hash_set::rend

참고

이 API는 사용되지 않습니다.unordered_set 클래스를 대신 사용하는 것이 좋습니다.

Returns an iterator that addresses the location succeeding the last element in a reversed hash_set.

const_reverse_iterator rend( ) const; 
reverse_iterator rend( );

반환 값

A reverse bidirectional iterator that addresses the location succeeding the last element in a reversed hash_set (the location that had preceded the first element in the unreversed hash_set).

설명

rend is used with a reversed hash_set just as end is used with a hash_set.

If the return value of rend is assigned to a const_reverse_iterator, then the hash_set object cannot be modified. If the return value of rend is assigned to a reverse_iterator, then the hash_set object can be modified. 이 rend 로 반환된 값은 역참조 되지 않아야 합니다.

rend can be used to test to whether a reverse iterator has reached the end of its hash_set.

예제

// hash_set_rend.cpp
// compile with: /EHsc
#include <hash_set>
#include <iostream>

int main( )
{
   using namespace std;
   using namespace stdext;
   hash_set <int> hs1;
   hash_set <int>::iterator hs1_Iter;
   hash_set <int>::reverse_iterator hs1_rIter;
   hash_set <int>::const_reverse_iterator hs1_crIter;

   hs1.insert( 10 );
   hs1.insert( 20 );
   hs1.insert( 30 );

   hs1_rIter = hs1.rend( );
   hs1_rIter--;
   cout << "The last element in the reversed hash_set is "
        << *hs1_rIter << "." << endl;

   // end can be used to terminate an iteration 
   // throught a hash_set in a forward order
   cout << "The hash_set is: ";
   for ( hs1_Iter = hs1.begin( ) ; hs1_Iter != hs1.end( );
         hs1_Iter++ )
      cout << *hs1_Iter << " ";
   cout << "." << endl;

   // rend can be used to terminate an iteration 
   // through a hash_set in a reverse order
   cout << "The reversed hash_set is: ";
   for ( hs1_rIter = hs1.rbegin( ) ; hs1_rIter != hs1.rend( );
         hs1_rIter++ )
      cout << *hs1_rIter << " ";
   cout << "." << endl;

   hs1_rIter = hs1.rend( );
   hs1_rIter--;
   hs1.erase ( *hs1_rIter );

   hs1_rIter = hs1.rend( );
   hs1_rIter--;
   cout << "After the erasure, the last element in the "
        << "reversed hash_set is " << *hs1_rIter << "."
        << endl;
}
