operator>(<iterator>)

연산자의 좌변의 반복기 개체가 우변의 반복기 개체보다 큰지 시험합니다.

template<class RandomIterator> 
   bool operator>( 
      const reverse_iterator<RandomIterator>& _Left, 
      const reverse_iterator<RandomIterator>& _Right 
   );

매개 변수

• _Left
  An object of type iterator.

• _Right
  An object of type iterator.

반환 값

true if the iterator on the left side of the expression is greater than the iterator on the right side of the expression; false if it is less than or equal to the iterator on the right.

설명

One iterator object is greater than another if it addresses an element that occurs later in the container than the element addressed by the other iterator object. One iterator object is not greater than another if it addresses either the same element as the other iterator object or an element that occurs earlier in the container than the element addressed by the other iterator object.
