less_equal<T>


Category: functors 
Component type: type 
Description
Less_equal<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_equal<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 nonpositive element in a list.
list<int> L;
...
list<int>::iterator first_nonpositive =
find_if(L.begin(), L.end(), bind2nd(less_equal<int>(), 0));
assert(first_nonpositive == L.end()  *first_nonpositive <= 0);
Definition
Defined in the standard header functional, and in the nonstandard
backwardcompatibility header function.h.
