operator<= (map) (STL/CLR)

List less than or equal comparison.

template<typename Key,
    typename Mapped>
    bool operator<=(map<Key, Mapped>% left,
        map<Key, Mapped>% right);

Parameters

  • left
    Left container to compare.

  • right
    Right container to compare.

Remarks

The operator function returns !(right < left). You use it to test whether left is not ordered after right when the two maps are compared element by element.

Example

// cliext_map_operator_le.cpp 
// compile with: /clr 
#include <cliext/map> 
 
typedef cliext::map<wchar_t, int> Mymap; 
int main() 
    { 
    Mymap c1; 
    c1.insert(Mymap::make_value(L'a', 1)); 
    c1.insert(Mymap::make_value(L'b', 2)); 
    c1.insert(Mymap::make_value(L'c', 3)); 
 
// display contents " [a 1] [b 2] [c 3]" 
    for each (Mymap::value_type elem in c1) 
        System::Console::Write(" [{0} {1}]", elem->first, elem->second); 
    System::Console::WriteLine(); 
 
// assign to a new container 
    Mymap c2; 
    c2.insert(Mymap::make_value(L'a', 1)); 
    c2.insert(Mymap::make_value(L'b', 2)); 
    c2.insert(Mymap::make_value(L'd', 4)); 
 
// display contents " [a 1] [b 2] [d 4]" 
    for each (Mymap::value_type elem in c2) 
        System::Console::Write(" [{0} {1}]", elem->first, elem->second); 
    System::Console::WriteLine(); 
 
    System::Console::WriteLine("[a b c] <= [a b c] is {0}", 
        c1 <= c1); 
    System::Console::WriteLine("[a b d] <= [a b c] is {0}", 
        c2 <= c1); 
    return (0); 
    } 
 
 [a 1] [b 2] [c 3]
 [a 1] [b 2] [d 4]
[a b c] <= [a b c] is True
[a b d] <= [a b c] is False
