operator<= (multimap) (STL/CLR)

Artikel

Liste kleiner als oder gleicher Vergleich.

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

Parameter

left
Linker Container zu vergleichen.
right
Rechter Container zu vergleichen.

Hinweise

Die Operatorfunktion gibt !(right < left) zurück. Sie verwenden sie, um zu testen, ob left nicht nach right sortiert wird, wenn die beiden Multimaps verglichenes Element durch Element sind.

Beispiel

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