hash_set::crend
Returns a const iterator that addresses the location succeeding the last element in a reversed hash_set.
const_reverse_iterator crend( ) const;
Return Value
A const reverse bidirectional iterator that addresses the location succeeding the last element in a reversed hash_set Class (the location that had preceded the first element in the unreversed hash_set).
Remarks
crend is used with a reversed hash_set just as hash_set::end is used with a hash_set.
With the return value of crend, the hash_set object cannot be modified.
crend can be used to test to whether a reverse iterator has reached the end of its hash_set.
In Visual C++ .NET 2003, members of the <hash_map> and <hash_set> header files are no longer in the std namespace, but rather have been moved into the stdext namespace. See The stdext Namespace for more information.
Example
// hash_set_crend.cpp
// compile with: /EHsc
#define _DEFINE_DEPRECATED_HASH_CLASSES 0
#include <hash_set>
#include <iostream>
int main( )
{
using namespace std;
using namespace stdext;
hash_set <int> hs1;
hash_set <int>::const_reverse_iterator hs1_crIter;
hs1.insert( 10 );
hs1.insert( 20 );
hs1.insert( 30 );
hs1_crIter = hs1.crend( );
hs1_crIter--;
cout << "The last element in the reversed hash_set is "
<< *hs1_crIter << "." << endl;
}
The last element in the reversed hash_set is 10.
