operator> (hash_map)
Tests if the hash_map object on the left side of the operator is greater than the hash_map object on the right side.
bool operator>(
const hash_map <Key, Type, Traits, Allocator>& _Left,
const hash_map <Key, Type, Traits, Allocator>& _Right
);
Parameters
_Left
An object of type hash_map._Right
An object of type hash_map.
Return Value
true if the hash_map on the left side of the operator is greater than the hash_map on the right side of the operator; otherwise false.
Remarks
The comparison between hash_map objects is based on a pairwise comparison of their elements. The greater-than relationship between two objects is based on a comparison of the first pair of unequal elements.
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_map_op_gt.cpp
// compile with: /EHsc
#define _DEFINE_DEPRECATED_HASH_CLASSES 0
#include <hash_map>
#include <iostream>
int main( )
{
using namespace std;
using namespace stdext;
hash_map <int, int> hm1, hm2, hm3;
int i;
typedef pair <int, int> Int_Pair;
for ( i = 0 ; i < 3 ; i++ )
{
hm1.insert ( Int_Pair ( i, i ) );
hm2.insert ( Int_Pair ( i, i * i ) );
hm3.insert ( Int_Pair ( i, i - 1 ) );
}
if ( hm1 > hm2 )
cout << "The hash_map hm1 is greater than the hash_map hm2." << endl;
else
cout << "The hash_map hm1 is not greater than the hash_map hm2." << endl;
if ( hm1 > hm3 )
cout << "The hash_map hm1 is greater than the hash_map hm3." << endl;
else
cout << "The hash_map hm1 is not greater than the hash_map hm3." << endl;
}
The hash_map hm1 is not greater than the hash_map hm2. The hash_map hm1 is greater than the hash_map hm3.
