a list.
list<int> L;
...
list<int>::iterator first_nonzero =
find_if(L.begin(), L.end(), bind2nd(not_equal_to<int>(), 0));
assert(first_nonzero == L.end() || *first_nonzero != 0);
Definition
Defined in the standard header functional, and in the nonstandard
backward-compatibility header function.h.
