multimap::clear (STL/CLR)
Entfernt alle Elemente.
void clear();
Hinweise
Die Memberfunktion wird effektiv multimap::erase (STL/CLR)(multimap::begin (STL/CLR)(),multimap::end (STL/CLR)()) an.Sie verwenden sie, um sicherzustellen, dass die gesteuerte Sequenz leer ist.
Beispiel
// cliext_multimap_clear.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();
// clear the container and reinspect
c1.clear();
System::Console::WriteLine("size() = {0}", c1.size());
c1.insert(Mymultimap::make_value(L'a', 1));
c1.insert(Mymultimap::make_value(L'b', 2));
// display contents " [a 1] [b 2]"
for each (Mymultimap::value_type elem in c1)
System::Console::Write(" [{0} {1}]", elem->first, elem->second);
System::Console::WriteLine();
c1.clear();
System::Console::WriteLine("size() = {0}", c1.size());
return (0);
}
