hash_multimap : : espace libre (STL/CLR)
Removes all elements.
void clear();
Notes
The member function effectively calls hash_multimap : : effacement (STL/CLR)( hash_multimap : : démarrez (STL/CLR)(), hash_multimap : : fin (STL/CLR)()). You use it to ensure that the controlled sequence is empty.
Exemple
// cliext_hash_multimap_clear.cpp
// compile with: /clr
#include <cliext/hash_map>
typedef cliext::hash_multimap<wchar_t, int> Myhash_multimap;
int main()
{
Myhash_multimap c1;
c1.insert(Myhash_multimap::make_value(L'a', 1));
c1.insert(Myhash_multimap::make_value(L'b', 2));
c1.insert(Myhash_multimap::make_value(L'c', 3));
// display contents " [a 1] [b 2] [c 3]"
for each (Myhash_multimap::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(Myhash_multimap::make_value(L'a', 1));
c1.insert(Myhash_multimap::make_value(L'b', 2));
// display contents " [a 1] [b 2]"
for each (Myhash_multimap::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);
}
