Description

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

Example

Sort a vector in descending order, rather than the default ascending order.

Vector<int> V;
...
sort(V.begin(), V.end(), greater<int>());

Definition

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

Template parameters

Parameter Description Default
T The type of greater's arguments.  

Model of

AdaptableBinaryPredicate, DefaultConstructible

Type requirements

T is LessThanComparable.

Public base classes

binary_function<T, T, bool>.

Members

Member Where defined Description
first_argument_type AdaptableBinaryPredicate The type of the first argument: T
second_argument_type AdaptableBinaryPredicate The type of the second argument: T
result_type AdaptableBinaryPredicate The type of the result: bool
greater() DefaultConstructible The default constructor.
bool operator()(const T& x, const T& y) BinaryFunction Function call operator. The return value is x > y.

New members

All of greater's members are defined in the AdaptableBinaryPredicate and DefaultConstructible requirements. Greater does not introduce any new members.
